    Group
  • The Ubuntu operating system, for PKI-based authentication, must validate certificates by constructing a certification path (which includes status information) to an accepted trust anchor.

    <GroupDescription></GroupDescription>
    Group
  • The Ubuntu operating system must implement multifactor authentication for remote access to privileged accounts in such a way that one of the factors is provided by a device separate from the system gaining access.

    &lt;VulnDiscussion&gt;Using an authentication device, such as a CAC or token that is separate from the information system, ensures that even if the...
