Check Text (C-258098r1045195_chk)

Verify RHEL 9 uses "pwquality" to enforce the password complexity rules in the system-auth file with the following command: $ grep pam_pwquality /etc/pam.d/system-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 (SA) 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.

Fix Text (F-61763r926280_fix)

Configure RHEL 9 to use "pwquality" to enforce password complexity rules. Add the following line to the "/etc/pam.d/system-auth" file(or modify the line to have the required value): password required pam_pwquality.so
