This Incident Response Plan (IRP) is a living, operational document used to prepare for, respond to, and learn from security incidents. It is designed to be completed and maintained on a per‑customer basis and referenced during active incidents.
Phase 1 must be completed in full for each customer before this document is considered usable.
Phase 1 establishes:
Phase 1 defines who responds, how decisions are made, and what tools are available during an incident.
An incomplete Phase 1 will significantly slow response efforts.
For the first revision, Phase 2 should be reviewed and partially completed to ensure responder awareness.
At minimum, document:
The objective is familiarity, not execution. Responders should understand how an incident is detected and validated before handling a live event.
Once an incident is identified:
This IRP should be used as both a reference guide and a record of response activities.
Following incident resolution:
This IRP should be reviewed and updated:
This document should always reflect the current operational state of the customer’s environment.
Preparation is the foundation of an effective incident response process. It involves establishing policies, teams, and tools to ensure a rapid and coordinated response to security incidents.
A well-defined response team ensures that incidents are handled efficiently, reducing confusion and delays during a crisis.
Identify and assign roles:
Document team contact information and escalation procedures:
Ensure legal, HR, and executive management are aware of their responsibilities:
A documented IRP provides a structured approach to incident response, ensuring consistency and compliance with security best practices.
Define policies, procedures, and response playbooks for different incident types:
Align the IRP with organizational security policies and regulatory requirements:
Ensure stakeholders are trained and understand the plan:
Clear communication protocols prevent misinformation and ensure that the right stakeholders are informed at the right time.
Identify internal communication channels for incident response:
Establish external notification protocols for regulatory compliance:
Define the escalation process for leadership and law enforcement involvement:
Having the right tools in place allows for efficient detection, analysis, and response to security threats.
Maintain a list of forensic and security tools:
Ensure security logs are centrally stored and accessible:
Validate chain-of-custody compliance:
Regular testing ensures the incident response plan remains relevant and effective.
Conduct regular testing:
Update response plans as needed:
Ensure backups are tested and securely stored:
Detection and analysis focus on identifying security incidents, assessing severity, and determining appropriate response actions.
Early detection helps mitigate potential damage.
Accurate classification ensures proper resource allocation.
Understanding impact enables better prioritization.
Proper evidence handling is critical for forensics and legal actions.
This phase focuses on stopping spread, eliminating root cause, and restoring operations.
Containment prevents further damage.
Complete eradication prevents reoccurrence.
Restoration ensures safe resumption of operations.
Ongoing monitoring ensures full remediation.
Post-incident review enables continuous improvement.
A structured review identifies opportunities for improvement.
Continuous updates strengthen security posture.
Sharing insights improves awareness and resilience.
