Vulnerability discussion

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:(i) Something you know (e.g., password/PIN);(ii) Something you have (e.g., cryptographic identification device, CAC/SIPRNet token); or(iii) Something you are (e.g., biometric).A non-privileged account is any information system account with authorizations of a non-privileged user.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.Applications integrating with the DoD Active Directory and utilize the DoD CAC are an example of compliant multifactor authentication solutions.

Check content

Review the application documentation and interview the application administrator to identify application access methods. If the application is not PK-enabled due to the hosted data being publicly releasable, this check is not applicable. Ask the application administrator to log on to the application. Have the application admin use their non-privileged credentials. Validate the application prompts the user to provide a certificate from the CAC. Validate the application requests the user to input their CAC PIN. If the application allows access without requiring a CAC or Alt. Token, this is a finding.

Fix text

Configure the application to require CAC or Alt. Token authentication for non-privileged network access to non-privileged accounts.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
