Description
Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. Remote access is access to DoD non-public VMMs by an authorized user (or another VMM) communicating through an external, non-organization-controlled network. Remote access methods include, for example, dial-up, broadband, and wireless. Encryption provides a means to secure the remote connection to prevent unauthorized access to the data traversing the remote access connection (e.g., RDP), thereby providing a degree of confidentiality. The encryption strength of mechanism is selected based on the security categorization of the information.

ℹ️ Check
Verify the VMM uses DoD-approved encryption to protect the confidentiality of remote access sessions. If it does not, this is a finding.

✔️ Fix
Configure the VMM to use DoD-approved encryption to protect the confidentiality of remote access sessions.
