Fix Recommendation

Configure Ubuntu 24.04 LTS to use "pwquality" to enforce password complexity rules.

Add the following line to "/etc/security/pwquality.conf" (or modify the line to have the required value):

enforcing = 1

Add the following line to "/etc/pam.d/common-password" (or modify the line to have the required value):

password requisite pam_pwquality.so retry=3

Note: Ensure the value of "retry" is between "1" and "3".

Check Contents

Verify that Ubuntu 24.04 LTS uses "pwquality" to enforce the password complexity rules.

Verify the pwquality module is being enforced by Ubuntu 24.04 LTS with the following command:

$ grep -i enforcing /etc/security/pwquality.conf
enforcing = 1

If the value of "enforcing" is not "1", or the line is commented out, this is a finding.

Check for the use of "pwquality" with the following command:

$ cat /etc/pam.d/common-password | grep requisite | grep pam_pwquality
password requisite pam_pwquality.so retry=3

If the value of "retry" is set to "0" or is greater than "3", or if a line is not returned, this is a finding.
