Check Text (C-271611r1091545_chk)

Verify that OL 9 uses "pwquality" to enforce the password complexity rules in the system-auth file with the following command: $ cat /etc/pam.d/system-auth | grep pam_pwquality 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.

Fix Text (F-75568r1091544_fix)

Configure OL 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
