Description
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 a VMM account with authorizations of a privileged user. Network access is defined as access to a VMM 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). The DoD CAC with DoD-approved PKI is an example of multifactor authentication.

ℹ️ Check
Verify the VMM uses multifactor authentication for network access to privileged accounts. If it does not, this is a finding.

✔️ Fix
Configure the VMM to use multifactor authentication for network access to privileged accounts.
