Vulnerability discussion

Inactive identifiers pose a risk to network devices. Attackers that are able to exploit an inactive identifier can potentially obtain and maintain undetected access to the device. Owners of inactive accounts may not notice if unauthorized access to their account has been obtained. Network devices need to track periods of inactivity and disable application identifiers after 35 days of inactivity.This control does not apply to the account of last resort or root account. DoD prohibits local user accounts on the device, except for an account of last resort and (where applicable) a root account.

Check content

Determine if the network device disables identifiers after 35 days of inactivity for all local identifiers except for the account of last resort or root account. For non-local accounts, verify that the device is configured to use an authentication server. If the network device does not have the capability to automatically disable or remove identifiers after 35 days of inactivity, this is a finding.

Fix text

Configure the network device or its associated authentication server to disable identifiers after 35 days of inactivity. For remote logon using the authentication server, configure this capability on the authentication server. Disable or remove unauthorized local identifiers, except for the account of last resort and the root account.

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.
