CISA announced its paired Federal Government Cybersecurity Incident and Vulnerability Response Playbooks on November 16, 2021, to standardize coordinated response across Federal Civilian Executive Branch (FCEB) agencies. One playbook guides response to serious malicious cyber activity; the other addresses urgent and high-priority vulnerabilities. Both include processes and checklists, but they are federal guidance—not a substitute for an organization’s own plans or ongoing vulnerability management.
Why CISA released the playbooks
Section 6 of Executive Order 14028 directed the Department of Homeland Security, through CISA, to develop standard operational procedures for vulnerability and incident response involving FCEB information systems. CISA announced the paired playbooks on November 16, 2021, to help agencies coordinate actions, track mitigation across organizations, catalog incidents, and guide analysis and discovery.
The primary audience is FCEB agencies dealing with events affecting federal systems, data, and networks. The procedures are intended to support consistent response and communication between agencies; they do not mean every action or threshold applies unchanged in every environment.
How the two playbooks differ
| Playbook | When it applies | Main process | Relationship to other work |
|---|---|---|---|
| Incident Response | Confirmed malicious cyber activity when a major incident has been declared or cannot yet be reasonably ruled out. | Preparation; detection and analysis; containment; eradication and recovery; post-incident activities; coordination. | Organizes coordinated incident handling. CISA relates its process to NIST SP 800-61 Rev. 2. |
| Vulnerability Response | Urgent or high-priority vulnerabilities identified by an agency, CISA, industry partners, or others in the mission space. | Preparation; identification; evaluation; remediation; reporting and notification. | Supports response to significant vulnerabilities but does not replace a broader vulnerability management program. |
When the incident response playbook applies
The incident track is for confirmed malicious activity when a major incident has been declared or when that possibility has not yet been reasonably ruled out. Its phases take responders from preparation and detection through containment, eradication, recovery, post-incident work, and coordination. The process is meant to organize a multi-agency response; organizations still need to apply their own roles, technical procedures, and incident requirements.

How vulnerability response differs from vulnerability management
The vulnerability playbook provides a high-level process for handling urgent and high-priority vulnerabilities, from identification and evaluation to remediation and reporting or notification. It is not a complete day-to-day vulnerability management program. Routine discovery, prioritization, patching, and tracking remain part of an organization’s broader security operations.
The two tracks can intersect: investigating or remediating a vulnerability may reveal evidence of malicious activity. If that activity meets the incident playbook’s trigger, incident response may also be needed. The vulnerability process does not itself establish that a system has been compromised.

Can non-federal organizations use the playbooks?
Organizations outside the FCEB can adapt the practices and checklists, but should not assume federal roles, escalation paths, reporting thresholds, or technical steps fit their circumstances. State, local, territorial, and tribal agencies, critical-infrastructure operators, and private organizations should align any adaptation with their own systems, legal obligations, partners, and response plans. FEMA and CISA’s January 2024 guidance for emergency managers also describes using checklists to track activities through completion.

CISA’s official news listing records the original release on November 16, 2021. The indexed current PDF is stored under an August 2024 path, but that path alone does not establish a formal relaunch or a complete revision history, and it does not conclusively confirm that the file is the latest edition. CISA’s playbooks contain incident-response, preparation, and vulnerability-response checklists; use the official CISA playbook page or PDF to access them and verify the version available there.
