Which document contains the Incident Handling Checklist?

The Incident Handling Checklist is found in NIST 800-61 Revision 2, which specifically focuses on "Computer Security Incident Handling Guide." This document provides comprehensive guidance on managing incidents effectively and includes best practices for responding to and recovering from security incidents.

NIST 800-61-2 outlines a structured approach to incident handling that encompasses preparation, detection and analysis, containment, eradication, recovery, and post-incident activity. The checklist itself serves as a practical tool to ensure that all necessary steps are followed during an incident response, making it essential for organizations to have a well-defined incident handling process.

The other documents listed serve different purposes: NIST 800-53 focuses on security and privacy controls, NIST 800-37 involves the risk management framework for information systems, and NIST SP 800-171 deals with protecting controlled unclassified information in non-federal systems. Therefore, the context and focus of the specified choices clarify why NIST 800-61-2 is the correct reference for the Incident Handling Checklist.
