Systems administrators are responsible for keeping systems secure and safe from hackers. Part of this process is enabling password restrictions, so that users are forced to change their password on a regular basis. In this lab, we will learn to set password restrictions for Linux users. We will set passwords to warn users of required password changes 7 days in advance, require password changes every 30 days, and lock the passwords after 60 days of account inactivity.
