| Description | ||||
| Pluggable authentication modules (PAM) allow for a modular approach to integrating authentication methods. PAM operates in a top-down processing model and if the modules are not listed in the correct order, an important security function could be bypassed if stack entries are not centralized. | ||||

Check Text (C-221667r1015164_chk)
Verify that /etc/pam.d/passwd is configured to use /etc/pam.d/system-auth when changing passwords:
# cat /etc/pam.d/passwd | grep -i substack | grep -i system-auth
password substack system-auth
If no results are returned, the line is commented out, this is a finding.
Fix Text (F-23371r419074_fix)
Configure PAM to utilize /etc/pam.d/system-auth when changing passwords.
