Vulnerability discussion

Without the use of multifactor authentication, the ease of access to privileged functions is greatly increased. 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). A privileged account is defined as an information system account with authorizations of a privileged user. 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).

Check content

Verify AAA Services are configured to require multifactor authentication using PIV credentials for authenticating privileged user accounts. Although the Common Access Card (CAC) is a PIV credential, it should not be used for privileged accounts, but rather only for non-privileged accounts. Administrative smart cards and tokens, separate from the CAC, are the preferred solution for privileged accounts. If AAA Services are not configured to require multifactor authentication using PIV credentials for authenticating privileged user accounts, this is a finding.

Fix text

Configure AAA Services to require multifactor authentication using PIV credentials for authenticating privileged user accounts. Although the CAC is a PIV credential, it should not be used for privileged accounts, but rather only for 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.
