1. Security Target Introduction
This section identifies the Security Target (ST) and Target of Evaluation (TOE) identification, ST conventions, ST
conformance claims, and the ST organization. The TOE is the Ruckus FastIron ICX Series Switch/Router 9.0.10
provided by CommScope Technologies LLC. The TOE is being evaluated as a network device.
The Security Target contains the following additional sections:
• Conformance Claims (Section 2)
• Security Objectives (Section 3)
• Extended Components Definition (Section 4)
• Security Requirements (Section 5)
• TOE Summary Specification (Section 6)
Conventions
The following conventions have been applied in this document:
• Security Functional Requirements – Part 2 of the CC defines the approved set of operations that may be
applied to functional requirements: iteration, assignment, selection, and refinement.
o Iteration: allows a component to be used more than once with varying operations. In the ST,
iteration is indicated by a parenthetical number placed at the end of the component. For example
FDP_ACC.1(1) and FDP_ACC.1(2) indicate that the ST includes two iterations of the
FDP_ACC.1 requirement.
o Assignment: allows the specification of an identified parameter. Assignments are indicated using
bold and are surrounded by brackets (e.g., [assignment]). Note that an assignment within a
selection would be identified in italics and with embedded bold brackets (e.g., [[selected-
assignment]]).
o Selection: allows the specification of one or more elements from a list. Selections are indicated
using bold italics and are surrounded by brackets (e.g., [selection]).
o Refinement: allows the addition of details. Refinements are indicated using bold, for additions,
and strike-through, for deletions (e.g., “… all objects …” or “… some big things …”).
• Other sections of the ST – Other sections of the ST use bolding to highlight text of special interest, such as
captions.

1.3 TOE Overview
The Target of Evaluation (TOE) is the Ruckus FastIron ICX Series Switch/Router 09.0.10 family of products.
The TOE is composed of a hardware appliance with embedded software installed on a management processor. The
software controls the switching and routing network frames and packets among the connections available on the
hardware appliances.
All TOE appliances are configured at the factory with default parameters to allow immediate use of the system’s basic
features through its Command Line Interface (CLI). However, the product should be configured in accordance with
the evaluated configuration (using the Ruckus FastIron FIPS and Common Criteria Configuration Guide) prior to
being placed into operation. The CLI is a text based interface which is accessible from a directly connected terminal
or via a remote terminal using SSH. This remote management interface is protected using encryption as explained
later in this ST.
The hardware platforms that support the TOE have a number of common hardware characteristics:
• Central processor that supports all system operations
• Dynamic memory, used by the central processor for all system operations
• Flash memory, used to store the operating system image
• Non-volatile memory, which stores configuration parameters used to initialize the system
at system startup
• Multiple physical network interfaces either fixed in configuration or removable as in a
chassis based product
1.4 TOE Description
The Target of Evaluation (TOE) is the Ruckus FastIron ICX Series Switch/Router 09.0.10 including the following
series and models:
a. ICX7150-C12P‐2X10GR‐A
b. ICX7150‐24‐4X10GR‐A
c. ICX7150‐24P‐4X10GR‐A
d. ICX7150‐48‐4X10GR‐A
e. ICX7150‐48P‐4X10GR‐A
f. ICX7150‐48PF‐4X10GR‐A
g. ICX7150‐48ZP‐8X10GR2‐A
h. ICX7250‐24G
i. ICX7250-48P
j. ICX7450-24P
k. ICX7450-48P
l. ICX7450-48F
While there are different models, they differ primarily in physical form factor, number and types of connections and
slots, and relative performance. The ICX Series possesses between 12 and 48 10/100/1000 Mbps RJ-45 ports, and
the presence of “F” in the model number indicates 100/1000 Mbps SFP ports instead of RJ-45 ports and the presence
of “P” indicates that the RJ-45 ports are PoE+. While there are some functional differences among the families, they
each provide the same security characteristics as claimed in this security target.
FastIron ICX 9.0.10 Security Target Version 1.1, 06/23/2022
Page 5 of 32
All 3 series have the following CPU: Dual-core ARM Cortex A9 1GHz (ARMv7-A architecture)
The TOE utilizes the Firmware crypto library referred to as the RUCKUS-IP-CRYPTO-VER-5.0 running on this
processor.
1.4.1 TOE Architecture
The basic architecture of each TOE appliance begins with a hardware appliance with physical network connections.
Within the hardware appliance, the IOS is designed to control and enable access to the available hardware functions
(e.g., program execution, device access, facilitate basic routing and switching functions). IOS enforces applicable
security policies on network information flowing through the hardware appliance.
During normal operation, IP packets are sent to the management IP address or through the appliance over one or more
of its physical network interfaces, which processes them according to the system’s configuration and state information
dynamically maintained by the appliance. This processing typically results in the frames or packets being forwarded
out of the device over another interface.
1.4.1.1 Physical Boundaries
Each TOE appliance has physical network connections to its environment to facilitate routing and switching of
network traffic. The TOE appliance can also be the destination of network traffic, where it provides interfaces for its
own management.
The TOE may be accessed and managed through a PC or terminal in an environment which can be remote from or
directly connected to the TOE.
The TOE can be configured to forward its audit records to an external syslog server in the network environment.
This is generally advisable given the limited audit log storage space on the evaluated appliances.
The use a RADIUS authentication server is included the evaluated configuration with communication occurring
over a protected channel.
The TOE can be configured to use an NTP server for network time or it can use its own hardware clock.
1.4.1.2 Logical Boundaries
This section summarizes the security functions provided by Ruckus FastIron ICX Series Switch/Router 9.0.10:
- Security audit
- Cryptographic support
- Identification and authentication
- Security management
- Protection of the TSF
- TOE access
- Trusted path/channels
Security audit
The TOE is able to generate logs for a wide range of security relevant events. The TOE can be configured to store
the logs locally so they can be accessed by an administrator and also to send the logs to a designated log server using
TLS to protect the logs while in transit on the network.
Cryptographic support
The TOE contains a CAVP-tested cryptographic module that provides key management, random bit generation,
encryption/decryption, digital signature and secure hashing and key-hashing features in support of higher-level
FastIron ICX 9.0.10 Security Target Version 1.1, 06/23/2022
Page 6 of 32
cryptographic protocols including SSH and TLS. The TOE supports SHA1 message digest authentication for NTP
servers.
Identification and authentication
The TOE requires users to be identified and authenticated before they can use functions mediated by the TOE, with
the exception of passing network traffic in accordance with its configured switching/routing rules. It provides the
ability to both assign attributes (user names, passwords and privilege levels) and to authenticate users against these
attributes.
Security management
The TOE provides Command Line Interface (CLI) commands to access the wide range of security management
functions to manage its security policies. All administrative activity and functions including security management
commands are limited to authorized users (i.e., administrators) only after they have provided acceptable user
identification and authentication data to the TOE. The security management functions are controlled through the use
of privileges associated with roles that can be assigned to TOE users. Among the available privileges, only the Super
User can actually manage the security policies provided by the TOE and the TOE offers a complete set of functions
to facilitate effective management since the Super User allows for complete read-and-write access to the system.
Protection of the TSF
The TOE implements a number of features to protect itself to ensure the reliability and integrity of its security
features.
It protects particularly sensitive data such as stored passwords and cryptographic keys so that they are not accessible
even by an administrator. It also provides its own timing mechanism to ensure that reliable time information is
available (e.g., for log accountability). The TOE can also be configured to work with an NTP server for reliable
time.
The TOE includes functions to perform self-tests so that it might detect when it is failing. It also includes
mechanisms (i.e., verification of the digital signature of each new image) so that the TOE itself can be updated while
ensuring that the updates will not introduce malicious or other unexpected changes in the TOE.
TOE access
The TOE can be configured to display a message of the day banner when an administrator establishes an interactive
session and subsequently will enforce an administrator-defined inactivity timeout value after which the inactive
session (local or remote) will be terminated.
Trusted path/channels
The TOE protects interactive communication with administrators using SSH for CLI access to ensure both integrity
and disclosure protection. If the negotiation of an encrypted session fails or if the user does not have authorization
for remote administration, an attempted connection will not be established.
The TOE protects communication with network peers, such as a log server, using TLS connections to prevent
unintended disclosure or modification of logs.
1.4.2 TOE Documentation
CommScope Technologies LLC offers a series of documents that describe the installation of the FastIron
switch/router products as well as guidance for subsequent use and administration of the applicable security features.
The following document was examined as part of the evaluation:

Table 1 Technical Decisions
2.1 Conformance Rationale
The ST conforms to the NDcPP22e. As explained previously, the security problem definition, security objectives,
and security requirements have been drawn from the PP.
FastIron ICX 9.0.10 Security Target Version 1.1, 06/23/2022
Page 9 of 32
3. Security Objectives
The Security Problem Definition may be found in the NDcPP22e and this section reproduces only the corresponding
Security Objectives for operational environment for reader convenience. The NDcPP22e offers additional information
about the identified security objectives, but that has not been reproduced here and the NDcPP22e should be consulted
if there is interest in that material.
In general, the NDcPP22e has defined Security Objectives appropriate for the Ruckus FastIron ICX Series
Switch/Router 9.0.10 TOE.
3.1 Security Objectives for the Operational Environment
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. Note: For vNDs the TOE includes only the contents of its own VM, and does not include other VMs or
the VS.
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 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. For vNDs, this applies
when the physical platform on which the VM runs is removed from its operational environment.
OE.TRUSTED_ADMIN TOE Administrators are trusted to follow and apply all guidance documentation in a trusted
manner. For vNDs, this includes the VS Administrator responsible for configuring the VMs that implement ND
functionality.
For TOEs supporting X.509v3 certificate-based authentication, the Security Administrator(s) are assumed to monitor
the revocation status of all certificates in the TOE’s trust store and to remove any certificate from the TOE’s trust store
in case such certificate can no longer be trusted.
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.

5. Security Requirements
This section defines the Security Functional Requirements (SFRs) and Security Assurance Requirements (SARs) that
serve to represent the security functional claims for the Target of Evaluation (TOE) and to scope the evaluation effort.
The SFRs have all been drawn from the NDcPP22e. The refinements and operations already performed in the
NDcPP22e are not identified (e.g., highlighted) here, rather the requirements have been copied from the NDcPP22e
and any residual operations have been completed herein. Of particular note, the NDcPP22e made a number of
refinements and completed some of the SFR operations defined in the Common Criteria (CC) and that PP should be
consulted to identify those changes if necessary.
The SARs are the set of SARs specified in NDcPP22e.

6. TOE Summary Specification
This chapter describes the security functions:
• Security audit
• Cryptographic support
• Identification and authentication
• Security management
• Protection of the TSF
• TOE access
• Trusted path/channels
6.1 Security audit
The TOE produces syslog conformant messages in a number of circumstances including warnings about the device
itself (such as temperature, power failures, etc.) as well as security relevant events (the success and failure login of
the user, regardless of the authentication mechanism; changing a user’s password; and adding and deleting user
accounts). In each case the audit record includes the time and date, identification of the responsible subject (e.g., by
network address or user ID), the type of event, the outcome of the event, and other information depending on the
event type. For cryptographic keys, the act of importing a key is audited and the associated administrator account is
identified using the trust point name corresponding to the operation being performed.
The audit records are stored in a log (internal to the TOE appliance) that is protected so that only an authorized TOE
User can read (for which tools accessible via the CLI are provided). The protection results from the fact that the
logs can be accessed only after a user logs in (see section 6.3 below).
The log stores up to 4,000 entries after which the audit entries will be overwritten, oldest first. The administrator
(with Super User privilege) can (and should) choose to configure one or more external syslog servers where the
TOE will simultaneously send a copy of the audit records. The TOE can be configured to use TLS (using any of the
supported ciphersuites) to protect audit logs exported to an external server.
The TOE includes a hardware clock that is used to provide reliable time information for the audit records it generates.
The Security audit function satisfies the following security functional requirements:
• NDcPP22e:FAU_GEN.1: The TOE can generate audit records for events including starting and stopping
the audit function, administrator commands, and all other events identified in Table 3 (in Section 5).
Furthermore, each audit record identifies the date/time, event type, outcome of the event, responsible
subject/user, as well as the additional event-specific content indicated in Table 3 (in Section 5).
• NDcPP22e:FAU_GEN.2: The TOE identifies the responsible user for each event based on the specific
administrator or network entity (identified by IP address) that caused the event.
• NDcPP22e:FAU_STG_EXT.1: The TOE can be configured to export audit records to an external SYSLOG
server. This communication is protected with the use of TLS.
6.2 Cryptographic support
The TOE supports a range of cryptographic services using the as the RUCKUS-IP-CRYPTO-VER-5.0. The
following functions have been CAVP tested.

Table 5 Cryptographic Functions
The TOE uses a software-based random bit generator that complies with Special Publication 800-90 using
CTR_DRBG when operating in the FIPS mode. AES-256 is used in conjunction with a minimum of 256 bits of
entropy.
The TOE supports the following secret keys, private keys and CSPs:

Table 6 Keys and CSPs
The TOE stores all persistent secret and private keys in FLASH and stores all ephemeral keys in RAM (as indicated
in the above table). The TOE’s zeroization has been subjected to FIPS 140 validation. Note that zeroization occurs as
follows: 1) when deleted from FLASH, the previous value is overwritten once with zeroes; 2) when added or changed
in FLASH, any old value is overwritten completely with the new value; and, 3) the zeroization of values in RAM is
achieved by overwriting once with zeroes.
These supporting cryptographic functions are included to support the SSHv2 (compliant with RFCs 4251, 4252,
4253, and 4254) and TLS v1.1 (RFC4346), and TLS v1.2 (RFC 5246) secure communication protocols.
The TOE supports TLSv1.1, and v1.2 with the following ciphersuites:
• TLS_DHE_RSA_WITH_AES_128_CBC_SHA
• TLS_DHE_RSA_WITH_AES_256_CBC_SHA
• TLS_DHE_RSA_WITH_AES_128_CBC_ SHA256
• TLS_DHE_RSA_WITH_AES_128_GCM_SHA256
The TOE supports the Supported Elliptic Curves/Supported Groups Extension with ffdhe2048 by default.
The TOE supports SSHv2 with AES (CTR, CBC) 128 or 256 bit ciphers, in conjunction with HMAC-SHA-1 or
HMAC-SHA2-256. The TOE supports ssh-rsa, rsa-sha2-256, rsa-sha2-512, and ecdsa-sha2-nistp384 as its host public
key algorithms, with diffie-hellman-group14-sha256, diffie-hellman-group16-sha512, diffie-hellman-group18-
sha512, ecdh-sha2-nistp256 and ecdh-sha2-nistp384 for the key exchange methods. While other ciphers and hashes
are implemented in the product, they are disabled while the TOE is operating in Common Criteria mode.
The TOE allows users to perform SSHv2 authentication using password based authentication and allows users to
upload a public key for SSHv2 public key client authentication. The imported SSHv2 public key includes a username
provided in the "Subject" field to be verified against an authenticating admin’s identity. The TOE’s SSHv2
implementation limits SSH packets to a size of 256K bytes. Whenever the timeout period or authentication retry limit
is reached, the TOE closes the applicable TCP connection and releases the SSH session resources. As SSH packets
are being received, the TOE uses a buffer to build all packet information. Once complete, the packet is checked to
ensure it can be appropriately decrypted. However, if it is not complete when the buffer becomes full (256K bytes)
the packet will be dropped and the connection terminated. There is a TOE initiated rekey before 1 hour or before 1GB
whichever comes first.

DH 14 SSH Remote Administration (server)
FFC TLS Syslog and Radius (client)
The Cryptographic support function satisfies the following security functional requirements:
• NDcPP22e:FCS_CKM.1: The TOE supports asymmetric key generation using RSA key establishment (key
size 2048) as part of SSH as described in the section above. The TOE acts as a client for TLS (FFC) and a
server for SSH (RSA, ECC, DH-14 key generation). The TOE supports DH group 14 key establishment
scheme that meets standard RFC 3526, section 3 for interoperability. The TOE implements NIST Special
Publication 800-56A Revision 2, 'Recommendation for Pair-Wise Key Establishment Schemes Using
Discrete Logarithm Cryptography'.
• NDcPP22e:FCS_CKM.2: See NDcPP22e:FCS_CKM.1.
• NDcPP22e:FCS_CKM.4: Keys are zeroized when they are no longer needed by the TOE
• NDcPP22e:FCS_COP.1/DataEncryption: The TOE performs encryption and decryption using AES in CBC
and CTR mode with key sizes of either 128 or 256. The corresponding CAVP certificate is identified in the
table above.
• NDcPP22e:FCS_COP.1/Hash: The TOE supports cryptographic hashing services using SHA-1 and SHA-
256 with digest sizes 160 and 256. The corresponding CAVP certificate is identified in the table above,
• NDcPP22e:FCS_COP.1/KeyedHash: The TOE supports keyed-hash message authentication using HMAC-
SHA-1 and HMAC-SHA-256, using SHA-1/256 with 160/256 bit keys to produce a 160/256 output MAC.
The corresponding CAVP certificate is identified in the table above
• NDcPP22e:FCS_COP.1/SigGen: The TOE supports the use of RSA with 2048 bit key sizes for
cryptographic signatures. Digital signatures are used in TLS and SSH communications and on product
updates. The corresponding CAVP certificate is identified in the table above.
• NDcPP22e:FCS_NTP_EXT.1: The TOE supports NTPv3 and NTPv4, authenticating the NTP server that it
synchronizes to using a sha1 message digest. The TOE allows one or more NTP servers to be configured.
At least one is required for time synchronization to occur, but more than 3 NTP servers can be specified.
• NDcPP22e:FCS_RBG_EXT.1: The TOE uses one software-based entropy source to seed for a software-
based DRBG that complies with Special Publication 800-90 using CTR_DRBG when operating in the FIPS
mode. AES-256 is used in conjunction with a minimum of 256 bits of entropy for the seed.
• NDcPP22e:FCS_SSHS_EXT.1: The TOE supports SSHv2 interactive command-line secure administrator
sessions as indicated above.
• NDcPP22e:FCS_TLSC_EXT.1: The TOE supports TLS when exporting audit logs to an external server
and when communicating with RADIUS authentication servers. Certificate pining is not supported. The
TOE supports FQDN reference identifiers from RFC 6125 only.
6.3 Identification and authentication
The TOE requires users to be identified and authenticated before they can use functions mediated by the TOE,
except to display a message of the day banner and to permit network routing services without identification or
authentication. The TOE allows unauthenticated network routing services to route network traffic through the TOE
as well as unauthenticated network routing protocol traffic destined to the TOE (including DNS, ARP, ICMP,
BootP, DHCP, RIP, OSPF, BGP, VRRP, VRRP-E, Multi-VRF) but does not include any management configuration
of the TOE’s network routing services. The TOE authenticates TOE Users against their user name, password and
privilege level. The Authorized Administrator logs on the TOE through either locally using the console or remotely
using SSHv2. A successful authentication is determined by a successful username and password combination. An
incorrect password will result in a failed authentication attempt. The TOE also allows remote administrators to
authenticate over an SSH connection using an RSA public key authentication mechanism.
The Authorized Administrator with Super User privilege represents the “administrator” referred to in the security
requirements of the protection profile. Other accounts with privileges other than Super User were not tested during
the evaluation. The available mechanisms include the Local Password for the Super User Privilege level and
RADIUS authentication. The Authorized Administrator with Super User privilege defines local user (or TOE User)
FastIron ICX 9.0.10 Security Target Version 1.1, 06/23/2022
Page 29 of 32
accounts and assigns passwords and privilege levels to the accounts. Each user account has a user name, password,
and a privilege level associated with it. There is a default privilege level account associated with each privilege level
and each has its own password. It is up to the Authorized Administrator with Super User privilege to decide whether
or how to use these legacy accounts. Note however, that each has an identity, password, and privilege level.
While the Authorized Administrator with Super User privilege can create or otherwise modify accounts freely, other
users cannot change their own (or any other) security attributes. Note that the TOE supports a password
enforcement configuration where the minimum password length can be set by an administrator from 8 to 60
characters. Passwords can be created using any alphabetic, numeric, and a wide range of special characters (
~!@#$%^&*()_+{}[]:;"'<>,./|\ ).
The Authorized Administrator can set a lockout failure count for remote login attempts (the default is 3). If the count
is exceeded, the targeted account is locked for an administrator-configurable time limit. Once the configured time has
passed the account is unlocked. No manual administrative action is required. The local console interface is not subject
to the lockout failure enforcement.
The Identification and authentication function satisfies the following security functional requirements:
• NDcPP22e:FIA_AFL.1: Remote administrator accounts can be locked for an administrator configured
period of time if the failed login threshold is surpassed. Once the configured time has passed the account is
unlocked. No manual administrative action is required.
• NDcPP22e:FIA_PMG_EXT.1: The TOE implements a rich set of password composition constraints as
described above.
• NDcPP22e:FIA_UAU.7: The TOE does not echo passwords as they are entered; rather ‘*’ characters are
echoed when entering passwords.
• NDcPP22e:FIA_UAU_EXT.2: The TOE uses local password-based authentication and RADIUS server
authentication.
• NDcPP22e:FIA_UIA_EXT.1: The TOE does not offer any services or access to its functions, except for the
switching/routing of network traffic and displaying a message of the day banner, without requiring a user to
be identified and authenticated.
• NDcPP22e:FIA_X509_EXT.1/Rev: Certificates are validated as part of the authentication process when
they are presented to the TOE and when they are loaded into the TOE. OCSP is supported for X509v3
certificate validation of certificates used for authentication by a TLS server. Trusted CA’s are loaded to the
file system in PEM format using a CLI command leveraging SCP. As this requires CLI access this can only
be performed by authorized administrators who have been authenticated. The TOE chooses what trusted
CA to use for certificate chain validation based on the trustpoint configured for the relevant TLS profile.
• NDcPP22e:FIA_X509_EXT.2: Certificates are checked and if found not valid are not accepted or if the
OCSP server cannot be contacted for validity checks, then the certificate is not accepted. This behavior is
not configurable. Certificates are checked in the following order: chain validation, SAN checks, CN
checks, revocation status, and lastly expiration status. The common name (or SAN values if present) needs
to be a fully qualified domain name. Wildcards are not allowed in certificates.
6.4 Security management
The TOE associates each defined user account with a privilege level. The most privileged level is Super User (with
regards to the requirements in this Security Target, users with lesser privilege levels are referred to collectively
simply as TOE users since such users do not have complete read-and-write access to the system). Again, as stated in
section 6.3, other accounts with privileges other than Super User were not tested during the evaluation. The TOE
implements an internal access control mechanism that bases decisions about the use of functions and access to TOE
data on those privilege levels. In this manner, the TOE is able to ensure that only the Authorized Administrator with
Super User privilege can access audit configuration data, information flow policy ACLs, user and administrator
security attributes (including passwords and privilege levels), authentication method lists, the logon failure
threshold, the remote access user list; and cryptographic support settings.
Other than the Super User level, the TOE implements a Read Only level where only basic commands can be issued
and no changes can be made and a Port Configuration level where non-security device parameters can be managed.
FastIron ICX 9.0.10 Security Target Version 1.1, 06/23/2022
Page 30 of 32
Collectively, this ST refers to all users of the TOE as “TOE Users” where TOE Users privileges are a subset of the
broader role of “Authorized Administrator with Super User privilege”.
The TOE offers command line functions which are accessible via the CLI. The CLI is a text based interface which
can be accessed from a directly connected terminal or via a remote terminal using SSH. These command line functions
can be used to effectively manage every security policy, as well as the non-security relevant aspects of the TOE.
Once authenticated (none of these functions is available to any user before being identified and authenticated),
authorized administrators have access to the following security functions:
• Ability to administer the TOE locally and remotely;
• Ability to configure the access banner;
• Ability to configure the session inactivity time before session termination or locking;
• Ability to update the TOE, and to verify the updates using digital signature capability
prior to installing those updates;
• Ability to configure the authentication failure parameters for FIA_AFL.1;
• Ability to modify the behavior of the transmission of audit data to an external IT
entity;
• Ability to manage the cryptographic keys
• Ability to configure the cryptographic functionality;
• Ability to configure thresholds for SSH rekeying;
• Ability to set the time which is used for time-stamps;
• Ability to configure NTP;
• Ability to configure the reference identifier for the peer;
• Ability to manage the TOE's trust store and designate X509.v3 certificates as trust
anchors;
• Ability to import X509v3 certificates to the TOE's trust store;
• Ability to manage the trusted public keys database;
The Security management function satisfies the following security functional requirements:
• NDcPP22e:FMT_MOF.1/ManualUpdate: Only the authorized administrator can update the TOE.
• NDcPP22e:FMT_MTD.1/CoreData: Only the authorized administrator can configure TSF-related
functions.
• NDcPP22e:FMT_MTD.1/CryptoKeys: Only the authorized administrator can configure cryptographic
keys. The keys an authorized administrator can manage consist of importing trusted Root CA certs,
generating SSH host keys, and importing SSH public keys. All of these keys can be also be deleted.
• NDcPP22e:FMT_SMF.1: The TOE provides administrative interfaces to perform the functions identified
above.
• NDcPP22e:FMT_SMR.2: The TOE maintains administrative user roles.
6.5 Protection of the TSF
The TOE is an appliance and as such is designed to work independent of other components to a large extent. Secure
communication with third-party peers as addressed in section 6.7.
The TOE does not provide access to locally stored passwords (which can be administratively configured to be
protected by SHA-1 or SHA-256) and also, while cryptographic keys can be entered, the TOE does not disclose any
cryptographic keys stored in the TOE. The TOE is a hardware appliance that includes a hardware-based real-time
clock. The TOE’s embedded OS manages the clock and exposes administrator clock-related functions. The TOE can
be configured to periodically synchronize its clock with a time server, but the TOE can only ensure its own
reliability and not that of an external time mechanism. The TOE also implements the timing elements through
timeout functionality due to inactivity for terminating both local and remote sessions. Note that the clock is used
primarily to provide timestamp for audit records, but is also used to support timing elements of cryptographic
functions.
FastIron ICX 9.0.10 Security Target Version 1.1, 06/23/2022
Page 31 of 32
The TOE includes a number of built in diagnostic tests that are run during start-up to determine whether the TOE is
operating properly. If a self-test fails, the TOE is not operational and reboots until the error is cleared or the
administrator gets help from Ruckus. When operating in FIPS mode, the power-on self-tests comply with the FIPS
140-2 requirements for self-testing. The module performs Cryptographic algorithm known answer tests, firmware
integrity tests using RSA signature verification and conditional self-tests for DRBG, Hardware RNG, Pair-wise
consistency tests on generation of RSA keys, and a Firmware load test (RSA signature verification). Upon failing
any of its FIPS mode power-on self-tests, the TOE will refuse to boot. The tests are sufficient to ensure the correct
operation of the security features as they address firmware integrity and cryptographic operations.
The TOE supports loading a new software image manually by the administrator using CLI commands. From the CLI,
an administrator can use SCP in order to download a software image, and the TOE, prior to actually installing and
using the new software image, will verify its digital signature using a pre-installed vendor key. An unverified image
cannot be installed. The downloaded software image is saved to flash memory and is installed after rebooting the
TOE.
The Protection of the TSF function satisfies the following security functional requirements:
• NDcPP22e:FPT_APW_EXT.1: The TOE does not offer any functions that will disclose to any user a plain
text password. Furthermore, locally defined passwords are not stored in plaintext form..
• NDcPP22e:FPT_SKP_EXT.1: The TOE does not offer any functions that will disclose to any users a stored
cryptographic key. Keys are stored as identified in Table 6 when they are created
• NDcPP22e:FPT_STM_EXT.1: The TOE includes its own hardware clock and can synchronize its time
with an external NTP server.
• NDcPP22e:FPT_TST_EXT.1: The TOE performs a suite of self-tests to verify its integrity.
• NDcPP22e:FPT_TUD_EXT.1: The TOE provides functions to query the version and upgrade the software
embedded in the TOE appliance. When installing updated software, digital signatures are used to
authenticate the update to ensure it is the update intended and originated by the vendor.
6.6 TOE access
The TOE can be configured to display an administrator-configured message of the day banner that will be displayed
before authentication is completed (before the user enters his password). The banner will be displayed when accessing
the TOE via the console or SSH interfaces.
The TOE can be configured by an administrator to set a session timeout value (any value 0-240 minutes for console
and SSH with 0 disabling the timeout). The default timeout is 2 minutes for both console and SSH. A session (local
or remote) that is inactive (i.e., no commands issuing from the remote client) for the defined timeout value will be
terminated. Upon exceeding the session timeout (if set), the TOE logs the user off, but leaves the user’s console
displaying the last contents.
The user will be required to login in after any session has been terminated due to inactivity or after voluntary
termination. Of course, administrators can logout of local or remote sessions at any time.
The TOE access function satisfies the following security functional requirements:
• NDcPP22e:FTA_SSL.3: The TOE terminates remote sessions that have been inactive for an administrator-
configured period of time.
• NDcPP22e:FTA_SSL.4: The TOE provides the function to logout (or terminate) both local and remote user
sessions as directed by the user.
• NDcPP22e:FTA_SSL_EXT.1: The TOE terminates local sessions that have been inactive for an
administrator-configured period of time.
• NDcPP22e:FTA_TAB.1: The TOE can be configured to display administrator-defined advisory banners
when administrators successfully establish interactive sessions with the TOE, allowing administrators to
terminate their session prior to performing any functions.
FastIron ICX 9.0.10 Security Target Version 1.1, 06/23/2022
Page 32 of 32
6.7 Trusted path/channels
The TOE provides a trusted path for its remote administrative users accessing the TOE via the Ethernet ports
provided on the TOE using either the command line interface or SSH. Note that local administrator access via the
serial port is also allowed for command line access. However this access is protected by physical protection of the
serial interface along with the TOE itself.
When an administrator attempts to connect to the TOE remotely, the TOE attempts to negotiate a session. If the
session cannot be negotiated, the connection is dropped.
Remote connections to third-party SYSLOG servers are supported for exporting audit records to an external audit
server and for external user authentication using a RADIUS server. Communication with those external servers is
protected using TLS (as specified earlier).
In all cases, the endpoints are assured by virtue of the certificates installed, trusted, and reviewable when connecting
and by virtue of user authentication.
The Trusted path/channels function satisfies the following security functional requirements:
• NDcPP22e:FTP_ITC.1: In the evaluated configuration, the TOE can be configured to use TLS to ensure
that any exported audit records and authentication server communications are sent only to the configured
server so they are not subject to inappropriate disclosure or modification
• NDcPP22e:FTP_TRP.1/Admin: The TOE uses SSH to provide a trusted path for remote management
interfaces to protect the communication from disclosure and modification.
