Assessment Title
Rule Text
AOS must use Transport Layer Security (TLS) 1.2, at a minimum, to protect the confidentiality of sensitive data during electronic dissemination using remote access.
Description
Discussion Text
Using older unauthorized versions or incorrectly configuring protocol negotiation makes the gateway vulnerable to known and unknown attacks that exploit vulnerabilities in this protocol.
This requirement applies to TLS gateways (also known as Secure Sockets Layer [SSL] gateways). Application protocols such as Hypertext Transfer Protocol Secure (HTTPS), Secure File Transfer Protocol (SFTP), and others use TLS as the underlying security protocol and thus are in scope for this requirement. National Institute of Standards and Technology (NIST) Special Publication 800-52 provides guidance for client negotiation on either DoW-only or public-facing servers.
Satisfies: SRG-NET-000062, SRG-NET-000530
