UBTU-22-254015 - Ubuntu 22.04 LTS must use the "SSSD" package for multifactor authentication services.

Information

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.

Solution

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
