Vulnerability 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 since 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.

Check content

Review the network device configuration to determine if there is more than one account enabled Verify that the account of last resort is configured with the privileges needed to perform privileged functions when the authentication server is not available. Verify default admin and other vendor-provided accounts are disabled, removed, or renamed where possible. Verify the username and password for the account of last resort is contained within a sealed envelope and kept in a safe. Check the log to verify periodic auditing has occurred. If one local account does not exist for use as the account of last resort, this is a finding.

Fix text

Configure the device to only allow one local account for use as the account of last resort.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
