a. Provide additional data origin authentication and integrity verification artifacts along with the authoritative name resolution data the system returns in response to external name/address resolution queries; and b.

What else in your programme already covers this

This control maps to 3 controls across 3 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.

FedRAMP High · 1 control

  • SC-20 Secure Name/Address Resolution Service (Authoritative)

FedRAMP Moderate · 1 control

  • SC-20 Secure Name/Address Resolution Service (Authoritative)

Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
