Link Encryption
What is Link Encryption?
Encryption of data at the data link layer that protects all traffic on a communication link, including headers and routing information.
Frameworks that govern link encryption
What the standards actually require on link encryption
Requirements naming link encryption across 2 standards, quoted from the control text.
Security Layer 1 Infrastructure per X.805 Clause 7.1: The Infrastructure Security Layer consists of network facilities (transmission facilities and network elements) protected by the security measures.

Why is Link Encryption important for compliance?
Link Encryption is a key concept in Information Security. Understanding link encryption helps organizations meet regulatory requirements, reduce risk, and demonstrate due diligence during audits. Our compliance platform maps 686 frameworks with 311K cross-framework control mappings.
Which compliance frameworks address Link Encryption?
Link Encryption appears in the requirement text of ITU-T X.805 - Security Architecture for End-to-End Communications, ITU Radio Regulations and Space Security Standards. Across these standards we have identified 3 controls that name it directly, each linked to the control text on the compliance platform.
