UBTU-16-010210
(in version v1 r2)
Title
Passwords for new users must have a 24 hours/1 day minimum password lifetime restriction. (Cat II impact)
Discussion
Enforcing a minimum password lifetime helps to prevent repeated password changes to defeat the password reuse or history enforcement requirement. If users are allowed to immediately and continually change their password, then the password could be repeatedly changed in a short period of time to defeat the organization's policy regarding password reuse.
Check Content
Verify that the Ubuntu operating system enforces a 24 hours/1 day minimum password lifetime for new user accounts by running the following command: # grep -i pass_min_days /etc/login.defs PASS_MIN_DAYS 1 If the "PASS_MIN_DAYS" parameter value is less than or equal to "1", or commented out, this is a finding.
Fix Text
Configure the Ubuntu operating system to enforce a 24 hours/1 day minimum password lifetime. Add, or modify the following line in the "/etc/login.defs" file: PASS_MIN_DAYS 1
