IR-04 incident documentation; AU-09 protection of audit information; AU-11 audit retention.

Gaps

Minor: CSF 2.0 emphasizes investigation record integrity and chain of custody. SP 800-53 covers audit protection but forensic record provenance less explicit.

Mapped Controls

RS.AN-07 Incident data and metadata are collected, and their integrity and provenance are preserved

Rationale

IR-04 incident data collection; AU-03 audit content; AU-09 protection; AU-11 retention.

Gaps

Minor: Metadata and provenance focus is more specific in CSF 2.0 than in SP 800-53.

RS.AN-08 An incident's magnitude is estimated and validated

Rationale

IR-04 incident analysis; IR-05 monitoring; RA-03 impact assessment.

Gaps

CSF 2.0 specifically addresses magnitude estimation. SP 800-53 covers through incident analysis.

Mapped Controls

RS.CO-02 Internal and external stakeholders are notified of incidents

Rationale

IR-06 incident reporting; IR-07 incident response assistance and coordination.

Gaps

Minimal gap.

Mapped Controls

RS.CO-03 Information is shared with designated internal and external stakeholders

Rationale

IR-06 reporting; PM-15 security contacts; PM-16 threat awareness sharing.

Gaps

Minor: CSF 2.0 emphasizes structured incident information sharing. SP 800-53 covers reporting but information sharing mechanisms less detailed.

Mapped Controls

RS.MA-01 The incident response plan is executed in coordination with relevant third parties once an incident is declared

Rationale

IR-04 incident handling; IR-06 reporting; IR-07 assistance; IR-08 response plan.

Gaps

Minimal gap.

RS.MA-02 Incident reports are triaged and validated

Rationale

IR-04 incident handling includes triage; IR-05 incident monitoring.

Gaps

Minimal gap.

Mapped Controls

RS.MA-03 Incidents are categorized and prioritized

Rationale

IR-04 incident handling includes categorization; IR-05 monitoring for tracking.

Gaps

Minor: CSF 2.0 emphasizes formal categorization and prioritization. SP 800-53 IR controls cover but with less categorization specificity.

Mapped Controls

RS.MA-04 Incidents are escalated or elevated as needed

Rationale

IR-04 incident handling; IR-06 reporting (includes escalation); IR-07 assistance.

Gaps

Minor: CSF 2.0 specifically addresses escalation procedures. SP 800-53 covers through incident reporting.

Mapped Controls

RS.MA-05 The criteria for initiating incident recovery are applied

Rationale

IR-04 incident handling includes recovery initiation; CP-10 system recovery.

Gaps

CSF 2.0 requires specific recovery initiation criteria. SP 800-53 covers recovery but formal criteria less explicit.

Mapped Controls

RS.MI-01 Incidents are contained

Rationale

IR-04 incident handling includes containment; SC-07 boundary protection for isolation.

Gaps

Minimal gap.

Mapped Controls

RS.MI-02 Incidents are eradicated

Rationale

IR-04 incident handling includes eradication; SI-03 malware removal.

Gaps

Minimal gap.

Mapped Controls

Methodology and Disclaimer

This coverage analysis maps from NIST CSF 2.0 clauses/requirements back to NIST SP 800-53 Rev 5 controls, assessing how well the SP 800-53 control set addresses each framework requirement.

Coverage weighting represents an informed estimate based on control-objective alignment, not a definitive compliance determination. Weightings consider whether SP 800-53 controls address the intent of each framework requirement, even where terminology and structure differ.

This analysis should be validated by qualified assessors for use in compliance or audit activities. The authoritative source for any compliance determination is always the framework itself.
