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.
Successfully complete this lab by achieving the following learning objectives:
- List the User Account Aging Information for the cloud_user User Account
chage -l cloud_user
- Give the user 7 days warning that a password change is equired
This is set by default, so no changes are needed.
- Set the Maximum Days between Password Changes to 30 Days
chage -M 30 cloud_user
- Set the Account to Lock upon 60 Days of Inactivity after a Password Has Expired
chage -I 60 cloud_user
