Fix Recommendation

Configure Amazon Linux 2023 to use "pwquality" to enforce password complexity rules.

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

password required pam_pwquality.so

Check Contents

Verify Amazon Linux 2023 uses "pwquality" to enforce the password complexity rules in the password-auth file with the following command:

$ grep pam_pwquality /etc/pam.d/password-auth
password required pam_pwquality.so

If the command does not return a line containing the value "pam_pwquality.so", or the line is commented out, this is a finding.

If the system administrator can demonstrate that the required configuration is contained in a PAM configuration file included or substacked from the system-auth file, this is not a finding.
