Description
Authentication for administrative access to the device is required at all times. A single account of last resort can be created on the device's local database for use in an emergency such as when the authentication server is down or connectivity between the device and the authentication server is not operable. The console or local account of last resort logon credentials must be stored in a sealed envelope and kept in a safe.

Check Text ( C-12936r5_chk )
Review the network device configuration to determine if an authentication server is defined for gaining administrative access. If so, there must be only one local account of last resort configured locally for an emergency. Example: [edit system] class tier3 { idle-timeout 15; permissions all; } user admin { full-name Administrator; uid 2000; class tier3; authentication { encrypted-password xxxxxxxxxxx; } } Verify the username and password for the local account of last resort is contained within a sealed envelope kept in a safe. If an authentication server is used and more than one local account exists, this is a finding.
