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

Verify Ubuntu 22.04 LTS enforces a 60-day maximum password lifetime for new user accounts by using the following command: 
  
     $ grep -i pass_max_days /etc/login.defs 
     PASS_MAX_DAYS    60  
 
If "PASS_MAX_DAYS" is less than "60", is commented out, or is missing, this is a finding.

Fix Text

Configure Ubuntu 22.04 LTS to enforce a 60-day maximum password lifetime.  
  
Add or modify the following line in the "/etc/login.defs" file:  
  
PASS_MAX_DAYS    60
