Discussion

Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. Remote access is access to DoD nonpublic information systems by an authorized user (or an information system) 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 thereby providing a degree of confidentiality. The encryption strength of mechanism is selected based on the security categorization of the information. Satisfies: SRG-APP-000014, SRG-APP-000015, SRG-APP-000039, SRG-APP-000219, SRG-APP-000439, SRG-APP-000440, SRG-APP-000441, SRG-APP-000442

A DoD approved VPN, or gateway/proxy, must be leveraged to access the Windows VDA from a remote network. This VPN, or gateway, must handle user authentication and tunneling of Citrix traffic. The VPN, or gateway, must meet the DoD encryption requirements, such as FIPS 140-2, for the environment.

If no VPN, or gateway/proxy, is used for remote access to the VDA, this is a finding.
If the VPN, or gateway/proxy, does not authenticate the remote user before providing access to the VDA, this is a finding.
If the VPN, or gateway/proxy, fails to meet the DoD encryption requirements for the environment, this is a finding.
