Check Text ( C-89557r1_chk )
Check "/etc/pam.d/common-password" for "pam_cracklib" configuration: # grep pam_cracklib /etc/pam.d/common-password* If "pam_cracklib" is not present, this is a finding. Ensure the "passwd" command uses the "common-password" settings. # grep common-password /etc/pam.d/passwd If a line "password include common-password" is not found then the "password checks in common-password" will not be applied to new passwords, this is a finding.

Check Text ( C-89557r1_chk )

Check "/etc/pam.d/common-password" for "pam_cracklib" configuration:

# grep pam_cracklib /etc/pam.d/common-password*

If "pam_cracklib" is not present, this is a finding.

Ensure the "passwd" command uses the "common-password" settings.

# grep common-password /etc/pam.d/passwd

If a line "password include common-password" is not found then the "password checks in common-password" will not be applied to new passwords, this is a finding.

Fix Text (F-96607r1_fix)
Edit "/etc/pam.d/common-password" and configure "pam_cracklib" by adding a line such as "password requisite pam_cracklib.so"
