Description
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. Satisfied: SRG-OS-000480-GPOS-00229, SRG-OS-000069-GPOS-00037

ℹ️ Check
Verify the operating system uses "pwquality" to enforce the password complexity rules. Check for the use of "pwquality" with the following command: # cat /etc/pam.d/system-auth \| grep pam_pwquality password requisite pam_pwquality.so retry=3 If the command does not return an uncommented line containing the value "pam_pwquality.so" as shown, this is a finding. If the value of "retry" is set to "0" or greater than "3", this is a finding.

✔️ Fix
Configure the operating system to use "pwquality" to enforce password complexity rules. Add the following line to "/etc/pam.d/system-auth" (or modify the line to have the required value): password requisite pam_pwquality.so retry=3 Note: The value of "retry" should be between "1" and "3".
