Cisco 2621XM and Cisco 2651XM Modular Access Routers with AIM-VPN/EP FIPS 140-2 Non-Proprietary Security Policy

The Crypto Officer must disable IOS Password Recovery by executing the following commands:

configure terminal

no service password-recovery

end

show version

Once Password Recovery is disabled, administrative access to the module without the

Note

password will not be possible.

The Crypto Officer must perform the initial configuration. Cisco IOS version 12.3(3d) is the only

allowable image; no other image may be loaded.

The value of the boot field must be 0x0102. This setting disables break from the console to the ROM

monitor and automatically boots the Cisco IOS image. From the "configure terminal" command

line, the Crypto Officer enters the following syntax:

config-register 0x0102

The Crypto Officer must create the "enable" password for the Crypto Officer role. The password

must be at least 8 characters and is entered when the Crypto Officer first engages the "enable"

command. The Crypto Officer enters the following syntax at the "#" prompt:

enable secret <PASSWORD>

The Crypto Officer must always assign passwords (of at least 8 characters) to users. Identification

and authentication on the console port is required for Users. From the "configure terminal"

command line, the Crypto Officer enters the following syntax:

line con 0

password <PASSWORD>

The Crypto Officer shall only assign users to a privilege level 1 (the default).

The Crypto Officer shall not assign a command to any privilege level other than its default.

The Crypto Officer may configure the module to use RADIUS or TACACS+ for authentication.

Configuring the module to use RADIUS or TACACS+ for authentication is optional. If the module

is configured to use RADIUS or TACACS+, the Crypto-Officer must define RADIUS or TACACS+

shared secret keys that are at least 8 characters long.

If the Crypto Officer loads any IOS image onto the router, this will put the router into a non-FIPS

mode of operation.

There are two types of key management method that are allowed in FIPS mode: Internet Key

Exchange (IKE) and IPSec manually entered keys.

Although the Cisco IOS implementation of IKE allows a number of algorithms, only the following

algorithms are allowed in a FIPS 140-2 configuration:

ah-sha-hmac
