Introduction Purpose This document is a nonproprietary Cryptographic Module Security Policy for the Enterasys Networks XSR-1805, XSR-1850, and XSR-3250 appliances. This security policy describes how the XSR-1805, XSR-1850, and XSR-3250 meet the security requirements of FIPS 140-2 and how to run the modules in a secure FIPS 140-2 mode. This policy was prepared as part of the Level 2 FIPS 140-2 validation of the module. FIPS 140-2 (Federal Information Processing Standards Publication 1

ENTERASYS NETWORKS XSR-1805, XSR-1850, AND XSR-3250 Overview Part of the Enterasys Networks X-Pedition Security Router (XSR) series, the XSR-1805, XSR-1850, and XSR-3250 modules are networking devices that combine a broad range of IP routing features, a broad range of WAN interfaces and a rich suite of network security functions, including site-to-site and remote access VPN connectivity and policy managed, stateful-inspection firewall functionality. The XSR-18xx modules were designed to

ideal to support mission- critical applications extending to the branch office. The XSR-3250 offers nearly ten times the performance speed of the XSR- 1850 and approximately 15 times more VPN tunnels. Coupling these features with the six network interface module (NIM) slots makes the XSR- 3250 ideally suited to a regional office required to terminate up to six T3/E3 or 24 T1/E1 connections. A redundant power supply is included. The features of each XSR module are summarized in Table 1. XS

The hardware components for the XSR-18xx modules vary slightly to meet the performance level for each module. The XSR-1850 is an enhancement of the XSR-1805 consisting of the following additional features: • Two fans • External power source connector • One PMC slot for PPMC card • 19” 1.5 U rack-mount chassis • 64 MB of DRAM Due to the large difference in performance levels, the XSR-3250 hardware components vary quite significantly, when compared to the XSR-18xx modules. The main d

Roles and Services 1 The module supports role-based and identity-based authentication . There are two main roles in the module (as required by FIPS 140-2) that operators may assume: a Crypto Officer role and User role. Crypto Officer Role The Crypto Officer role has the ability to configure, manage, and monitor the module. Three management interfaces can be used for this purpose: • CLI – The Crypto Officer can use the CLI to perform non-security- sensitive and security-sensitive monitor

• Read-only Crypto Officer – Management users with privilege level zero assume the Read-only Crypto Officer role. The Read-only Crypto Officer can only issue monitoring commands with low security level. Examples of commands are: show version and show clock. Descriptions of the services available to the Crypto Officer role are provided in the table below.

mechanism is as strong as the RSA algorithm using a 1024 bit key pair. Pre-shared key-based User HMAC SHA-1 generation and verification is authentication (IKE) used to authenticate to the module during IKE with preshared keys. This mechanism is as strong as the HMAC with SHA-1 algorithm. Additionally, preshared keys must be at least six characters long. Even if only uppercase letters were used without repetition for a six character preshared key, the probability of randomly guessing th

If the master encryption key is generated within the module, the module outputs the key to the console as soon as the key is generated in order for the Crypto Officer to note down and store the key securely outside of the module. This is required, since the Crypto Officer must enter the current key before changing or removing it. The master secret key can only be configured through the serial console or over an SSH tunnel.

Self-Tests The module performs a set of self-tests in order to ensure proper operation in compliance with FIPS 140-2. These self-tests are run during power-up (power-up self-tests) or when certain conditions are met (conditional self-tests). Power-up Self-tests: • Software integrity tests: the modules use an EDC, in the form of an MD5 checksum, to check the integrity of its various components • Cryptographic algorithm tests: o AES-CBC KAT o DES-CBC KAT o Triple-DES-CBC KAT o PR
