The ALG providing user authentication intermediary services must use multifactor authentication for network access to non-privileged accounts.

Description

<VulnDiscussion>To assure accountability and prevent unauthenticated access, non-privileged users must utilize multifactor authentication to prevent potential misuse and compromise of the system. Multifactor authentication uses two or more factors to achieve authentication. Factors include: 1) Something you know (e.g., password/PIN), 2) Something you have (e.g., cryptographic, identification device, token), and 3) Something you are (e.g., biometric) Non-privileged accounts are not authorized access to the network element regardless of access method. Network access is any access to an application by a user (or process acting on behalf of a user) where said access is obtained through a network connection. Authenticating with a PKI credential and entering the associated PIN is an example of multifactor authentication. This requirement applies to ALGs that provide user authentication intermediary services.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
