NIST vs SANS vs ISO 27035 vs the CISA playbook
The best framework is the one your organization can turn into assigned, practiced, and reviewable work. These references serve different needs and can be used together.
| Approach | Strong fit when | Practical role |
|---|---|---|
| NIST SP 800-61 Rev. 3 | You want adaptable guidance connected to NIST CSF 2.0. | Primary risk-informed incident response foundation. |
| SANS PICERL | Your responders want a memorable six-step tactical lifecycle. | Preparation, Identification, Containment, Eradication, Recovery, and Lessons Learned. |
| ISO/IEC 27035 | You operate globally or maintain an ISO-aligned management system. | Structured incident management principles and process. |
| CISA Federal Playbook | You need a standardized operational reference for federal environments. | Operational playbook and federal alignment reference. |
| Mapped hybrid | You face multiple regimes, customers, or operating models. | One primary operating model with mapped overlays. |
What makes a framework actionable?
A framework becomes useful when the plan names decision authority, assigns responsibilities, connects critical business services to recovery priorities, includes communication and reporting paths, and gives the team a clear way to record actions and lessons.
Five checks before you adopt one
- Can business, legal, communications, HR, IT, and security participants understand their next action?
- Can the approach accommodate your size, sector, systems, and third parties?
- Can you map insurer, customer, legal, and regulatory requirements into it?
- Can the team exercise the plan and record what needs to change?
- Can leadership see decisions, owners, recovery priorities, and evidence?
Incident response framework questions
Which incident response framework is best for most organizations?
NIST SP 800-61 Rev. 3 is a strong starting point for many organizations because it connects incident response to cybersecurity risk management through CSF 2.0. Your obligations and operating context may make SANS PICERL, ISO alignment, or a government playbook important as well.
What is the difference between NIST, SANS PICERL, and ISO 27035?
NIST connects incident response to CSF 2.0 risk management. SANS PICERL emphasizes a memorable six-step tactical lifecycle. ISO 27035 provides incident management principles and process suited to ISO-aligned management systems.
Can we use NIST and ISO 27035 together?
Yes. Use one as the primary operating foundation and map the other where it supports assurance, customer, or management-system needs.
Does a framework satisfy breach notification requirements?
No. Add applicable legal, regulatory, contractual, and insurance requirements to the plan. Consult qualified counsel for legal conclusions.
Should a small organization use the same framework as an enterprise?
The underlying outcomes can be similar, but the procedures, number of people, approval paths, and documentation should match the organization. One person may cover several functions in a small team.
