Fix Recommendation

Configure the operating system to implement multifactor authentication for remote access to privileged accounts via pluggable authentication modules (PAM).

Modify all of the services lines in "/etc/sssd/sssd.conf" or in configuration files found under "/etc/sssd/conf.d" to include pam.

Check Contents

Verify the operating system implements multifactor authentication for remote access to privileged accounts via pluggable authentication modules (PAM).

Check the "/etc/sssd/sssd.conf" file for the authentication services that are being used with the following command:

# grep services /etc/sssd/sssd.conf /etc/sssd/conf.d/*.conf

services = nss, pam

If the "pam" service is not present on all "services" lines, this is a finding.
