Overview

This comparison helps teams mapping NIST SP 800-161 Rev. 1 to DORA ICT third-party risk. The goal is not to pick a winner; it is to separate scope, owners, evidence, review cadence, and assurance so one implementation record can support both sides without overclaiming.

Review all sources

First framework

NIST SP 800-161 Rev. 1

NIST SP 800-161 Rev. 1 is the primary scoping column: use it to confirm covered facts, accountable owners, mandatory artifacts, timing, and enforcement exposure before assigning implementation work.

Second framework

DORA ICT third-party risk

DORA ICT third-party risk is the second workstream in this comparison. Use it to test where the comparator has different scope, owners, triggers, evidence, timing, enforcement, and reuse limits from NIST SP 800-161 Rev. 1.
