Discussion

Any password, no matter how complex, can eventually be cracked. Therefore, passwords need to be changed periodically. If the operating system does not limit the lifetime of passwords and force users to change their passwords, there is the risk that the operating system passwords could be compromised.

Check Content

Check the max days field of /etc/shadow by running the following command:

# cat /etc/shadow | cut -d':' -f1,5 | egrep -v "([0|60])" | grep -v ":$"

If any results are returned, this is a finding.

Fix Text

Set the maximum time period between password changes for each [USER] account to "60" days. The command in the check text will give you a list of users that need to be updated to be in compliance.

# passwd -x 60 [USER]

The DoD requirement is "60" days.
