The application must use multifactor (Alt. Token) authentication for network access to privileged accounts.

Description

<VulnDiscussion>Multifactor authentication requires using two or more factors to achieve authentication and access. 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). Multifactor authentication decreases the attack surface by virtue of the fact that attackers must obtain two factors, a physical token or a biometric and a PIN, in order to authenticate. It is not enough to simply steal a user's password to obtain access. A privileged account is defined as an information system account with authorizations of a privileged user. An Alt. Token is a separate CAC like token used specifically for administrative account access and serves as a separate identifier much like a separate user account. 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).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
