SV-65617r1_rule The operating system must automatically audit account disabling actions.

Vulnerability discussion

When accounts are disabled, user accessibility is affected. Accounts are utilized for identifying individual application users or for identifying processes themselves. In order to detect and respond to events affecting user accessibility and operating system processing, the operating system must audit account disabling actions and, as required, notify the appropriate individuals, so they can investigate the event. Such a capability greatly reduces the risk that accessibility will be negatively affected for extended periods of time and provides logging that can be used for forensic purposes.

Check content

In order to view the currently configured flags for the audit daemon, run the following command: sudo grep ^flags /etc/security/audit_control | sed 's/flags://' | tr "," "\n" | grep ad The account creation events are logged by way of the "ad" flag. If "ad" is not listed in the result of the check, this is a finding.

Fix text

To make sure the appropriate flags are enabled for auditing, run the following command: sudo sed -i.bak '/^flags/ s/$/,ad/' /etc/security/audit_control

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.
