Details

In the event the authentication server is unavailable, the network device must have a single local account of last resort defined.

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.

Solution

Configure the device to only allow one local account of last resort for emergency access and store the credentials in a secure manner.
