Discussion

Inactive identifiers pose a risk to systems and applications because attackers may exploit an inactive identifier and potentially obtain undetected access to the system. Owners of inactive accounts will not notice if unauthorized access to their user account has been obtained. Operating systems need to track periods of inactivity and disable application identifiers after 35 days of inactivity.

Check Content

Ask the system administrator for the procedure to disable account identifiers (individuals, groups, roles, and devices) after 35 days of inactivity.

If there is no procedure this is a finding.

Fix Text

Develop a procedure to disable account identifiers (individuals, groups, roles, and devices) after 35 days of inactivity.
