The AIX operating system must be configured to use Multi Factor Authentication for remote connections.
An XCCDF Rule
Description
<VulnDiscussion>To assure accountability and prevent unauthenticated access, privileged and 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). The DoD CAC with DoD-approved PKI is an example of multifactor authentication.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
