Title

The /etc/pam_user.conf file must be owned by root. (Cat II impact)

Discussion

The /etc/pam_user.conf file is the per user configuration file for the Pluggable Authentication Module (PAM) architecture. It supports per user authentication, account, session, and password management. If the configuration is modified maliciously, users may gain unauthorized system access. The /etc/pam_user.conf file must not be configured unless it is required.

Check Content

If the system is configured for Trusted Mode, this check is not applicable. For SMSE: Verify the file is owned by root. # ls -lL /etc/pam_user.conf If the file is not owned by root, this is a finding.

Fix Text

If the system is operating in Trusted Mode, no fix is required. For SMSE: As root, change the file ownership. # chown root /etc/pam_user.conf
