Title

The TLS VPN Gateway must use TLS 1.2, at a minimum, to protect the confidentiality of sensitive data during transmission for remote access connections. (Cat I impact)

Discussion

Using older unauthorized versions or incorrectly configuring protocol negotiation makes the gateway vulnerable to known and unknown attacks that exploit vulnerabilities in this protocol. NIST SP 800-52 Rev2 provides guidance for client negotiation on either DoD-only or public-facing servers.

Check Content

Verify the TLS VPN Gateway is configured to use TLS 1.2 or higher to protect the confidentiality of sensitive data during transmission. If the TLS VPN Gateway does not use TLS 1.2, at a minimum, to protect the confidentiality of sensitive data during transmission, this is a finding.

Fix Text

Configure the TLS VPN Gateway to use TLS 1.2, at a minimum, to protect the confidentiality of sensitive data for transmission.
