Columbia, MD CCEVS Validators Sheldon Durrant, Randy Heimann, Linda Morrison, Clare Parran (The MITRE Corporation) Infinera mTera Universal Transport Platform Validation Report Version 0.3, August 31, 2021 3 3 Architectural Information Note: The following architectural description is based on the description presented in the Security Target. The Infinera mTera Universal Transport Platform is an extremely flexible and highly efficient transport solution supporting up to 12Tb/s of switching and grooming for OTN, Packet and SONET/SDH leveraging protocol agnostic fabrics and interface cards that can be software configured for OTN, MPLS-TP or Carrier Ethernet on each interface or virtual interface. The Infinera mTera is offered in either a 16-slot chassis or 8-slot chassis. The mTera is an optical network appliance delivering Wavelength, High-capacity Electrical OTN, and Packet network switching. The mTera supports electrical switching using an agnostic switch fabric. Signals switched by the electrical switch fabric include high-capacity ITU Optical Transport Network (OTN) ODU switching, ITU/ANSI SDH/SONET switching and service oriented MPLS-TP/Ethernet packet switching. The security functions provided include Identification, Authentication, Access Control, Protection of TSF, Confidentiality, Integrity and Auditing. 3.1 TOE Evaluated Configuration Detail regarding the evaluated configuration is provided in Section 8 below. 3.2 TOE Architecture The Infinera mTera is a network appliance composed of various module slots. The mTera supports up to two STPM (shelf timing and processor module) cards for management in addition to optical network switch blades. The mTera TOE's management capabilities rely on TL1 commands. The mTera’s interfaces provide TLS and IPsec functionality as well as SSHv2 for management. The mTera STPM includes an LCI (local craft interface) port for local CLI access and DCN (data communications network) ports for network communications. Though an administrator uses SSH to connect to the mTera through both interfaces, the LCI port does not provide network routing, thus requiring an administrator to connect directly to the LCI port for local console access. The mTera TOE contains an OpenSSL FIPS object module and a kernel crypto module for cryptographic services. The Kernel Crypto module is used for IPSEC data path (encrypt/decrypt, message authentication, hash) while the OpenSSL module is used for IPSEC Key management (i.e. IKE), SSH and TLS operations. The OpenSSL module is used for secret negotiation, authentication, encrypt/decrypt, message authentication, hashes and DRBG. 3.3 Physical Boundaries The TOE's physical boundary includes the entire chassis, which contains the STPM management and optical network line cards. The TOE runs firmware version FP.5.1.2p1. Infinera mTera Universal Transport Platform Validation Report Version 0.3, August 31, 2021 4 The TOE operates with the following components in the Operating Environment: • Audit Server – The TOE utilizes an external syslog server to store audit records. • Authentication Server – The TOE has the ability to use RADIUS servers to authenticate users. • Time Server – The TOE uses a Network Time Protocol (NTP) server to synchronize its system clock with a central time source. • SSH Client – The remote administrator uses an SSH client to access the CLI. 4 Security Policy This section summaries the security functionality of the TOE: 1. Security audit 2. Cryptographic support 3. Identification and authentication 4. Security management 5. Protection of the TSF 6. TOE access 7. Trusted path/channels 4.1 Security audit The TOE is designed to be able to generate logs for a wide range of security relevant events including start-up and shutdown of the TOE, all administrator actions, and all events identified in the Security Target, Table 2 Auditable Events. The TOE can be configured to store the logs locally so they can be accessed by an administrator or alternately to send the logs to a designated syslog server in the operational environment. 4.2 Cryptographic support The TOE includes cryptographic modules that provide key management, random bit generation, encryption/decryption, digital signature and secure hashing and key-hashing features in support of higher level cryptographic protocols including IPsec, SSH, and TLS. 4.3 Identification and authentication The TOE requires administrators to be identified and authenticated before they can access any TOE security functions. The TOE supports role-based authentication, so user accounts are assigned predefined roles which restrict them based on their assigned role. The TOE maintains these administrator and user attributes which can be defined locally with user names and passwords or can be defined in the context of local RADIUS services. Authentication can be either locally or remotely through an external authentication server, or internally. After an administrator-specified number of failed attempts, the user account is locked out. The TOE’s password mechanism provides configuration for a minimum Infinera mTera Universal Transport Platform Validation Report Version 0.3, August 31, 2021 5 password length. The TOE also protects, stores and allows authorized administrators to load X.509.v3 certificates for use to support authentication for IPsec, TLS and SSH connections. 4.4 Security management The TOE provides the administrator role the capability to configure and manage all TOE security functions including cryptographic operations, user accounts, passwords, advisory banner, session inactivity and TOE updates. The management functions are restricted to the administrator role. The role must have the appropriate access privileges or access will be denied. The TOE’s cryptographic functions ensure that only secure values are accepted for security attributes. 4.5 Protection of the TSF The TOE has its own internal hardware clock that provides reliable time stamps used for auditing. The TOE stores passwords on flash and encrypts the passwords using an AES-256- CBC key. The TOE does not provide any interfaces that allow passwords or keys to be read. The TOE also provides integrity and security protection for all communication between its components. This prevents unauthorized modification or disclosure of TSF data during transmission. The TOE runs self-tests during power up and periodically during operation to ensure the correct operation of the cryptographic functions and TSF hardware. There is an option for the administrator to verify the integrity of stored TSF executable code. The TOE executes self-tests for both the Kernel Crypto module and OpenSSL FIPS Object module. The TOE includes mechanisms so that the administrator can determine the TOE version and update the TOE securely using digital signatures. 4.6 TOE access The TOE allows administrators to configure a period of inactivity for administrator and user sessions. Once that time period has been reached while the session has no activity, the session is terminated. All users may also terminate their own sessions at any time. A warning banner is displayed at the management interfaces (local CLI and SSH) to advise users on appropriate use and penalty for misuse of system. 4.7 Trusted path/channels The TOE uses IPsec to provide an encrypted channel between itself and third-party trusted IT entities in the operating environment including external syslog server, external authentication server and NTP server. The TOE also uses IPsec to encrypt communications between the TOE and external IT entities. The TOE uses TLS to secure network communications with an external optical network peer. The TOE secures remote communication with administrators by implementing SSHv2 for CLI access. Both the integrity and disclosure protection are ensured via the secure protocol. Infinera mTera Universal Transport Platform Validation Report Version 0.3, August 31, 2021 6 If the negotiation of a secure session fails or if the user cannot be authenticated for remote administration, the attempted session will not be established. 5 Assumptions & Clarification of Scope Assumptions The Security Problem Definition, including the assumptions, may be found in the following documents: • collaborative Protection Profile for Network Devices, version 2.1, 24 September 2018 That information has not been reproduced here and the NDcPP21 should be consulted if there is interest in that material. The scope of this evaluation was limited to the functionality and assurances covered in the NDcPP21 as described for this TOE in the Security Target. Other functionality included in the product was not assessed as part of this evaluation. All other functionality provided by the devices needs to be assessed separately, and no further conclusions can be drawn about their effectiveness. Clarification of scope All evaluations (and all products) have limitations, as well as potential misconceptions that need clarification. This text covers some of the more important limitations and clarifications of this evaluation. Note that: • As with any evaluation, this evaluation only shows that the evaluated configuration meets the security claims made with a certain level of assurance (the assurance activities specified in the collaborative Protection Profile for Network Devices and performed by the evaluation team). • This evaluation covers only the specific device models and software as identified in this document, and not any earlier or later versions released or in process. • This evaluation did not specifically search for, nor attempt to exploit, vulnerabilities that were not “obvious” or vulnerabilities to objectives not claimed in the ST. The CEM defines an “obvious” vulnerability as one that is easily exploited with a minimum of understanding of the TOE, technical sophistication and resources. • The functionality evaluated is scoped exclusively to the security functional requirements specified in the NDcPP21 and applicable Technical Decisions. Any additional security related functional capabilities of the TOE were not covered by this evaluation. 6 Documentation The following documents were available with the TOE for evaluation: • mTera Universal Transport Platform version MT5.1.2 Security Target, v0.5, August 26, 2021 Infinera mTera Universal Transport Platform Validation Report Version 0.3, August 31, 2021 7 • Coriant Product Hardening Guide, Version BP11, August 23, 2021 • TL1 Specification, version CP11, August 26, 2021 7 IT Product Testing This section describes the testing efforts of the developer and the Evaluation Team.

Infinera mTera Universal Transport Platform Validation Report Version 0.3, August 31, 2021 10 9.1 Summary of Evaluation Results The evaluation team’s assessment of the evaluation evidence demonstrates that the claims in the ST are met. Additionally, the evaluation team’s testing also demonstrated the accuracy of the claims in the ST. The validation team’s assessment of the evidence provided by the evaluation team is that it demonstrates that the evaluation team followed the procedures defined in the CEM, and correctly verified that the product meets the claims in the ST. 10 Validator Comments/Recommendations The validation team notes that the evaluated configuration is dependent upon the TOE being configured per the evaluated configuration instructions in the document “Coriant Product Hardening Guide, Version BP11”, dated 23 August 2021. No versions of the TOE and software, either earlier or later were evaluated. Please note that the functionality evaluated is scoped exclusively to the security functional requirements specified in the Security Target. Other functionality included in the product was not assessed as part of this evaluation. Other functionality provided by devices in the operational environment, such as a management workstation, need to be assessed separately and no further conclusions can be drawn about their effectiveness. The evaluation and testing of security functional requirements are scoped by the guidance included by the Assurance Activity associated with the Protection Profile claimed by the TOE. There is an inherent risk that elements of the TOE security functionality were not fully evaluated. It is recommended that the TOE be subject to integration testing within its intended environment to ensure proper configuration, compliance, and operation. 11 Annexes Not applicable 12 Security Target The Security Target is identified as: mTera Universal Transport Platform version MT5.1.2 (NDcPP21) Security Target, Version 0.5, August 26, 2021. 13 Glossary The following definitions are used throughout this document: • Common Criteria Testing Laboratory (CCTL).
