The Target of Evaluation (TOE) is Extreme Networks, Inc. NetIron Family Devices with Multi-Service IronWare R06.3.0aa. The TOE is a network appliance providing routing and virtual private network functions.
The TOE is composed of a hardware appliance with embedded software installed on a management processor. The embedded software is a version of Extreme’s proprietary Multi-Service IronWare software. The software controls the switching and routing of network frames and packets among the connections available on the hardware appliances. The TOE includes a card (BR-MLX-10GX4-IPSEC-M) that supports IPsec processing on the 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 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 IPsec. All of the remote management interfaces are protected using encryption as explained in the ST.
The hardware platforms that support the TOE have a number of common hardware characteristics:
The evaluated TOE is an appliance installed with NetIron firmware Version 06.3.00aa. The TOE must be configured in accordance with the Extreme NetIron Configuration Guide for CC, VPN Gateway Profile, 06.3.00aa, April 2020. The TOE includes the following hardware and models:
Security Evaluation Summary
The evaluation was carried out in accordance to the Common Criteria Evaluation and Validation Scheme (CCEVS) requirements and guidance. The evaluation demonstrated that the TOE meets the security requirements contained in the Security Target. The criteria against which the TOE was judged are described in the Common Criteria for Information Technology Security Evaluation, Version 3.1, Revision 5, April 2017. The evaluation methodology used by the evaluation team to conduct the evaluation is the Common Methodology for Information Technology Security Evaluation, Evaluation Methodology, Version 3.1, Revision 5, April 2017.
Gossamer Security Solutions determined that the evaluation assurance level (EAL) for the TOE is EAL 1. The product, when delivered and configured as identified in the Extreme NetIron Configuration Guide for CC, VPN Gateway Profile, 06.3.00aa, April 2020 document, satisfies all of the security functional requirements stated in the Extreme Networks, Inc. NetIron Family Devices with Multi-Service IronWare R06.3.0aa (NDcPP21/VPNGW10) Security Target, Version 0.4, May 27, 2020.
The project underwent CCEVS Validator review. The evaluation was completed in June 2020. Results of the evaluation can be found in the Common Criteria Evaluation and Validation Scheme Validation Report (report number CCEVS-VR-VID11073-2020) prepared by CCEVS.
The logical boundaries of the Extreme Networks NetIron Family Devices with Multi-Service IronWare R06.3.0aa appliances are realized in the security functions that it implements. Each of these security functions is summarized below.
Security Audit: The TOE is designed to be 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 IPsec to protect the logs while in transit on the network.
Cryptographic Support: The TOE contains a cryptographic module with algorithms that have been Cryptographic Algorithm Validation Program (CAVP)-certified 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.
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.
Packet Filtering: The TOE provides extensive packet filtering capabilities for IPv4, IPv6, TCP, and UDP. The authorized administrator can define packet filtering rules that apply to most every field within the identified packet types. The authorized administrator can define each rule to permit, deny, and log each decision.
Protection of the TSF: The TOE implements features to protect itself to ensure the reliability and integrity of its security functionality.
It protects 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).
Note that the TOE is a single appliance, and as such, no intra-TOE communication is subject to any risks that may require special protection (e.g., cryptographic mechanisms).
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 IPsec for CLI access. In each case, the both integrity and disclosure protection is ensured. If the negotiation of an encrypted session fails or if the user does not have authorization for remote administration, the attempted connection will not be established.
The TOE protects communication with network peers, such as a log server, using IPsec connections to prevent unintended disclosure or modification of logs.
