| Multifactor authentication requires using two or more factors to achieve authentication. Factors include:
(i) something a user knows (e.g., password/PIN);
(ii) something a user has (e.g., cryptographic identification device, token); or
(iii) something a user is (e.g., biometric).
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., LAN, WAN, or the Internet).
DoD has mandated the use of the Common Access Card (CAC) token/credential to support identity management and personal authentication for systems covered under HSPD 12. DoD recommended architecture for network devices is for system administrators to authenticate using an authentication server using the DoD CAC credential with DoD-approved PKI.
This requirement also applies to the account of last resort and the root account only if non-local access via the network is enabled for these accounts (not recommended). |
