Introduction This chapter presents the Security Target (ST) identification information and an overview. An ST contains the Information Technology (IT) security requirements of an identified Target of Evaluation (TOE) and specifies the functional and assurance security measures offered by the TOE. 1.1 ST Reference This section provides information needed to identify and control this ST and its Target of Evaluation. ST Identification ST Title: Gigamon GigaVUE Security Target ST Version: 1.0 ST Publication Date: August 21, 2018 ST Author: Booz Allen Hamilton Document Organization Chapter 1 of this document provides identifying information for the ST and TOE as well as a brief description of the TOE and its associated TOE type. Chapter 2 describes the TOE in terms of its physical boundary, logical boundary, exclusions, and dependent Operational Environment components. Chapter 3 describes the conformance claims made by this ST. Chapter 4 describes the threats, assumptions, objectives, and organizational security policies that apply to the TOE. Chapter 5 defines extended Security Functional Requirements (SFRs) and Security Assurance Requirements (SARs). Chapter 6 describes the SFRs that are to be implemented by the TSF. Chapter 7 describes the SARs that will be used to evaluate the TOE. Chapter 8 provides the TOE Summary Specification, which describes how the SFRs that are defined for the TOE are implemented by the TSF. Terminology This section defines the terminology used throughout this ST. The terminology used throughout this ST is defined in Table 1 and 2. These tables are to be used by the reader as a quick reference guide for terminology definitions. Term Definition Administrator A user who is assigned the Admin role on the TOE and has the ability to manage the TSF. Table 1-1: Customer Specific Terminology Security Target Gigamon GigaVUE 6 | P a g e Term Definition Security Administrator The claimed Protection Profile defines a single Security Administrator role that is authorized to manage the TOE and its data. This TOE defines three separate user roles, but only the most privileged role (Admin) is authorized to manage the TOE’s security functionality and is therefore considered to be the Security Administrator for the TOE. Trusted Channel An encrypted connection between the TOE and a system in the Operational Environment. Trusted Path An encrypted connection between the TOE and the application a Security Administrator uses to manage it (web browser, terminal client, etc.). User In a CC context, any individual who has the ability to access the TOE functions or data. Table 1-2: CC Specific Terminology Acronyms The acronyms used throughout this ST are defined in Table 3.

Security Target Gigamon GigaVUE 8 | P a g e Each appliance runs the Gigamon GigaVUE-OS software version 5.1.01. 1.3 TOE Overview The Gigamon GigaVUE Visibility Appliance (also known as GigaVUE or the TOE) is a network device that includes hardware and software. In the evaluated configuration, the TOE is a standalone device that is not deployed as a distributed TOE. The GigaVUE is a family of products that provide different performance and capability specifications; the TOE includes the models listed in section 1.2 above. These devices can be accessed locally via serial port and remotely via SSH CLI and TLS/HTTPS web GUI. The GigaVUE's primary functionality is to use the Gigamon Forwarding Policy to receive out-of-band copied network data from external sources (TAP or SPAN port) and forward that copied network data to one or many tool ports for packet capture or analyzing tools based on user selected criteria. GigaVUE can also copy the network traffic itself when sitting in-line with the network flow using passive, inline and bypass taps or any combination. GigaVUE features extensive filtering abilities enabling authorized users to forward precise customized data flows of copied data from many sources to a single tool, from a single source to many tools, or from many sources to many tools. A GigaVUE model:  Receives a copy (or copies internally) network traffic  Filters copied data based upon user selected criteria  Forwards copied data to user selected ports GigaVUE receives data from many sources, or networks. It can receive data from a 3rd party TAP or SPAN port. The GigaVUE can also be configured to be its own TAP. The internal TAP can be electrical so that it sits in line and copies the data, allowing the network traffic to continue to flow through unimpeded. GigaVUE also features an optical TAP that sits in line with production network and splits the light passing through the optical splitter making a copy of the network traffic. GigaVUE can also act as a bypass TAP or a GigaTap. In this configuration, GigaVUE connects to both sides of an IPS or other in-line device and monitors both itself and the in-line device. Specifically, the GigaVUE copies network traffic creating copied network data, filters it, and sends it to tools. The GigaVUE Bypass TAP will then forward the data to the IPS or other in-line device, allow the device to perform its own designated functionality, and then receive the data again from the same device. The GigaVUE will then process the data a second time using the same functionality to copy the network traffic after the in-line device process. Then the GigaVUE Bypass TAP will send the network traffic out to the production network. The GigaTap is a TAP that has the ability to split and copy inbound or outbound data streams. GigaVUE forwards the data received via a network port to a tool port based on user configured policy. Tool ports are physically connected to a packet capture or other analyzing tools. Any type of tool can be attached to the tool port such as an IDS, forensic data recorder, sniffer, or protocol analyzer. Multiple GigaVUE devices can also be physically connected over a stacking port in order to perform load balancing or to use a larger number of tools than is supported by a single device. However, this distributed model is outside the scope of the evaluated configuration. The TOE was evaluated as a standalone network device only and the GigaVUE’s network traffic capture, filter, and forwarding Security Target Gigamon GigaVUE 9 | P a g e capabilities described above were not assessed during this evaluation. Only the functionality described in section 6 of this Security Target is considered to be within the logical boundary of the TOE. The following figure depicts the TOE boundary.

The external interfaces that are relevant to the TOE boundary are the local and remote administrative interfaces, an Update Server interface (whether maintained by Gigamon or residing in the local network), an LDAP server interface (for externally-defined I&A), and a Syslog Server interface (for external audit log storage). The TOE also interfaces with a Certification Security Target Gigamon GigaVUE 10 | P a g e Authority (CA) for issuance of server certificates and publication of a Certificate Revocation List (CRL) to determine the validity of certificates presented to the TOE. 1.4 TOE Type The TOE type for this product is Network Device. The product is a hardware appliance whose primary functionality is related to the handling of network traffic. The NDcPP defines a network device as “a device composed of hardware and software that is connected to the network and has an infrastructure role within the network.” The TOE is a network device composed of hardware and software that is connected to the network and accepts packets of data, filters them and passes them to tools for further analysis. The device’s role in the enterprise network is to direct out-of-band network traffic for analysis by various tools, so its infrastructure role is self-evident. 2 TOE Description This section provides a description of the TOE in its evaluated configuration. This includes the physical and logical boundaries of the TOE. 2.1 Evaluated Components of the TOE The following table describes the TOE components in the evaluated configuration: Component Definition GigaVUE-HD8 14RU fabric node GigaVUE-HD4 5RU fabric node GigaVUE-HC3 3RU fabric node GigaVUE-HC2 2RU fabric node GigaVUE-HC1 1RU fabric node GigaVUE-TA100 1RU traffic aggregator GigaVUE-TA10 1RU traffic aggregator GigaVUE-TA40 1RU edge node Table 2-1: Evaluated Components of the TOE 2.2 Components and Applications in the Operational Environment The following table lists components and applications in the TOE’s operational environment that must be present for the TOE to be operating in its evaluated configuration: Component Definition Certification Authority A server that acts as a trusted issuer of digital certificates and distributes a CRL that identifies revoked certificates. LDAP Server A system that is capable of receiving authentication requests using LDAP over TLS and validating these requests against identity and credential data that is defined in an LDAP directory. Management Workstation Any general-purpose computer that is used by an administrator to manage the TOE. The TOE can be managed remotely, in which case the management workstation requires an SSH client to access the CLI or a web browser (Microsoft Internet Explorer 11 or higher and Google Chrome 36 or higher) to access the web GUI, or Security Target Gigamon GigaVUE 11 | P a g e locally, in which case the management workstation must be physically connected to the TOE using the serial port and must use a terminal emulator that is compatible with serial communications. Syslog Server The Syslog Server connects to the TOE and allows the TOE to send Syslog messages to it for remote storage. This is used to send copies of audit data to be stored in a remote location for data redundancy purposes. Update Server A general-purpose computer that includes a web server and is used to store software update packages that can be retrieved by the TOE using TLS/HTTPS. The Update Server can be a server maintained by Gigamon or it can be set up locally in the Operational Environment by an administrator if the TOE’s deployment prevents it from being able to access Gigamon’s web domain. Table 2-2: Evaluated Components of the Operational Environment 2.3 Excluded from the TOE The following optional products, components, and/or applications can be integrated with the TOE but are not included in the evaluated configuration. They provide no added security related functionality for the evaluated product. They are separated into three categories: not installed, installed but requires a separate license, and installed but not part of the TSF. Not Installed There are no optional components that are omitted from the installation process. Installed but Requires a Separate License There are no excluded components that are installed and require a separate license. Installed but Not Part of the TSF  Insecure mode of operation – GigaVUE provides an ‘Secure Cryptography Mode’ that restricts the cryptographic algorithms and ciphersuites to what is claimed in the Security Target. Operating the product outside of this mode of operation is not within the scope of the TSF  SCP/SFTP/FTP/TFTP mode of updating – GigaVUE provides several methods to download product updates from the Operational Environment. In the evaluated configuration, only the TLS/HTTPS method of downloading is permitted, and the remaining methods are not part of the TOE.  TLS mode of syslog handling – GigaVUE provides an additional method of off-loading the audit data using a TLS connection to the syslog server. In the evaluated configuration, only the SSH method of sending audit records is permitted and the remaining methods are not part of the TOE.  Port Blades, TAP Modules, Bypass Combo Modules and Port Modules – Modular components of the GigaVUE used to capture traffic from the network in a variety of methods, for different scenarios, and to support different types of network media. GigaVUE’s network traffic capture, filter, and forwarding capabilities were not assessed during this evaluation. Security Target Gigamon GigaVUE 12 | P a g e  Stacking – Combining multiple GigaVUE devices through a dedicated network port for the purpose of load balancing or to forward traffic received by one device to a tool connected to another device.  Telnet – GigaVUE supports both Telnet and SSH2 for remote administration. In the evaluated configuration Telnet will be disabled. Additionally, the TOE includes a number of functions that are outside the scope of the claimed Protection Profile. These functions are not part of the TSF because there are no SFRs that apply to them. 2.4 Physical Boundary Hardware GigaVUE is a rack-mounted hardware device.

Note that the GigaVUE software is built on top of the following CentOS versions. GigaVUE OS CentOS HD4/HD8, HC2, TA10, TA40 CentOS 5.8 HC1, HC3, TA100 CentOS 6.6 Table 2-6: Software Versions 2.5 Logical Boundary The TOE is comprised of several security features. Each of the security features identified above consists of several security functionalities, as identified below. Security Audit Security Target Gigamon GigaVUE 15 | P a g e Cryptographic Support Identification and Authentication Security Management Protection of the TSF TOE Access Trusted Path/Channels Security Audit Audit records are generated for various types of management activities and events. The audit records include the date and time stamp of the event, the event type and subject identity. In the evaluated configuration, the TSF is configured to transmit audit data to a remote Syslog Server using SSHv2, but audit data is also stored locally to ensure availability of the data if communications with the Syslog Server are unavailable. Local audit records are stored in “message” files which are rotated to ensure a maximum limit of disk usage is enforced. Only users with the Admin privilege can access or delete the log files. Users with the Admin privilege are considered trusted users and are therefore not expected to delete or modify the audit records. Cryptographic Support The TOE uses sufficient security measures to protect its data in transmission by implementing cryptographic methods and trusted channels. The TOE uses SSH to secure the remote CLI and Syslog Server trusted channels. The TOE also uses TLS/HTTPS to secure the trusted channels for the secure web GUI, Update Server and LDAP server. SSH communications are established using Diffie-Hellman group 14 while TLS communications are established using the ECC scheme using NIST curve P-256. Cryptographic keys are generated using the CTR_DRBG provided by this module. The TOE erases all plaintext secret and private keys that reside in both RAM and non-volatile storage with zeroes. In the evaluated configuration, the TOE operates in “Secure Cryptography Mode” which is used to restrict algorithms to meet the PP requirements. The following table contains the CAVP algorithm certificates: SFR Algorithm CAVP Cert. # FCS_CKM.1 FCS_COP.1/SigGen ECDSA #1492 FCS_CKM.2 CVL #1981 FCS_COP.1/DataEncryption AES #5541 FCS_COP.1/Hash SHS #4447 FCS_COP.1/KeyedHash HMAC #3692 FCS_RBG_EXT.1 DRBG #2196 Table 2-7: Cryptographic Algorithm Table Identification and Authentication All users must be identified and authenticated to the TOE before being allowed to perform any actions on the TOE. This is true of users accessing the TOE via the local console, or protected paths using the remote CLI via SSH or web GUI via TLS/HTTPS. Users authenticate to the TOE using one of the following methods: Security Target Gigamon GigaVUE 16 | P a g e  Username/password (defined on the TOE)  LDAP authentication  Username/public key (SSH only) The TSF provides a configurable number of maximum consecutive authentication failures that are permitted by a user. Once this number has been met, the account is locked for a configurable time interval. Passwords that are maintained by the TSF can be composed of upper case, lower case, numbers and special characters. The Security Administrator can define the password length between 8 and 30 characters. Password information is never revealed during the authentication process including during login failures. Before a user authenticates to the device, a configurable warning banner is displayed. As part of establishing trusted remote communications, the TOE provides X.509 certificate functionality. In addition to verifying the validity of certificates, the TSF can check their revocation status using a certificate revocation list (CRL). The TSF can also generate a Certificate Signing Request in order to obtain a signed certificate to install for its own use as a TLS server. Security Management The TOE defines two roles: Admin and Monitor. Each of these roles has varying levels of fixed privilege to interact with the TSF. The Admin role is able to perform all security-relevant management functionality (such as user management, password policy configuration, application of software updates, and configuration of cryptographic settings). The Monitor role provides view-only access to ports and configurations. Therefore, the term “Admin”, used throughout this document, is considered to be a Security Administrator of the TSF. Management functions can be performed using the local CLI, remote CLI, or web GUI. All software updates to the TOE are performed manually. Protection of the TSF The TOE stores usernames and passwords in a password file that cannot be viewed by any user on the TOE regardless of the user's role. The passwords are hashed using SHA-512. Public keys are stored in the configuration database which is integrity checked at boot time. Key data is stored in plaintext on the hard drive but cannot be accessed by any user. The TOE has an underlying hardware clock that is used for keeping time. The time can be manually set by the administrator. Power-on self-tests are executed automatically when the FIPS validated cryptographic module is loaded into memory. The FIPS cryptographic module verifies its own integrity using an HMAC-SHA1 digest computed at build time. All binaries (e.g. executables, libraries), are located on a read-only partition and cannot be modified. In addition, the TOE has a configuration database that is integrity checked at boot time. The version of the TOE (both the currently executing version and the installed/updated version, if different) can be verified from any of the administrative interfaces provided by the TSF. The TOE is updated via the Gigamon Update Server or the local Update Server via an HTTPS protected connection. The updated image is verified via a digital signature. TOE Access The TOE can terminate inactive local console, remote CLI or web GUI sessions after a specified time period. The default setting is 15 minutes. Users can also terminate their own interactive sessions. Once a session has been terminated, the TOE requires the user to re-authenticate to establish a new session. The Security Target Gigamon GigaVUE 17 | P a g e TOE displays an administratively configured banner on the local console or remote CLI and the web GUI prior to allowing any administrative access to the TOE. Trusted Path/Channels The TOE connects and sends data to IT entities that reside in the Operational Environment via trusted channels. In the evaluated configuration, the TOE connects with a Syslog Server using SSH to encrypt the audit data that traverses the channel. The TOE also connects with an LDAP server using TLS and to an Update Server using TLS/HTTPS. The Update Server may either be one maintained by Gigamon, or a local server that is deployed in the TOE’s Operational Environment. When accessing the TOE remotely, administrators interface with the TSF using a trusted path. The remote CLI is protected via SSH and the web GUI is protected by TLS/HTTPS. 3 Conformance Claims 3.1 CC Version This ST is compliant with Common Criteria for Information Technology Security Evaluation, Version 3.1 Revision 4 September 2012. 3.2 CC Part 2 Conformance Claims This ST and Target of Evaluation (TOE) is Part 2 extended to include all applicable NIAP and International interpretations through August 21, 2018. 3.3 CC Part 3 Conformance Claims This ST and Target of Evaluation (TOE) are conformant to Part 3 to include all applicable NIAP and International interpretations through August 21, 2018. 3.4 PP Claims This ST claims exact conformance to the following Protection Profiles:  collaborative Protection Profile for Network Devices Version 2.0 + Errata 20180314 [NDcPP]  The following is the list of NIAP Technical Decisions that are applicable to the ST/TOE and a summary of their impact: TD # Title Changes Analysis to this evaluation SF R A A Notes NA Reason TD0343 NIT Technical Decision for Updating FCS_IPSEC_EXT.1.14 Tests X X Not claiming IPSEC TD0342 NIT Technical Decision for TLS and DTLS Server Tests X Security Target Gigamon GigaVUE 18 | P a g e TD0341 NIT Technical Decision for TLS wildcard checking X TD0340 NIT Technical Decision for Handling of the basicConstraints extension in CA and leaf certificates X TD0339 NIT Technical Decision for Making password-based authentication optional in FCS_SSHS_EXT.1.2 X X X TD0338 NIT Technical Decision for Access Banner Verification X TD0337 NIT Technical Decision for Selections in FCS_SSH*_EXT.1.6 X X X TD0336 NIT Technical Decision for Audit requirements for FCS_SSH*_EXT.1.8 X TD0335 NIT Technical Decision for FCS_DTLS Mandatory Cipher Suites X Not claiming DTLS but claiming TLSS.

Table 3-1: Technical Decisions Note that Technical Decisions were not considered to be applicable if any of the following conditions were true:  The Technical Decision does not apply to the NDcPP.  The Technical Decision does not apply to the current version of the NDcPP.  The Technical Decision applies to an SFR that was not claimed by the TOE.  The Technical Decision applies to an SFR selection or assignment that was not chosen for the TOE.  The Technical Decision only applies to one or more Application Notes in the NDcPP and does not affect the SFRs or how the evaluation of the TOE is conducted.  The Technical Decision is an affirmation that an existing requirement or Evaluation Activity is correct.  The Technical Decision was superseded by a more recent Technical Decision.  The Technical Decision is issued as guidance for future versions of the NDcPP. 3.5 Package Claims The TOE claims exact conformance to the NDcPP, which is conformant with CC Part 3. The TOE claims following Selection-Based SFRs that are defined in the appendices of the claimed PP:  FCS_HTTPS_EXT.1  FCS_SSHC_EXT.1  FCS_SSHS_EXT.1  FCS_TLSC_EXT.1  FCS_TLSS_EXT.1  FIA_X509_EXT.1/Rev  FIA_X509_EXT.2  FIA_X509_EXT.3 The TOE claims the following Optional SFRs that are defined in the appendices of the claimed PP:  FAU_STG.1  FMT_MTD.1/CryptoKeys This does not violate the notion of exact conformance because the cPP specifically indicates these as allowable selections and options and provides both the ST author and evaluation laboratory with instructions on how these claims are to be documented and evaluated. Security Target Gigamon GigaVUE 20 | P a g e 3.6 Package Name Conformant or Package Name Augmented This ST and TOE are in exact conformance with the NDcPP. 3.7 Conformance Claim Rationale The NDcPP states the following: “This is a Collaborative Protection Profile (cPP) whose Target of Evaluation (TOE) is a network device… A network device in the context of this cPP is a device composed of both hardware and software that is connected to the network and has an infrastructure within the network… Examples of network devices that are covered by requirements in this cPP include routers, firewalls, VPN gateways, IDSs, and switches.” The TOE is a network device composed of hardware and software that is designed to apply forwarding rules to different types of network traffic so that it can be analyzed by a variety of third-party tools. As such, it can be understood as having a role in network infrastructure. Therefore, the conformance claim is appropriate. Security Target Gigamon GigaVUE 21 | P a g e 4 Security Problem Definition 4.1 Threats This section identifies the threats against the TOE. These threats have been taken from the NDcPP. Threat Threat Definition T.UNAUTHORIZED_ADMINISTRATOR_ACCESS Threat agents may attempt to gain Administrator access to the network device by nefarious means such as masquerading as an Administrator to the device, masquerading as the device to an Administrator, replaying an administrative session (in its entirety, or selected portions), or performing man-in-the-middle attacks, which would provide access to the administrative session, or sessions between network devices. Successfully gaining Administrator access allows malicious actions that compromise the security functionality of the device and the network on which it resides. T.WEAK_CRYPTOGRAPHY Threat agents may exploit weak cryptographic algorithms or perform a cryptographic exhaust against the key space. Poorly chosen encryption algorithms, modes, and key sizes will allow attackers to compromise the algorithms, or brute force exhaust the key space and give them unauthorized access allowing them to read, manipulate and/or control the traffic with minimal effort. T.UNTRUSTED_COMMUNICATION_CHANNELS Threat agents may attempt to target network devices that do not use standardized secure tunneling protocols to protect the critical network traffic. Attackers may take advantage of poorly designed protocols or poor key management to successfully perform man-in-the-middle attacks, replay attacks, etc. Successful attacks will result in loss of confidentiality and integrity of the critical network traffic, and potentially could lead to a compromise of the network device itself. T.WEAK_AUTHENTICATION_ENDPOINTS Threat agents may take advantage of secure protocols that use weak methods to authenticate the endpoints – e.g. a shared password that is guessable or transported as plaintext. The consequences are the same as a poorly designed protocol, the attacker could masquerade as the Administrator or another device, and the attacker could insert themselves into the network stream and perform a man-in-the-middle attack. The result is the critical network traffic is exposed and there could be a loss of confidentiality and integrity, and potentially the network device itself could be compromised. T.UPDATE_COMPROMISE Threat agents may attempt to provide a compromised update of the software or firmware which undermines the security functionality of the device. Non-validated updates or updates validated using non-secure or weak cryptography leave the update firmware vulnerable to surreptitious alteration. Security Target Gigamon GigaVUE 22 | P a g e T.UNDETECTED_ACTIVITY Threat agents may attempt to access, change, and/or modify the security functionality of the network device without administrator awareness. This could result in the attacker finding an avenue (e.g., misconfiguration, flaw in the product) to compromise the device and the Administrator would have no knowledge that the device has been compromised. T.SECURITY_FUNCTIONALITY_COMPROMISE Threat agents may compromise credentials and device data enabling continued access to the network device and its critical data. The compromise of credentials includes replacing existing credentials with an attacker’s credentials, modifying existing credentials, or obtaining the Administrator or device credentials for use by the attacker. T.PASSWORD_CRACKING Threat agents may be able to take advantage of weak administrative passwords to gain privileged access to the device. Having privileged access to the device provides the attacker unfettered access to the network traffic, and may allow them to take advantage of any trust relationships with other network devices. T.SECURITY_FUNCTIONALITY_FAILURE An external, unauthorized entity could make use of failed or compromised security functionality and might therefore subsequently use or abuse security functions without prior authentication to access, change or modify device data, critical network traffic or security functionality of the device. Table 4-1: TOE Threats 4.2 Organizational Security Policies This section identifies the organizational security policies which are expected to be implemented by an organization that deploys the TOE. These policies have been taken from the NDcPP. Policy Policy Definition P.ACCESS_BANNER The TOE shall display an initial banner describing restrictions of use, legal agreements, or any other appropriate information to which users consent by accessing the TOE. Table 4-2: Organizational Security Policies 4.3 Assumptions The specific conditions listed in this section are assumed to exist in the TOE’s Operational Environment. These assumptions have been taken from the NDcPP. Assumption Assumption Definition A.PHYSICAL_PROTECTION The network device is assumed to be physically protected in its operational environment and not subject to physical attacks that compromise the security and/or interfere with the device’s physical interconnections and correct operation. This protection is assumed to be sufficient to protect the device and the data it contains. As a result, the cPP will not include any requirements on physical tamper protection or other physical attack mitigations. The cPP will not expect the product to defend against physical access to the device that allows unauthorized entities to extract data, bypass other controls, or otherwise manipulate the device. Security Target Gigamon GigaVUE 23 | P a g e A.LIMITED_FUNCTIONALITY The device is assumed to provide networking functionality as its core function and not provide functionality/services that could be deemed as general purpose computing. For example, the device should not provide a computing platform for general purpose applications (unrelated to networking functionality). A.NO_THRU_TRAFFIC_ PROTECTION A standard/generic network device does not provide any assurance regarding the protection of traffic that traverses it. The intent is for the network device to protect data that originates on or is destined to the device itself, to include administrative data and audit data. Traffic that is traversing the network device, destined for another network entity, is not covered by the NDcPP. It is assumed that this protection will be covered by cPPs for particular types of network devices (e.g., firewall). A.TRUSTED_ADMINISTRATOR The Security Administrator(s) for the network device are assumed to be trusted and to act in the best interest of security for the organization. This includes being appropriately trained, following policy, and adhering to guidance documentation. Administrators are trusted to ensure passwords/credentials have sufficient strength and entropy and to lack malicious intent when administering the device. The network device is not expected to be capable of defending against a malicious Administrator that actively works to bypass or compromise the security of the device. A.REGULAR_UPDATES The network device firmware and software is assumed to be updated by an Administrator on a regular basis in response to the release of product updates due to known vulnerabilities. A.ADMIN_CREDENTIALS_ SECURE The Administrator’s credentials (private key) used to access the network device are protected by the platform on which they reside. A.RESIDUAL_INFORMATION The Administrator must ensure that there is no unauthorized access possible for sensitive residual information (e.g. cryptographic keys, keying material, PINs, passwords etc.) on networking equipment when the equipment is discarded or removed from its operational environment. Table 4-3: TOE Assumptions 4.4 Security Objectives This section identifies the security objectives of the TOE and its supporting environment. The security objectives identify the responsibilities of the TOE and its environment in meeting the security needs. TOE Security Objectives The NDcPP does not define any security objectives for the TOE. Security Objectives for the Operational Environment The TOE’s operational environment must satisfy the following objectives: Objective Objective Definition OE.ADMIN_CREDENTIALS_SECURE The Administrator’s credentials (private key) used to access the TOE must be protected on any other platform on which they reside. OE.NO_GENERAL_PURPOSE There are no general-purpose computing capabilities (e.g., compilers or user applications) available on the TOE, other than those services necessary for the operation, administration and support of the TOE. OE.NO_THRU_TRAFFIC_PROTECTION The TOE does not provide any protection of traffic that traverses it. It is assumed that protection of this traffic will be covered by Security Target Gigamon GigaVUE 24 | P a g e other security and assurance measures in the operational environment. OE.PHYSICAL Physical security, commensurate with the value of the TOE and the data it contains, is provided by the environment. OE.RESIDUAL_INFORMATION The Security Administrator ensures that there is no unauthorized access possible for sensitive residual information (e.g. cryptographic keys, keying material, PINs, passwords etc.) on networking equipment when the equipment is discarded or removed from its operational environment. OE.TRUSTED_ADMIN Security Administrators are trusted to follow and apply all guidance documentation in a trusted manner. OE.UPDATES The TOE firmware and software is updated by an Administrator on a regular basis in response to the release of product updates due to known vulnerabilities. Table 4-4: Operational Environment Objectives 4.5 Security Problem Definition Rationale The assumptions, threats, OSPs, and objectives that are defined in this ST represent the assumptions, threats, OSPs, and objectives that are specified in the Protection Profile to which the TOE claims conformance. Security Target Gigamon GigaVUE 25 | P a g e 5 Extended Components Definition 5.1 Extended Security Functional Requirements The extended Security Functional Requirements that are claimed in this ST are taken directly from the PP to which the ST and TOE claim conformance. These extended components are formally defined in the PP in which their usage is required. 5.2 Extended Security Assurance Requirements There are no extended Security Assurance Requirements in this ST. Security Target Gigamon GigaVUE 26 | P a g e 6 Security Functional Requirements 6.1 Conventions The CC permits four functional component operations—assignment, refinement, selection, and iteration—to be performed on functional requirements. This ST will highlight the operations in the following manner:  Assignment: allows the specification of an identified parameter. Indicated with italicized text.  Refinement: allows the addition of details. Indicated with bold text. Note that conversion of British spelling to American spelling is not marked as a refinement (e.g. ‘authorisation’ changed to ‘authorization’).  Selection: allows the specification of one or more elements from a list. Indicated with underlined text.  Iteration: allows a component to be used more than once with varying operations. Indicated with a sequential number in parentheses following the element number of the iterated SFR and/or separated by a “/” with a notation that references the function for which the iteration is used, e.g. “/TrustedUpdate” for an SFR that relates to update functionality When multiple operations are combined, such as an assignment that is provided as an option within a selection or refinement, a combination of the text formatting is used. If SFR text is reproduced verbatim from text that was formatted in a claimed PP (such as if the PP’s instantiation of the SFR has a refinement or a completed assignment), the formatting is not preserved.

Security Target Gigamon GigaVUE 46 | P a g e 8 TOE Summary Specification The following sections identify the security functions of the TOE and describe how the TSF meets each claimed SFR. They include Security Audit, Cryptographic Support, Identification and Authentication, Security Management, Protection of the TSF, TOE Access, and Trusted Path/Channels. 8.1 Security Audit FAU_GEN.1: The TOE contains mechanisms to generate audit data based upon successful and unsuccessful management actions by all authorized users of the TOE. Each audit record contains identifying information of the subject performing the action. The audit records are generated and stored in the form of syslog records which are sent securely to the Syslog Server protected by SSHv2. The TOE maintains log levels which determine the set of events that are logged. The log level is set using the following command: logging level. Setting the log-level to “info” captures all the necessary logs defined in the NDcPP. The TOE allows viewing of the audit records through the local console with the following command: show log. Users of any role can view audit log files, however, only Admin users can delete audit log files. If an Admin deletes a log file, an audit record of that action is also recorded. Table 9-1 in Appendix A lists the auditable events defined by this component and examples of audit records for that particular event. The audit records that the TOE creates include the following information: date and time of the event, event type, subject identity, success or failure of the event, and source of the event. FAU_GEN.2: The TOE records the identity of the user (e.g. username, system name, IP address) associated with each audited event in the audit record. FAU_STG.1: The TOE allows viewing of the audit records through the CLI with the following command: show log. Users of any role can view audit log files, however, only Admin users can delete audit log files. No modification of log files is permitted, regardless of role. If an Admin deletes a log file, an audit record of that action is also recorded. The TOE allocates up to 8MB for the audit log but rolls this data over to a backup file and compresses it once full. A maximum of 8 backup files exist, and the oldest one is deleted as part of a rollover process when a new backup is created. FAU_STG_EXT.1: In the evaluated configuration, the TOE will send audit records to a remote Syslog Server via an encrypted SSH channel over the Ethernet Management Port. When the Syslog Server is configured, the audit records are stored locally and immediately pushed to the Syslog Server. If Syslog Server connectivity is unavailable, audit records will only be stored locally. Upon re-establishment of communications with the Syslog Server, new audit records will resume being transmitted to it but the Security Target Gigamon GigaVUE 47 | P a g e audit records that were generated during the time the Syslog Server connection was down remain stored locally and are not sent to the Syslog Server. New audit records are stored locally on the TOE under the /var/log directory in the file named “messages". The "message" file is archived when it reaches a specific size (8MB) by compressing it and saving the file as "messages.1.gz”. Meanwhile, a new "messages" file is created for new audit records and the other compressed messages files are rotated so that the 8 most recent compressed messages files are saved. The 8 compressed files are named "messages.1.gz”, “messages2.gz”, and so on. Therefore, as part of the file rotation “messages8.gz” will be deleted, "messages.7.gz" will be saved as "messages.8.gz", "messages.6.gz" will be saved as "messages.7.gz", and so on until the "messages" file is compressed into "messages.1.gz”. This mechanism guarantees a maximum limit of disk usage used by the log files. Only a user with the Admin role can delete the log files. Users with the Admin role are considered trusted users and are not expected to delete the audit records. 8.2 Cryptographic Support FCS_CKM.1: The TOE generates ECC keys using NIST curve P-256, in accordance with FIPS PUB 186-4. The ECC keys are generated in support of device authentication. Also, the TOE uses finite field cryptography (FFC) Diffie-Hellman group 14 key with key size of 2048 bits that meet the following: RFC 3526 Section 3. These keys are used for SSH and TLS key establishment. The TOE’s key generation function is validated under CAVP ECDSA certificate: #1492. FCS_CKM.2: The TOE implements NIST SP 800-56A Revision 2 conformant key establishment mechanisms for Elliptic Curve Diffie-Hellman (ECDH) key establishment schemes. Specifically, the TOE complies with the NIST SP 800-56A Revision 2 key agreement scheme (KAS) primitives that are defined in section 5.6 of the SP. This is used for the establishment of TLS sessions, for which the TOE can act as both a sender and a receiver. In addition, the TOE implements Diffie-Hellman group 14 with key size of 2048 bits for SSH key establishment, for which the TOE can also be both a sender and a receiver. The group, prime, hexadecimal value, and generator are all consistent with RFC 3526, section 3. The TOE’s implementation of NIST SP 800-56A Revision 2 is validated under CAVP CVL certificate #1981. FCS_CKM.4: The TOE implements secure key destruction as follows:  Keys stored in volatile memory: These keys are immediately zeroized using the function memset() upon deallocation. These keys are destroyed when sessions are closed.  Keys stored in non-volatile memory: The TOE zeroizes all plaintext secret and private cryptographic keys in persistent storage by overwriting the file with zeroes and performing a read verify. Upon successful completion of the zeroization, the file is deallocated using the Security Target Gigamon GigaVUE 48 | P a g e file system API unlink(). These keys are destroyed during import/re-installation or upgrade/regeneration. The TOE is not subject to any situations that would prevent or delay key destruction and strictly conforms to the key destruction requirements. This combined approach protects the keys in volatile and non-volatile memory from being compromised. The following table identifies the 0keys and CSPs that are applicable to the TOE as well as their usage, storage location, and method of destruction: Key Material Origin Storage Location Clearing of Key Material SSH keys SSH server/ client application Non-volatile storage/file system Upon regeneration of keys. Authentication keys X.509 certificates Non-volatile storage/ file system Upon import/creation of configuration DB on installation or upgrade. TLS session keys syslogtls, radsec applications RAM Non-volatile storage For RAM: Destroyed on close of session For non-volatile storage, Upon regeneration of keys. Table 8-1: Cryptographic Materials, Storage, and Destruction Methods FCS_COP.1/DataEncryption: The TOE performs encryption and decryption using the AES algorithm in CBC mode with key sizes of 128 and 256 bits. This algorithm implementation is validated under CAVP AES certificate #5541. The AES algorithm meets ISO/IEC 18033-3 and the CBC mode implementation meets ISO/IEC 10116. FCS_COP.1/SigGen: The TOE performs signature generation and validation using Elliptic Curve Digital Signature Algorithm (ECDSA). The TOE supports ECDSA with 256 bit key size and implements the NIST P-256 curve. The ECDSA implementation meets ISO/IEC 14888-3 Section 6.4 and FIPS 186-4. This implementation is validated under CAVP ECSDA certificate #1492. FCS_COP.1/Hash: The TOE provides cryptographic hashing services using SHA-1, SHA-256, and SHA-512 with message digest sizes of 160, 256, and 512 bits respectively, as specified in FIPS PUB 186-4. The TSF uses hashing services the following functions:  SHA-1, SHA-256, and SHA-512 for SSH data integrity  SHA-1 for software integrity  SHA-1 for TLS  SHA-1 for digital signature  SHA-512 for password hashing The SHA algorithm meets ISO/IEC 10118-3:2004 and is validated under CAVP SHS certificate #4447. Security Target Gigamon GigaVUE 49 | P a g e FCS_COP.1/KeyedHash: The TOE provides keyed-hashing message authentication services using HMAC-SHA-1, HMAC-SHA- 256, and HMAC-SHA-512. The HMAC implementation supports key sizes that are equal to block sizes. HMAC is implemented as specified in FIPS PUB 198-1 and FIPS PUB 180-3, and the following MAC sizes are supported:  HMAC-SHA-1: 10, 12, 16, 20 bytes.  HMAC-SHA-256: 16, 24, 32 bytes.  HMAC-SHA-512: 32, 40, 48, 56, 64 bytes. The algorithm meets ISO/IEC 9797-2:2011 Section 7 and is validated under CAVP HMAC certificate #3692. FCS_HTTPS_EXT.1: The TOE implements HTTPS in order to facilitate remote administration over the web GUI and to download software updates from an HTTPS server in the Operational Environment. The HTTPS implementation conforms to RFC 2818 and uses the TLS client/server implementations specified in FCS_TLSC_EXT.1 and FCS_TLSS_EXT.1. Since the HTTPS server does not enforce TLS mutual authentication, the only prerequisite to establishment of a TLS connection is that the peer initiate the communications. FCS_RBG_EXT.1: The TOE implements a NIST-approved deterministic random bit generator (DRBG). The DRBG used by the TOE is the CTR_DRBG with AES as specified by ISO/IEC 18031:2011. The TOE models uniformly provide two software-based entropy sources as described in the proprietary entropy specification. The DRBG is seeded with a minimum of 256 bits of entropy so that it is sufficient to ensure full entropy for 256-bit keys, which are the largest keys generated by the TSF. The TOE’s DRBG implementation meets ISO/IEC 18031:2011 and is validated under CAVP certificate #2196. FCS_SSHC_EXT.1/ FCS_SSHS_EXT.1: SSHv2 is used to secure the remote CLI management connection (SSH Server) and Syslog connection (SSH Client) between the TOE and a remote Syslog Server The traffic for both of these connections is sent via the Ethernet Management Port and by default, the SSHv2 port used is port 22. The TOE implements the SSHv2 protocol that complies with the following RFCs: 4251, 4252, 4253, 4254, 5656, and 6668. The TOE supports password based and public key based authentication methods as described in RFC 4252; both authentication methods are supported on the remote CLI but only public key based authentication is used when communicating with the remote Syslog Server. The TOE implements public key authentication using ecdsa-sha2-nistp256. Per RFC 4251 section 4.1, the TOE’s SSH client implementation will authenticate the identity of the Syslog Server (i.e. SSH server) by using its local database (i.e. /.ssh/knownhosts) which associates each host name with its corresponding public key. Session keys are created when the TOE establishes an SSHv2 connection. The TOE will monitor the time period during which the SSHv2 session keys are active and how much data has been transmitted using them. The TOE has been hard coded to initiate a rekey when the session keys have been used for one hour Security Target Gigamon GigaVUE 50 | P a g e (3600 seconds) or when 256 MB of data has been transmitted when TOE acts as a client and 1 GB when the TOE acts as a server. Rekeying is performed upon reaching the threshold that is hit first. Regardless of whether the TOE is acting as an SSH client or server, all SSHv2 connections will be dropped upon detection of any packet greater than 65535 bytes being transported, as described in RFC 4253. Data encryption is provided by the AES-CBC-128 and AES-CBC-256 encryption algorithms, ecdsa-sha2-nistp256 is used for the public key algorithm, and HMAC-SHA1, HMAC-SHA2-256, and HMAC-SHA2-512 are used for the data integrity algorithms. The key exchange method used in SSHv2 is Diffie-Hellman group 14 with SHA-1. The SSH public/private key pairs are generated using the following command: ssh server host-key generate The TOE has an “Secure Cryptography Mode” to limit the SSH connection parameters to those defined in the evaluated configuration. FCS_TLSC_EXT.1/FCS_TLSS_EXT.1: The TOE uses the TLS 1.2 protocol to secure the following connections and channels: web GUI management interface connection using HTTPS (TLS Server), Gigamon Update Server or local Update Server connections using HTTPS (TLS Client) used for TOE image updates, and LDAP server connection (TLS Client) used for authentication requests. When the TOE is operating in “Secure Cryptography Mode”, TLS uses the following ciphersuites:  TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA as defined in RFC 4492  TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA as defined in RFC 4492  TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 as defined in RFC 5289  TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384 as defined in RFC 5289 When the TOE uses TLS client functionality, the presented identifier for the server certificate has to match the reference identifier in order to establish the connection. The hostname reference identifier is the only supported value for the LDAP and update server interface. Regardless of the external interface, wildcards cannot be used when defining the reference identifier on the TOE. The only Supported Elliptic Curves Extension included in the Client Hello is the NIST curve secp256r1. This is not configurable. Certificate pinning is not supported. When certificate validation fails, the connection is not established. When the TOE uses TLS server functionality, it will reject all connection attempts from TLS versions other than 1.2. EC Diffie-Hellman parameters are generated over NIST curves secp256r1. 8.3 Identification and Authentication FIA_AFL.1: The TSF provides a configurable counter for consecutive failed authentication attempts that will lock a user account when the failure counter threshold is reached. When an account is locked a user cannot login to either the CLI or web GUI interface. A valid login that happens prior to the failure counter reaching its threshold will reset the counter to zero. The CLI counter can be set to any 32-bit integer value (a value of 0 will disable lockout). While the user account is locked, no authentication is possible. The authentication failure settings can be configured such Security Target Gigamon GigaVUE 51 | P a g e that the default ‘admin’ user account overrides this functionality (exempt) so that it is not possible to cause a denial of service. The lockout duration is a configurable number of seconds, with a default setting of 360. FIA_PMG_EXT.1: Passwords maintained by the TSF can be composed using any combination of upper case and lower case letters, numbers, and special characters including the following: “!”,”@”,”#”,”$”,”%”,”^”,”&”,”*”,”(“,”)”. The password policy is configurable by the Admin and supports the minimum password length of 8 characters and a maximum password length of 30 characters. FIA_UAU.7: While authenticating locally to the TOE, the user’s password does not appear in the password field. Instead, asterisks will appear thus masking the password to prevent the password from being shared. In the case that a user enters invalid credentials (valid/invalid username or valid/invalid password), the TOE does not reveal any information about the invalid component of the credential. FIA_UAU_EXT.2: Users can authenticate to the TOE locally or remotely. Local users log in to the local console using a username and password via the Serial Port. Remote users can log in to the TOE via the remote CLI using username and password or SSH public key via the Ethernet Management Port. User authentication information that is sent remotely via the remote CLI is protected using SSHv2. Users may also authenticate remotely via a web GUI that is protected using TLS/HTTPS via the Ethernet Management Port. When authenticating using username and password, these credentials are verified using either the TOE's local mechanism and credential repository or by an LDAP server that provides external authentication decisions. For external authentication decisions, the TOE sends an authentication request to the LDAP server which will verify the credentials against the LDAP server's directory and will provide an authentication decision back to the TOE, which is subsequently enforced. The connection between the TOE and the LDAP server is protected by TLS v1.2. When public key authentication is used, the TOE authenticates users by verifying the message the TOE receives from the SSH client using the message's associated public key stored on the TOE. FIA_UIA_EXT.1: In the evaluated configuration, the warning banner is displayed prior to the user authenticating to the TOE via the local console, the remote CLI, or the web GUI. The display of the warning banner is the only service that can be run prior to authentication and thus, the TOE does not allow a user to perform any other actions prior to authentication, regardless of the interface used. FIA_X509_EXT.1/ FIA_X509_EXT.2/ FIA_X509_EXT.3: The TOE performs certificate validity checking for outbound TLS/HTTPS connections to the Update Server and LDAP Server. In addition to the validity checking that is performed by the TOE, the TSF will validate certificate revocation status using a certificate revocation list (CRL) that the TSF is configured to download Security Target Gigamon GigaVUE 52 | P a g e automatically from a Certification Authority in the Operational Environment. In the event that the revocation status cannot be verified, the certificate will not be accepted. The TSF determines the validity of certificates by ensuring that the certificate and the certificate path are valid in accordance with RFC 5280. In addition, the certificate path is terminated in a trusted CA certificate, the basicConstraints extension is present, and the CA flag is set to TRUE for all CA certificates. The TSF also ensures that the extendedKeyUsage field includes the correct purpose for its intended use. This includes Server Authentication for TLS server certificates; the TSF does not handle TLS client certificates, certificates associated with OCSP responses, or code signing certificates. In order to support TLS/HTTPS connectivity over the web GUI, the TSF provides the ability to generate a Certificate Request Message as specified by RFC 2986 so that its server certificate can be signed by a Certification Authority. The message includes public key, Common Name, Organization, Organizational Unit, and Country values. The certificate chain of the Certificate Response is validated by the TSF prior to being installed as the TOE’s server certificate. 8.4 Security Management FMT_MOF.1/ManualUpdate: TOE software updates reside on a web server in the Operational Environment. This may be a server maintained by Gigamon or a server within the organization that deploys the TOE. Regardless of where the update resides, it is loaded onto the TOE and applied manually. The Monitor role provides view-only access to ports and configurations. The Admin role is the only administrative role that can perform this action. The TSF restricts the access to this function by enforcing the GigaVUE's role-based access control system. FMT_MTD.1/CoreData: GigaVUE provides two user roles: Admin and Monitor. The TSF uses role-based access control to assign each user account to one or more roles, each of which has a fixed set of privileges to interact with the product. Of these roles, only the Admin role is authorized to perform the management functions associated with the TSF. The Monitor role provides view-only access to ports and configurations. The Admin role is therefore functionally identical to the ‘Security Administrator’ as defined by the NDcPP. The only security-relevant TOE functionality that is available to a user prior to authentication is the display of the warning banner. FMT_MTD.1/CryptoKeys: The Admin role is the only role that is permitted to manipulate cryptographic data on the TOE. Within the TSF, this behavior is limited to the generation and import/removal of X.509 certificates. FMT_SMF.1: A user with the Admin role is capable of performing management functions on the TOE locally and remotely. Admins can perform management functions via the local console or remotely via the remote CLI or web GUI. The following table lists the TSF management functions and identifies the interface(s) that can be used to perform them: Security Target Gigamon GigaVUE 53 | P a g e Management Function Local CLI Remote CLI Remote GUI View Audit Data X X Delete Audit Log X X Configure TLS Connection Parameters X X X Configure SSH Connection Parameters X X X Configure Failed Lockout Threshold X X X Configure Lockout Duration X X X Create Users X X X Modify User Passwords X X X Modify Password Policy X X X Configure Supported Authentication Mechanism X X X Generate X.509 Certificate Request Message X X Initiate Manual Update X X X Configure System Time X X X Configure Idle Session Timeout X X X Configure Banner Text X X X Table 8-2: Management Functions by Interface An Admin can modify the text displayed in the TOE's login banners, set the values for session inactivity before termination, and initiate manual updates to the TOE's software after verifying the digital signature of the update. The Admin is also able to configure the TOE’s cryptographic functionality. This is accomplished by entering a command into the CLI which places the TOE into "Secure Cryptography Mode" of operation. When this command is entered, the TOE limits the cryptographic algorithms to meet the requirements defined within the Security Target. FMT_SMR.2: The security management functions available to authorized users of the TOE are mediated by a role-based access control system. The role-based access control system is enforced via the local console and remotely via the remote CLI or web GUI. The TOE has two roles: Admin and Monitor. Each role has different authorizations in terms of the functions that they can perform. All SFR relevant management activity is performed by the Admin, role which corresponds to the NDcPP’s definition of Security Administrator. Only users with the Admin role are permitted to create and assign roles to users. The Monitor role provides view-only access to ports and configurations. Each user has the following security attributes associated with them:  Username  Password  SSH public key (optional - used for remote CLI login only)  One or more roles The username and password are for authenticating to the TOE. These credentials are verified using the authentication mechanism that has been configured for the TOE. Once the username has been validated, the username is used to query the one or more roles which have been associated with that username Security Target Gigamon GigaVUE 54 | P a g e within the TOE's local store. The TOE then uses the roles assigned to the authenticated user to determine if an action is authorized per GigaVUE's role-based access control system. When LDAP authentication is used, that user information is mapped to the internally-stored attributes so that the authentication event is associated with the correct user. 8.5 Protection of the TSF FPT_APW_EXT.1: The TOE stores usernames and passwords in a password file. All passwords stored on the TOE are stored in hashed form using SHA-512. The password file cannot be viewed by any user on the TOE regardless of the user's role. FPT_SKP_EXT.1: Public keys are stored in the configuration database which is integrity checked at boot time. Secret/private key data is stored in plaintext on the hard drive but cannot be accessed via the local console, remote CLI, or the web GUI by any user. FPT_STM_EXT.1: The TOE has an underlying hardware clock that is used for keeping time. A user with the Admin role can set the clock’s time manually. The TSF uses time data for the following purposes:  Audit record timestamps  Inactivity timeout for administrative sessions  Expiration checking for certificates FPT_TST_EXT.1: All binaries (e.g. executables, libraries), are located on a read-only partition and cannot be modified. In addition, the TOE has a configuration database that is integrity checked at boot time using SHA-1. The udiag is run under u-boot (microcode boot loader) which runs power-on self-tests of all the major components (e.g., memory, CPU, UART, Ethernet controllers) on the motherboard, including the components that connect to the i2c buses. This includes all transceivers used by the data plane. The pci_diag component is a Linux component that runs when the kernel is loading that is responsible for testing and checking the components connected to the PCIe interfaces. It is also responsible for Line card type detection. Once booted, the TSF will execute a continuous RNG test in order to ensure that the entropy source has not degraded. If any of the integrity tests fail, diagnostic information is displayed on the boot console indicating what the problem is. For example: POST Failed Power-up self test failed cryptographic algorithm test failed. Security Target Gigamon GigaVUE 55 | P a g e When integrity test fails the TOE is put into safe mode (Gigamon specific state). In safe mode, the device will operate in a limited manner which requires user intervention to bring the appliance back into a normal state after fixing the issues. The console display clearly indicates that the appliance is in safe mode along with the diagnostic information. These tests are sufficient to validate the correct operation of the TSF because they verify that the cryptographic module is operating correctly, the configuration database does an integrity check, and that the underlying hardware does not have any anomalies that would cause the software to be executed in an unpredictable or inconsistent manner. FPT_TUD_EXT.1: TOE Admin users can query the current executing version and the most recently installed version of the TOE's firmware/software on the local console, remote CLI interface, and the web GUI interface. On the local console and remote CLI interface a user can enter the “show version” command to show both versions of the TOE's firmware/software. Within the web GUI interface, the user can navigate to the "Reboot and Upgrade" tab where both versions of the TOE's firmware/software will be visible. In order to update the TOE, the Admin can point the TOE directly to the Gigamon Update Server which is a Gigamon hosted site and enter a username and password to download the image. Alternatively, the Admin can download the image themselves and host it on a local server. The Gigamon Update Server is configured to secure the connection using TLS/HTTPS. In the evaluated configuration, any local server used to host the update will also be configured in this manner. The image that is downloaded is compressed and stored in a tar file and signed with a digital signature. All GigaVUEs are pre-loaded with a key for the signature verification performed as part of the update mechanism. Before the actual installation occurs, the signature is verified against the stored key. The image will not be installed if the update fails to be verified. If the signature is successfully verified, the update will be installed on the inactive partition. If the inactive partition already has a software version installed, the update will over-write the previously installed software. Once the new software is installed, the Admin will enter a command in the local console or remote CLI in order to boot off from the Inactive partition on which the updated was installed, thus making it the active partition. 8.6 TOE Access FTA_SSL_EXT.1: The TOE is designed to terminate a local session after a specific period of time. The default setting is 15 minutes and it is configurable by an Admin. Once a session has been terminated, the local user must re- authenticate to start a new session. FTA_SSL.3: The TOE can be configured to terminate remote interactive sessions that are inactive in two different ways. In the event that the inactivity setting is met while users are logged into the CLI, the TOE tears down the SSH connection. This setting can be configured to 0 or between .25-35791 minutes. The value of 0 means that this setting is disabled and there is no timeout configured. In the event that the inactivity setting is reached while a user is logged into the web GUI, the user’s session will end. This setting can be Security Target Gigamon GigaVUE 56 | P a g e configured between 0-525600 minutes. The value of 0 means that this setting is disabled and there is no timeout configured. The Admin users authenticated to the local console or remote CLI may configure this setting for all of the local console, remote CLI, and web GUI. However, Admin users authenticated to the web GUI can only configure the timeout setting for the web GUI. FTA_SSL.4: An Admin is able to terminate their own session by entering the "exit" command when logged into the local console or remote CLI. An Admin can terminate their own session by clicking on the "Logout" tab when logged into the web GUI. FTA_TAB.1: There are three possible ways to authenticate to the TOE: local console, remote CLI, and web GUI. Each of these interfaces has a configurable login banner that is displayed prior to the user authenticating to the TOE. The banner is configured using the “banner login-local” command for the local console and “banner login-remote” for both the remote CLI and web GUI. The command “banner login” configures the banner for all login methods. 8.7 Trusted Path/Channels FTP_ITC.1: The TOE connects and sends data to IT entities that reside in the Operational Environment via trusted channels. In the evaluated configuration, the TOE connects with a Syslog Server using SSHv2 to encrypt the audit data that traverses the channel. When remote authentication is configured, the TOE connects to an LDAP Server using TLS v1.2 to send authentication requests for a user attempting to login to the local console, remote CLI, or web GUI. The TOE can also connect to the Gigamon Update Server or a local Update Server using TLS/HTTPS (TLS v1.2) to download TOE software updates. The remote endpoints are authenticated using TLS server certificates and SSH host keys. In each of these instances, the TOE initiates communication as the client using the cryptographic protocol in the manner described by their respective SFRs. These protocols are used to protect the data traversing the channel from disclosure and/or modification. FTP_TRP.1/Admin: The Admin users are required to authenticate to the TOE in order to be able to perform any management functions. By initiating the trusted path via the web GUI or remote CLI, Admin users can perform management activities remotely.

Peer Certificate not authenticated Dec 14 17:28:35 gigamonTA100 mgmtd[874]: [mgmtd.NOTICE]: Exit with code 60 from curl: CApath: /var/opt/tms/output/cacerts curl: (60) Peer certificate cannot be authenticated with known CA certificates More details here: http://curl.haxx.se/docs/sslcerts.html curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn't adequate, you can specify an alternate file using the -- cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use the - k (or --insecure) option.
