NIST 800-53 IR (Incident Response) Family Explained

Controls (SP 800-53 Revision 5 — IR-1 through IR-10)

Practical Reading Order

Policy and plan (IR-1, IR-8) → train and test (IR-2, IR-3) → handle, monitor, and report (IR-4–IR-6) → assistance and specialty (IR-7, IR-9, IR-10).

Relate to SP 800-61 Rev 3 and CSF Detect / Respond / Recover — IR is the control catalog; 800-61 and CSF supply process narrative.

Frequently Asked Questions

Is IR-10 required in every baseline?

Check SP 800-53B for your impact level. Not every IR control appears in the Low baseline.

Does IR replace SP 800-61?

No. The IR family is the control catalog. SP 800-61 supplies incident response process narrative.

What is information spillage versus a cyber incident?

IR-9 addresses information spillage specifically. Broader cyber incidents are handled under IR-4 through IR-8.
