The firewall implementation must use multifactor authentication for network access to privileged accounts.

Description
Multifactor authentication uses two or more factors to achieve authentication. Factors include: (i) something you know (e.g., password/PIN); (ii) something you have (e.g., cryptographic identification device, token); or (iii) something you are (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, Internet). Multifactor authentication provides strong protection for authentication mechanisms. Without a strong authentication method, the system is more easily breached by standard access control attacks.

Check Text ( C-45497r2_chk )
If authentication functionality is provided by the underlying platform's account management system or by a network authentication server rather than the firewall application itself, this is not a finding. Verify the configuration for the firewall requires access by multifactor authentication mechanisms (e.g., PKI, or DoD Alternate Token). If multifactor authentication is not used for network access to privileged accounts, this is a finding.

Configure all accounts accessing the firewall to use multifactor authentication (e.g., PKI or DoD Alternate Token).
