Ensure PAM Enforces Password Requirements - Enforce for root User

An XCCDF Rule

Description

The pam_pwquality module's enforce_for_root parameter controls requirements for enforcing password complexity for the root user. Enable the enforce_for_root setting in /etc/security/pwquality.conf to require the root user to use complex passwords.

Rationale

Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password complexity is one factor of several that determines how long it takes to crack a password. The more complex the password, the greater the number of possible combinations that need to be tested before the password is compromised.
