A well-structured computer incident response plan (CIRP) is crucial for protecting your organization from cyber threats. Here’s how to build one that works.

1. Form an Incident Response Team

Begin by assembling an incident response team (IRT) with clearly defined roles and responsibilities. This team should include IT staff, security experts, legal advisors, and communication specialists. Each member must be trained and well-prepared to handle various types of incidents, from data breaches to malware attacks. Regular training sessions and workshops can help keep the team’s skills sharp and up-to-date.

2. Identify and Classify Incidents

Develop criteria for identifying and classifying incidents based on their severity and potential impact on your organization. Incidents can be categorized into different levels, such as minor, significant, and critical.

For example, a phishing attempt might be considered minor, while a ransomware attack would be classified as critical. Having a clear classification system helps prioritize response efforts and allocate resources effectively.

3. Develop Detailed Response Procedures

Create detailed, step-by-step response procedures tailored to each type of incident. These procedures should cover the entire lifecycle of an incident, including initial detection, containment, eradication, and recovery.

For instance, if a data breach is detected, the procedure should include steps for isolating affected systems, contacting your breach coach, notifying stakeholders (including your insurer/broker, if you have cyber insurance), and conducting a thorough forensic investigation. Ensure these procedures are regularly updated to address emerging threats and vulnerabilities.

4. Implement Monitoring and Detection Systems

Utilize advanced monitoring tools and intrusion detection systems (IDS) to continuously monitor network traffic and identify suspicious activities in real-time. Regularly review logs, alerts, and system performance to spot potential incidents early.

Implementing automated monitoring solutions can significantly enhance your organization’s ability to detect and respond to threats promptly.

5. Establish Communication Protocols

Set up clear communication protocols for both internal and external stakeholders. This includes notifying affected parties, regulatory bodies, and the public when necessary.

Transparency is crucial during a cyber incident, as timely and accurate communication can help maintain trust and compliance. Create templates for different types of communications, such as incident notifications and status updates, to streamline the process during an incident.

6. Conduct Regular Training and Drills

Regularly train employees across the organization on recognizing and reporting security incidents. With your Breach Coach, conduct simulated incident response drills to test the effectiveness of your CIRP and identify areas for improvement.

These drills should mimic real-world scenarios and include all relevant stakeholders. After each drill, conduct a debriefing session to discuss what went well and what could be improved.

7. Maintain Documentation and Reporting

Keep thorough documentation of all incidents and response actions. This documentation is vital for post-incident analysis, legal compliance, and improving future response efforts.

Develop standardized reporting templates to ensure consistency and completeness. Detailed records can also aid in identifying patterns and trends, helping to prevent future incidents. 

These documentation and reports are also a legal requirements in many jurisdictions, including Quebec under Law25. Other jurisdictions are including this in proposed legislation and it is already a best practice. 

8. Review and Improve the CIRP

Your Breach Coach should regularly review and update your CIRP with you, based on lessons learned from actual incidents and training drills. Stay informed about new threats, vulnerabilities, and best practices by participating in cybersecurity forums, attending industry conferences, and subscribing to threat intelligence feeds. Incorporate these insights into your CIRP to ensure it remains relevant and effective.

Conclusion - computer incident response plan

An effective computer incident response plan is a cornerstone of your organization’s cybersecurity strategy. By forming a skilled incident response team, developing detailed response procedures, implementing robust monitoring systems, and maintaining open communication channels, you can significantly reduce the impact of cyber incidents. Regular training, thorough documentation, and continuous improvement will ensure your CIRP evolves alongside the ever-changing threat landscape.
