Discussion

Authentication for administrative (privileged-level) access to the device is required at all times. An account can be created on the device's local database for use when the authentication server is down or connectivity between the device and the authentication server is not operable. This account is referred to as the account of last resort because it is intended to be used as a last resort and when immediate administrative access is absolutely necessary. The account of last resort logon credentials must be stored in a sealed envelope and kept in a safe. The safe must be periodically audited to verify the envelope remains sealed. The signature of the auditor and the date of the audit should be added to the envelope as a record. Administrators should secure the credentials and disable the root account (if possible) when not needed for system administration functions.

Review the Nokia router configuration to verify a local account for last resort has been configured. 

Verify only one user (user of last resort) is listed in the response for this command:

- show system security user

If the Nokia router is not configured with only one local account to be used as the account of last resort in the event the authentication server is not available, this is a finding.
