SC-7(17)—Automated Enforcement Of Protocol Formats
>Control Description
Enforce adherence to protocol formats.
>Cross-Framework Mappings
>Supplemental Guidance
System components that enforce protocol formats include deep packet inspection firewalls and XML gateways. The components verify adherence to protocol formats and specifications at the application layer and identify vulnerabilities that cannot be detected by devices operating at the network or transport layers.
