For organizations using both NIST guidance and ISO-governed incident-management structures. NIST SP 800-61r3 and ISO 27035 are compatible, but they frame incident response differently. NIST Rev. 3 is a CSF 2.0 community profile that spreads incident-response considerations across governance, preparation, response, recovery, and improvement. ISO 27035 stays closer to a formal incident-management process and governance structure. Teams should use those differences intentionally instead of forcing one vocabulary onto the other. ## The main difference is profile-based guidance versus process standardization SP 800-61r3 is organized around the CSF 2.0 Functions and categories. It is strongest when you want a broad cyber-risk-management model that connects incident response to governance, detection, communications, and recovery. ISO 27035 is stronger when you want a more formal incident-management process structure aligned with ISO management-system thinking. - NIST Rev. 3: community profile and recommendation set mapped to CSF 2.0 - ISO 27035: structured process and governance guidance across the series - Both can support one operating model if terminology differences are mapped carefully *Recommended next step* *Placement: after the comparison section* ## Use NIST SP 800-61r3 vs ISO/IEC 27035 as a cited research workflow Research Copilot can take NIST SP 800-61r3 vs ISO/IEC 27035 from how this topic compares with adjacent regulations or standards to a reusable workflow inside Sorena. Teams working on NIST SP 800-61r3 can keep owners, evidence, and next steps aligned without copying this guide into separate documents. - [Open Research Copilot for NIST SP 800-61r3 vs ISO/IEC 27035](/solutions/research-copilot.md): Start from NIST SP 800-61r3 vs ISO/IEC 27035 and answer scope, timing, and interpretation questions with cited outputs. - [Talk through NIST SP 800-61r3](/contact.md): Review your current process, evidence gaps, and next steps for NIST SP 800-61r3 vs ISO/IEC 27035. ## Operational depth differs in where it is expressed NIST Rev. 3 expresses operational depth through categories such as RS.MA, RS.AN, RS.CO, RS.MI, and RC.RP, plus linked external resources like SP 800-184 and CISA playbooks. ISO 27035 expresses depth more through its formal incident-management structure, governance expectations, and series-based decomposition. - Use NIST categories to organize tickets, playbooks, and evidence records - Use ISO governance language to align with wider ISMS and policy structures - Keep one shared severity, communication, and recovery model behind both ## Shared evidence works when you preserve both response detail and governance traceability Both frameworks benefit from a single evidence model containing incident timelines, decisions, communications, recovery records, and lessons learned. NIST adds strong emphasis on integrity and provenance of records and evidence. The same underlying artifacts can support both frameworks if they are tagged and packaged correctly. - Use one incident record with timestamps, owners, evidence links, and communication history - Preserve integrity and provenance for investigation actions, data, and metadata - Package the same artifacts differently for operational review versus formal audit or certification review ## A practical combined model uses one command system and one improvement loop The best combined model usually uses a single incident command structure, a single playbook library, and a single after-action process. NIST then provides the CSF 2.0-based organizing logic while ISO provides broader management-process discipline. This keeps teams fast during incidents and consistent during review. - Use one incident lead role, one escalation matrix, and one communications model - Use one remediation and lessons-learned backlog for both frameworks - Review mappings whenever Rev. 3, ISO 27035, or regulatory obligations change ## Primary sources - [NIST SP 800-61r3 - DOI](https://doi.org/10.6028/NIST.SP.800-61r3?ref=sorena.io) - Primary source for CSF 2.0-aligned incident response recommendations. - [NIST SP 800-61r3 publication page](https://csrc.nist.gov/pubs/sp/800/61/r3/final?ref=sorena.io) - Official source and supporting references. - [ISO/IEC 27035-1:2023 standard page](https://www.iso.org/standard/78973.html?ref=sorena.io) - ISO incident management principles and process baseline. ## Related Topic Guides - [NIST SP 800-61r3 Compliance Playbook | CSF 2.0 Incident Response](/artifacts/global/nist-sp-800-61-rev-3/compliance.md): Grounded incident-response playbook for NIST SP 800-61r3 covering the CSF 2.0 community-profile model, roles, risk-based incident management, communications. - [NIST SP 800-61r3 FAQ | Practical Incident Response Questions](/artifacts/global/nist-sp-800-61-rev-3/faq.md): Practical FAQ on NIST SP 800-61r3 covering what changed from r2, incident declaration, risk evaluation factors, containment versus observation. - [NIST SP 800-61r3 Incident Response Playbook Template](/artifacts/global/nist-sp-800-61-rev-3/incident-response-playbook-template.md): Grounded incident-response playbook template based on NIST SP 800-61r3 with incident criteria, incident lead, risk evaluation factors, communications tracks. - [NIST SP 800-61r3 Severity Classification and SLA Model](/artifacts/global/nist-sp-800-61-rev-3/severity-classification-and-sla-model.md): Grounded severity and SLA model for NIST SP 800-61r3 using NIST risk evaluation factors such as asset criticality, impact, scope, threat behavior. --- [Privacy Policy](https://www.sorena.io/privacy) | [Terms of Use](https://www.sorena.io/terms-of-use) | [DMCA](https://www.sorena.io/dmca) | [About Us](https://www.sorena.io/about-us) (c) 2026 Sorena AB (559573-7338).
