Agencies must at a minimum put the following into their IRP: broad guidance on what counts as an information security incident; the lowest acceptable level of training in incident response and investigation for system administrators and system users; who has the authority to start investigations of an incident; the steps needed to preserve the integrity of evidence supporting an incident; the steps needed to keep critical systems operating; when and how incidents are to be formally reported; and the national policy requirements for incident reporting (the control refers to Chapter 7, Information Security Incidents).
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
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.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
