OL 8 must ensure the password complexity module is enabled in the system-auth file.
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. "pwquality" enforces complex password construction configuration and has the ability to limit brute-force attacks on the system.
OL 8 utilizes "pwquality" as a mechanism to enforce password complexity. This is set in both:
