Incident Response Plan: Building Guidelines, Examples, and Templates

An incident response plan outlines how to detect, respond to, and limit the impact of security breaches. It guides organizations on how to handle events like data breaches, DDoS attacks, malware outbreaks, and insider threats.

So, why do you need an incident response plan? It minimizes the damage from security incidents, protecting your organization from operational, financial, and reputational harm. The plan defines incidents, outlines who’s responsible, and sets out critical steps to take when something goes wrong.

Creating an Incident Response Plan

  1. Draft a Policy
    Start by writing a policy that outlines incident response procedures. Get approval from senior executives to ensure that your team has the authority to act when needed. Keep this policy high-level and flexible; it should serve as a guiding document rather than a detailed manual.

  2. Build a Response Team
    Select a senior leader to oversee incident response. This person will direct a team of experts, with various roles depending on your organization’s size. A larger company might have multiple teams handling different regions, while smaller businesses could have a central team that draws from various departments. Train your team regularly and ensure everyone understands their responsibilities.

  3. Create Playbooks
    Playbooks provide detailed procedures for handling common incidents. For instance, if an employee loses a phone, follow a series of steps to wipe the device, verify encryption, report the theft, and replace the device. These templates streamline your response to specific incidents, eliminating guesswork.

  4. Establish a Communication Plan
    Coordinate communication among team members and external stakeholders during an incident. Include guidelines for involving law enforcement and decide who has the authority to make that call.

  5. Test the Plan
    Regularly test the incident response plan. Don’t wait for a real incident to see if it works. Run simulations based on various scenarios, from ransomware to insider threats, to make sure everyone knows their role.

  6. Learn from Every Incident
    After each incident, hold a review session to identify what went wrong and what could be improved. This allows your organization to patch security gaps and refine your response strategies for the future.

  7. Update Regularly
    Keep your plan dynamic. Reassess and revise it regularly, at least once a year or whenever there are significant changes in your infrastructure or business processes.

Incident Response Fundamentals
You don’t need to start from scratch. Use established frameworks like the NIST guidelines and SANS steps to build your policies. These frameworks offer roadmaps that define structured responses to incidents.

Having an incident response plan brings many benefits. It allows for faster detection and response to security threats, minimizes potential damage, and maintains regulatory compliance.

Using templates can help shape your response plan. Ensure it reflects your organization’s needs and seek feedback from various departments and local emergency responders for a comprehensive approach.

Remember, an effective incident response plan is not just a checklist; it’s a living document that evolves with your organization’s needs.
