Ubuntu OS must be configured so that when passwords are changed or new passwords are established, pwquality must be used.

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.

Check Text (C-275656r1148018_chk)

Verify Ubuntu OS enforces password complexity rules by using the following command: $ grep -i enforcing /etc/security/pwquality.conf enforcing = 1 If "enforcing" is not "1", is commented out, or is missing, this is a finding. Check for the use of "pwquality" by using the following command: $ cat /etc/pam.d/common-password | grep requisite | grep pam_pwquality password requisite pam_pwquality.so retry=3 If "retry" is set to "0" or is greater than "3", or is missing, this is a finding.

Fix Text (F-79663r1148017_fix)

Configure Ubuntu OS to enforce password complexity rules. Add or modify the following line in the "/etc/security/pwquality.conf" file: enforcing = 1 Add or modify the following line in the "/etc/pam.d/common-password" file: password requisite pam_pwquality.so retry=3 Note: The value of "retry" should be between "1" and "3".
