No organization is immune to cyberthreats. 75% of organizations experienced at least one ransomware attack in 2023, meaning having a robust Incident Response Plan (IRP) is no longer optional — it’s a necessity. An incident response plan acts as your organization’s defense playbook, ensuring a swift, coordinated response to mitigate damage, minimize downtime, and protect sensitive data.
This guide will provide you with actionable recommended steps to develop, implement, and optimize your incident response plan, helping you stay prepared for incidents while maintaining business continuity.
What Is an Incident Response Plan?
An Incident Response Plan (IRP) is a documented strategy outlining the procedures and protocols an organization must follow when responding to a cybersecurity incident. These incidents could include ransomware attacks where threat actors disable systems or files by encrypting them and requesting a ransom. Other incidents could include exfiltration of data followed by extortion demanding payment for not making data public.
The primary goals of an IRP are to:
- Proceed systematically with defined steps
- Limit the damage caused by an incident.
- Make sure stakeholders are kept inform and there are clear communication channels
- Expedite recovery and minimize downtime.
- Protect sensitive data and ensure compliance with regulations.
Why Is an Incident Response Plan Important?
Cyberattacks are becoming more sophisticated, according to the Q3 Coveware adversary TTP report, 96% of cyberattacks involving encryption and 76% exfiltration of data. Without a clear plan in place, organizations may face prolonged downtime, significant financial losses, and irreversible reputational damage. An effective IRP provides several benefits:
- Swift Action: Reduces confusion and delays by providing clear step-by-step guide for responding to incidents.
- Legal and Regulatory Compliance: Ensures proper documentation and preservation of digital evidence, demonstrates due diligence and adherence to laws and regulations such as GDPR, HIPAA, or the CIRCIA 72-hour reporting mandate.
- Minimized Impact: Plan to contain and reduce the time systems are offline or compromised during an attack, in this way the incident response plan reduces financial and operational impact.
- Improved Communication: Streamlines coordination between IT, security, operations, and legal teams.
Key Elements of an Incident Response Plan
A successful IRP follows a structured lifecycle. Based on the National Institute of Standards and Technology (NIST) framework, here are the six essential phases of an incident response plan:
1. Preparation
Preparation is the foundation of an effective IRP. It involves:
- Defining the roles and responsibilities of your incident response team (IRT) as well as communication strategy. Prepare list of contacts from third party vendors for assistance during an incident.
- Conducting cybersecurity training, social engineering, and phishing awareness programs.
- Using monitoring tools like endpoint detection and response (EDR), firewalls, and vulnerability scanners.
- Ensuring there are periodic backups and making sure backup and recovery are tested regularly.
- Implementing Zero Trust and Secure by Design principles such as least privilege, network segmentation and multi-factor authentication.
- Identifying critical systems and potential impact, then prioritizing them for potential recovery actions.
2. Detection and Analysis
Timely identification of a cybersecurity incident is critical. Identify disruption or unusual activity including data transfers and account changes. Monitor supply chain partners (customers, vendors or partners) for reports of possible exploited vulnerabilities and ransomware attacks. Implement solutions that:
- Monitor network traffic and endpoint activity for unusual behavior.
- Use threat intelligence platforms to identify potential threats.
- Document incidents with timestamps and evidence for analysis.
3. Containment
The goal of containment is to isolate the threat to prevent further damage. Strategies include:
- Segregating infected systems from the network.
- Limiting access to compromised user accounts.
- Resetting passwords and other forms of authentication specially for administrators.
- Leveraging automated workflows for immediate containment.
- Collecting log and audit files for forensic analysis
4. Eradication
Once the threat is contained, the eradication phase involves:
- Identifying and eliminating the root cause (e.g., malware, phishing emails).
- Patching vulnerabilities or misconfigurations exploited by the attacker.
- Performing forensic analysis to prevent recurrence.
- If needed, reinstalling the affected systems.
- Updating antivirus signatures so that the identified malware is blocked on the next attempt to infect.
5. Recovery
Restoring normal operations is the focus of this phase. It includes:
- Validating clean backups before restoring from backups
- Quarantining data in clean rooms isolated from production until the data is clean without malware and ready for recovery in production
- Consulting with exports on ransomware incident response
- Trying to decrypt data, check if there are known decryption keys.
- Restoring encrypted or compromised servers or systems from a clean backup.
- Testing and verifying whether the abnormal behavior such as network traffic, has disappeared after restoring all systems and data
- Monitoring network and systems closely for signs of reinfection.
- Upgrading and updating outdated software and systems.
6. Lessons Learned
After the incident, conduct a post-incident review to assess:
- What worked well during the response?
- What gaps or weaknesses were identified?
- How can the plan be improved for future incidents?
- The costs and lead time of the incident
- Which documentation needs to be updated based on lessons learned
- Report to authorities and cybersecurity agencies if you haven’t done it earlier.
How to Create an Incident Response Plan in 5 Steps
1. Assemble an Incident Response Team (IRT)
Your IRT should include representatives from IT, security, legal, operations, and public relations. Define clear roles, such as:
- Team Leader: Oversees the entire response process with designated responsibility and authority.
- Team Members: Include experts, at least two from the different teams (IT, security, legal, operations and public relations).
- Forensic Analyst: Investigates the cause and scope of the incident. Provides guidance for containment.
- Communications Lead: Manages internal and external communication.
2. Conduct a Risk Assessment
Identify potential threats and vulnerabilities unique to your organization. Focus on:
- Critical systems and data assets.
- Gaps in your current security measures.
- Risks associated with third-party vendors or remote work setups.
3. Develop Incident Response Procedures
Outline actionable steps for common scenarios. Incident response procedures should include:
- Prioritization of systems and data
- Evaluation of incident
- Steps to isolate and remove threats (clean rooms and malware detection)
- Steps for data recovery, system restoration, and business continuity.
- Documentation of lessons learned and review of response effectiveness.
4. Plan for Communication and Training
Every IRP should establish clear communication strategy from leaders to communication channels. It should include:
- Internal communication protocol to update stakeholders and employees.
- External communication protocol to prepare public statements and notifications to customers and/or partners.
- Training awareness to educate employees on incident response procedures
5. Test and Update the Plan
Schedule regular reviews and testing, including:
- Conduct simulated incidents, drills, or tabletop exercises to validate IRP.
- Conduct penetration testing to validate defenses and required updates to IRP
- Update the plan quarterly, annually, or as needed
- Review and ensure adherence to relevant laws, regulations, and industry standards.
- Refine procedures, update training, and address gaps.
- Update the IRP regularly to account for new threats, technologies, and regulatory changes.
Common Pitfalls in Incident Response Planning
- Lack of Coordination: Misalignment between cybersecurity and IT backup teams can lead to delays and confusion.
- Insufficient Training: Unprepared staff may escalate the incident by mishandling the response or making public comments.
- Bad Backups: Restoring from untested or compromised backups that can reinfect production environments again.
- Lack of Backups: By either losing access to backups as part of the attack or not keeping off-line backups.
- Overconfidence in Ransom Payments: Paying a ransom doesn’t guarantee data recovery. Even if you receive decryption keys, the decryption could fail. According to the latest Veeam Ransomware Trends Report, 27% of organizations that paid never regained access.
- Not having expert assistance: Consider having third-party vendors such as Include suppliers, contractors, and expert partners in the IRP.
