Extreme Networks, Inc. VDX Product Series with NOS Validation Report Version 1.0.0, January 11, 2019 3 The TOE is VDX Product Series operating with NOS version 7.3.0aa. The VDX Product Series operating with NOS version 7.3.0aa are hardware appliances with embedded software installed on a management processor. VDX switches, featuring embedded automation capabilities of Extreme data center fabrics, deliver high performance, capacity, and reliability in data center spine and leaf deployments. Optionally, a number of co-located appliances can be connected in order to work as a unit with a common security policy. The embedded software is a version of Extreme Network’s proprietary Multiservice NOS. The NOS controls the switching and routing of network frames and packets among the connections available on the hardware appliances. These switch/routers include virtual cluster switch (VCS), which allows users to create flatter, virtualized and converged data center networks. These VCS fabrics are scalable, permitting users to expand at their own pace, and simplified, allowing users to manage the fabric as a single entity. VCS-based Ethernet fabrics are convergence-capable. All TOE appliances are configured at the factory with default parameters and an admin and user account with default passwords. Users must login to access 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 SSH. Administrator can also use REST APIs (over HTTPS) or NetConf (over SSH) for configuring the TOE. The TOE uses SCP to download/compare software images. The TOE includes the following models with accompanying CPUs: Model CPU VDX- 6740, 6740-T, 6740T-1G, VDX-6940-36Q Freescale P3041 four e500mc core processors at 1.5 Ghz VDX6940-144S, VDX8770-4 and VDX8770-8 (including 8770-MM-1) Freescale P4080 four e500mc core processors at 1.5 Ghz The VDX 6740 switch is a fixed port switch with 48 10-Gigabit Ethernet (GbE) SFP+ interfaces and four 40 GbE independent 10 GbE SFP+ ports, providing an additional 16 10 GbE SFP+ ports. The Extreme Networks VDX 6740T offers 48 10 GbE 10BASE-T ports and four 40 GbE QSFP+ ports. Each can be broken out into four independent 10 GbE SFP+ ports, providing an additional 16 10 GbE SFP+ ports. The Extreme Networks VDX 6740T- 1G offers 48 1000BASE-T ports and two 40 GbE QSFP+ ports. Each 40 GbE port can be broken out into four independent 10 GbE SFP+ ports, providing an additional eight 10 GbE SFP+ ports for uplink. The VDX 6940-36Q base system has thirty-six 40 Gigabit Ethernet (GbE) QSFP+ ports enabled, or 36 ports can be configured as 144 10Gbe QSFP+ ports in breakout mode. Extreme Networks, Inc.

The 8770 hardware platforms that support the TOE have a number of common hardware characteristics:  Dual, redundant management modules  Serial (console), Ethernet, and USB connections for management modules (though only Brocade branded USB devices are supported)  Support for short-range and long-range 1 Gbps SFP transceivers  Support for short-range and long range 10 Gbps SFP+ transceivers  Support for 40 Gbps QSFP transceivers 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 or dropped in accordance with a configured policy. 3.1 TOE Evaluated Platforms The evaluated configuration consists of the following models:  VDX 6740  VDX 6740-T  VDX 6740T-1G  VDX 6940-36Q  VDX 6940-144S  VDX 8770-4 w/ 8770-MM-1 management module  VDX 8770-8 w/ 8770-MM-1 management module Extreme Networks, Inc. VDX Product Series with NOS Validation Report Version 1.0.0, January 11, 2019 5 3.2 TOE Architecture The basic architecture of each TOE appliance begins with a hardware appliance with physical network connections. Within the hardware appliance the Extreme Networks NOS is designed to control and enable access to the available hardware functions (e.g., program execution, device access, facilitate basic routing and switching functions). NOS enforces applicable security policies on network information flowing through the hardware appliance. Given that the ST conforms to the NDCPP20E, the security claims focus on the TOE as a secure network infrastructure device and do not focus on other key functions provided by the TOE, such as controlling the flow of network packets among the attached networks. The TOE protects itself from tampering and bypass by offering only a limited and controlled set of functions at each of its physical interfaces to its environment. Communication via those interfaces is either directed at the TOE for the purpose of administration or is directed through the TOE for communication among network devices. In both cases, the TOE implements a set of policies to control the services available and those services are designed to protect and ensure the secure operation of the TOE. 3.3 Physical Boundaries Each TOE appliance runs a version of the Extreme Networks NOS and 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 the environment which can be remote from or directly connected to the TOE. The TOE can be configured to forward its audit records to a syslog server in the environment. This is generally advisable given the limited audit log storage space on the evaluated appliances. The TOE sets its internal clock using administrative command issued at the CLI interface. 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 Extreme Networks, Inc. VDX Product Series with NOS Validation Report Version 1.0.0, January 11, 2019 6 4.1 Security audit The TOE generates audit events for numerous activities including policy enforcement, system management and authentication. A syslog server in the environment is relied on to store audit records generated by the TOE. The TOE generates a complete audit record including the IP address of the TOE, the event details, and the time the event occurred. The time stamp is provided by the TOE appliance hardware. 4.2 Cryptographic support The TOE contains CAVP-tested cryptographic implementations 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 SSH and TLS. 4.3 Identification and authentication The TOE authenticates administrative users. In order for an administrative user to access the TOE, a user account including a user name and password must be created for the user, and an administrative role must be assigned. The TOE performs the validation of the login credentials 4.4 Security management The TOE provides CLI commands to access the wide range of security management functions to manage its security policies. The TOE also provides REST APIs (protected by TLS) and NetConf (protected by SSH) to configure the TOE. Security management commands are limited to authorized users (i.e., administrators) and available 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 Authorized Administrator role can actually manage the security policies provided by the TOE and the TOE offers a complete set of functions to facilitate effective management. 4.5 Protection of the TSF The TOE implements a number of features design 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). Note that the TOE is a single appliance or a closely grouped (e.g., in the same rack) collection of appliances acting as a unit. As such, no intra-TOE communication is subject to any risks that may require special protection (e.g., cryptographic mechanisms). Extreme Networks, Inc. VDX Product Series with NOS Validation Report Version 1.0.0, January 11, 2019 7 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. 4.6 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. 4.7 Trusted path/channels The TOE protects interactive communication with administrators using SSHv2 for CLI and NetConf access, ensuring 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 also provides a REST API interface for security management that is protected with TLS. The TOE protects communication with network peers, such as a log server, using TLS connections to prevent unintended disclosure or modification of logs. SSHv2 is used to support SCP which the TOE uses for download of TOE updates. 5 Assumptions The Security Problem Definition, including the assumptions, may be found in the following document:  collaborative Protection Profile for Network Devices, Version 2.0 + Errata 20180314, Version 2.0, 14 March 2018 (NDcPP20E) That information has not been reproduced here and the NDcPP20E should be consulted if there is interest in that material. 6 Clarification of Scope All evaluations (and all products) have limitations, as well as potential misconceptions that need clarification.
