Incident Monitoring, Reporting, and Response Assistance is the requirement that makes sure incidents are tracked, reported to the right people in time, and that users have somewhere to turn for help. Incident Handling (03.06.01) builds the capability to respond, and Incident Monitoring, Reporting, and Response Assistance (03.06.02) governs the record-keeping, reporting, and support around it. It has four (4) parts: track and document system security incidents, report suspected incidents to the organizational incident response capability within a defined time period, report incident information to defined authorities, and provide an incident response support resource that helps users handle and report incidents. Per the NIST discussion, documenting incidents supports forensics and trend analysis, and support resources include help desks, assistance groups, ticketing systems, and access to forensic services.
A common difficulty with this requirement is treating incident reporting as an internal-only activity and lacking a support resource for users. R3 adds an explicit objective to provide a support resource, which is new, and it ties reporting timeliness and reporting authorities to Organization-Defined Parameters (ODPs). For Department of Defense (DoD) contractors, both the reporting time period and the authorities are specified, and the reporting time period is essentially immediate.
Where things stand for companies facing the transition from NIST 800-171 R2 to R3:
The following is reproduced verbatim from NIST 800-171 R3, requirement 03.06.02 Incident Monitoring, Reporting, and Response Assistance. Only the formatting has been adjusted for readability. This requirement has four (4) lettered parts:
The source controls are IR-05, IR-06, and IR-07 from NIST 800-53. The bracketed assignments in parts b and c are the Organization-Defined Parameters (ODPs): the reporting time period and the reporting authorities. Per the NIST discussion, the types of incidents reported, the content and timeliness of reports, and the reporting authorities reflect applicable laws, directives, and contractual requirements, and 03.06.01 provides information on the types of incidents appropriate for monitoring. You can read the requirement directly at NIST 800-171 R3, 03.06.02 (p. 39).
Two (2) values sit inside this requirement. Depending on your contract, your organization may be permitted to define them. Organizations in the DIB subject to CMMC are not, because the DoD has defined them as policy.
The values below come from Attachment A of the DoD Chief Information Officer (CIO) memorandum dated 10 April 2025 (signed David W. McKeown). The memo identifies each parameter by requirement sub-part, while NIST 800-171A R3 identifies the same parameter by ODP number. Both identifiers appear below so you can match your System Security Plan (SSP) language to either document.
The memo states that its values "will be updated as necessary," so confirm against the current version before writing them into policy.
NIST 800-171A R3 breaks 03.06.02 into seven (7) assessment objectives: two (2) Organization-Defined Parameters (ODPs) and five (5) determination statements. These AOs are:
Part a splits into tracking and documenting incidents. If you are a DoD contractor, both ODPs are specified. Per the DoD-specified ODP values in ComplianceForge's NIST 800-171 R3 Transition Guide, the reporting time period (ODP[01]) is near real time or as soon as practicable upon discovery, and the reporting authorities (ODP[02]) are all applicable personnel and entities as specified by the contract and in accordance with any incident response plan notification procedures. The full guidance on assessment methods and objects, is in NIST 800-171A R3, 03.06.02 (p. 50).
Examine: incident response policy and procedures; procedures for incident monitoring; procedures for incident response assistance; incident response records and documentation; incident response plan; system security plan.
Interview: personnel with incident monitoring responsibilities; personnel with incident response assistance and support responsibilities; personnel with information security responsibilities.
Test: processes for incident reporting; incident monitoring capability; mechanisms for supporting or implementing the tracking and documenting of system security incidents; mechanisms for supporting or implementing incident reporting; mechanisms for supporting or implementing incident response assistance; processes for incident response assistance.
03.06.02 maps from NIST 800-171 R2 requirement 3.6.2 (track, document, and report incidents to designated officials and authorities both internal and external to the organization):
Mapped against the seven (7) AOs, five (5) are direct (minimal effort), one (1) is net new, and one (1) has no clear mapping, with the last two (2) categories both counting as significant effort. Tracking, documenting, and reporting carry forward, but the response-support resource and the defined reporting time period are the new work. Two of the seven (7) objectives are significant effort.
Source Controls in NIST 800-53 R5:
Secure Controls Framework (SCF) Crosswalk
Organizations running a single control set across multiple frameworks can satisfy 03.06.02 through the following SCF controls:
The crosswalks from NIST 800-171 R3 and NIST 800-171A R3 to the SCF are available at no cost through the SCF Set Theory Relationship Mapping (STRM): https://securecontrolsframework.com/start-here/set-theory-relationship-mapping-strm. The STRM also carries the relationship type for each mapping (Equal, Subset Of, Intersects With), which tells you whether an SCF control fully satisfies the requirement or only part of it. Mapping above taken from SCF 2026.3.
The following are issues teams may encounter rather than certainties. They are about the support resource and reporting timeliness, each of which needs documented evidence of due diligence and due care such as policies, standards, procedures, and configuration screenshots:
Reasonable objective evidence for an assessment is often subjective. The following examples of evidence to address NIST 800-171 R3 03.06.02 are sourced from the SCF Evidence Request List (ERL), available at https://securecontrolsframework.com/free-content/scf-download. These ERL artifacts are mapped to NIST 800-171 R3 03.06.02 through SCF controls. They establish a starting point for discussions on what an organization needs to have for evidence of due diligence and due care to withstand external scrutiny by an assessor or regulator.
Alongside these, keep the System Security Plan (SSP) narrative for 03.06.02 recording the ODP values you adopted.
With five (5) AOs mapping directly, one net new, and one with no clear mapping, 03.06.02 is a moderate lift. A realistic sequence:
What value does the DoD require for the first parameter in NIST 800-171 R3 03.06.02? R3 leaves the value to the organization. For the DIB, the DoD set it in the 10 April 2025 memorandum under ODP identifier 03.06.02.b: near real time or as soon as practicable upon discovery.
How many assessment objectives does NIST 800-171 R3 03.06.02 have? NIST 800-171A R3 breaks 03.06.02 into seven (7) assessment objectives: two (2) Organization-Defined Parameters (ODPs) and five (5) determination statements. An assessor works through each one separately, so each needs its own evidence.
Which NIST 800-53 R5 controls does NIST 800-171 R3 03.06.02 come from? IR-05, IR-06, IR-07.
Where does NIST 800-171 R3 03.06.02 sit in the NIST 800-171 R3 Kill Chain? Phase 10, Incident Response (IR). The Kill Chain is a phased model for sequencing R3 implementation, and it assigns this requirement to that phase.
03.06.02 Incident Monitoring, Reporting, and Response Assistance tracks and documents incidents, reports them to the incident response capability and to defined authorities within a defined time, and provides a support resource for users. It maps from R2 3.6.2 with tracking, documenting, and reporting transitioning directly, while the support resource is net new and the reporting time period has no R2 predecessor. The recurring problem is internal-only reporting with no user support. Define the reporting time and authorities (for DoD, near real time and as the contract specifies), track and document incidents, and provide a user-facing support resource.
