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 CAC with DoD-approved PKI is an example of multifactor authentication.

Verify the Ubuntu operating system uses multifactor authentication for local access to accounts. Check that the "pam_pkcs11.so" option is configured in the "/etc/pam.d/common-auth" file with the following command: # grep pam_pkcs11.so /etc/pam.d/common-auth auth [success=2 default=ignore] pam_pkcs11.so If "pam_pkcs11.so" is not set in "/etc/pam.d/common-auth", this is a finding. |

Configure the Ubuntu operating system to use multifactor authentication for local access to accounts. Add or update "pam_pkcs11.so" in "/etc/pam.d/common-auth" to match the following line: auth [success=2 default=ignore] pam_pkcs11.so |
