Check: GEN000700

SUSE Linux Enterprise Server v11 for System z STIG: GEN000700 (in versions v1 r12 through v1 r9)

Title

User passwords must be changed at least every 60 days. (Cat II impact)

Discussion

Limiting the lifespan of authenticators limits the period of time an unauthorized user has access to the system while using compromised credentials and reduces the period of time available for password-guessing attacks to run against a single password.

Check Content

Check the max days field (the 5th field) of /etc/shadow. # more /etc/shadow If the max days field is equal to 0 or greater than 60 for any user, this is a finding.

Fix Text

Set the max days field to 60 for all user accounts. # passwd -x 60 <user>
