Maintain a written security incident response plan covering the definition and classification of security incidents, reporting policies and procedures, internal and external communication and information sharing, and hand off and escalation points, and test it at a frequency determined by an appropriate risk analysis and no less frequently than annually for covered entities.
CFTC System Safeguards (17 CFR 37, 38, 39, 49) CFTC-SS-16 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of CFTC System Safeguards (17 CFR 37, 38, 39, 49) your existing evidence covers. Hold NIST Cybersecurity Framework 2.0 and 28 of 39 CFTC System Safeguards (17 CFR 37, 38, 39, 49) controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 5 were rejected on the NIST Cybersecurity Framework 2.0 pair alone.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
