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

At the command line, run the following command:

# grep "^PASS_MAX_DAYS" /etc/login.defs

Fix Text

Navigate to and open:

/etc/login.def

Modify the "PASS_MAX_DAYS" line to the following: 

PASS_MAX_DAYS   90
