Questions people ask about transport layer security

What is Transport Layer Security?
A cryptographic protocol that secures communications over computer networks, widely used to protect web traffic, email, and other data transmissions.
Why is Transport Layer Security important for compliance?
Transport Layer Security is a key concept in Information Security. Understanding transport layer security helps organizations meet regulatory requirements, reduce risk, and demonstrate due diligence during audits. Our compliance platform maps 1,016 frameworks with 316K cross-framework control mappings.
Which compliance frameworks address Transport Layer Security?
Transport Layer Security appears in the requirement text of CCSDS 350.0-G-3 - Space Communications Security (Consultative Committee for Space Data Systems), Australian Information Security Manual, HL7 FHIR Security Framework, US Executive Order 14144 - Strengthening and Promoting Innovation in the Nation's Cybersecurity. Across these standards we have identified 4 controls that name it directly, each linked to the control text on the compliance platform.
