Description
Without the use of multifactor authentication, the ease of access to privileged functions is greatly increased. Multifactor authentication requires using two or more factors to achieve authentication. Factors include: 1) Something a user knows (e.g., password/PIN); 2) Something a user has (e.g., cryptographic identification device, token); and 3) Something a user is (e.g., biometric). A privileged account is defined as an information system account with authorizations of a privileged user. Network access is defined as access to an information system by a user (or a process acting on behalf of a user) communicating through a network (e.g., local area network, wide area network, or the internet). The DOD common access card (CAC) with DOD-approved PKI is an example of multifactor authentication.

Check Text (C-274854r1106129_chk)

Verify the "sssd.service" is enabled and active with the following commands: $ sudo systemctl is-enabled sssd enabled $ sudo systemctl is-active sssd active If "sssd.service" is not active or enabled, this is a finding.

Fix Text (F-78860r1106128_fix)

Enable the "sssd.service" to start automatically on reboot with the following command: $ sudo systemctl enable sssd.service ensure the "sssd" service is running $ sudo systemctl start sssd.service
