SC-08 Transmission Integrity
Control: The information system protects the integrity of transmitted information.
Supplemental Guidance: If the organization is relying on a commercial service provider for transmission services as a commodity item rather than a fully dedicated service, it may be more difficult to obtain the necessary assurances regarding the implementation of needed security controls for transmission integrity. When it is infeasible or impractical to obtain the necessary security controls and assurances of control effectiveness through appropriate contracting vehicles, the organization either implements appropriate compensating security controls or explicitly accepts the additional risk. NIST Special Publication 800-52 provides guidance on protecting transmission integrity using Transport Layer Security (TLS). NIST Special Publication 800-77 provides guidance on protecting transmission integrity using IPsec. NIST Special Publication 800-81 provides guidance on Domain Name System (DNS) message authentication and integrity verification. NSTISSI No. 7003 contains guidance on the use of Protective Distribution Systems.
(1) The organization employs cryptographic mechanisms to recognize changes to information during transmission unless otherwise protected by alternative physical measures.
Enhancement Supplemental Guidance: Alternative physical protection measures include, for example, protected distribution systems.
