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-274853r1106127_chk)

Verify Ubuntu 20.04 LTS has the packages required for multifactor authentication installed with the following command: $ dpkg -l | grep sssd ii sssd 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- metapackage ii sssd-ad 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- Active Directory back end ii sssd-ad-common 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- PAC responder ii sssd-common 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- common files ii sssd-ipa 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- IPA back end ii sssd-krb5 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- Kerberos back end ii sssd-krb5-common 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- Kerberos helpers ii sssd-ldap 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- LDAP back end ii sssd-proxy 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- proxy back end If the "sssd" package is not installed, this is a finding. The additional sssd components listed by the command may differ from configuration to configuration. Verify that "libpam-sss" (the PAM integration module for SSSD) is installed with the following command: $ dpkg -l | grep libpam-sss i libpam-sss:amd64 2.9.4-1.1ubuntu6.1 amd64 Pam module for the System Security Services Daemon Verify that "libnss-sss" (the NSS module for retrieving user and group information) is installed with the following command: $ dpkg -l | grep libnss-sss ii libnss-sss:amd64 2.9.4-1.1ubuntu6.1 amd64 Nss library for the System Security Services Daemon

Fix Text (F-78859r1101679_fix)

Install the sssd.service and the required pam packages with the following commands: $ sudo apt install sssd $ sudo apt install libpam-sss $ sudo apt install libnss-sss
