User passwords must be changed at least every 60 days.


Overview

Finding ID Version Rule ID IA Controls Severity
V-38479 RHEL-06-000053 SV-50279r1_rule Medium
Description
Setting the password maximum age ensures users are required to periodically change their passwords. This could possibly decrease the utility of a stolen password. Requiring shorter password lifetimes increases the risk of users writing down the password in a convenient location subject to physical compromise.
