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.
