This plan provides clear guidelines for responding to a variety of potential scenarios, including data breaches, distributed denial-of-service (DDoS) attacks, firewall breaches, malware outbreaks, insider threats, data loss and other security breaches.
What is an Incident Response Plan?
An incident response plan lays out the definitions of various incidents, escalation requirements, personnel responsibilities, key steps to follow and the people to contact in the event of an incident. It serves as a roadmap to help organisations quickly and effectively mitigate the impact of a security breach, minimise downtime and restore normal business operations.
- All staff should be trained to understand their role in maintaining the security of the organisation.
- It is recommended to review the incident response plan quarterly for effectiveness.
- Preparation of press responses in advance is advised to deal with potential media inquiries during a cybersecurity incident.
- Developing a plan to identify roles in the event of an incident is crucial.
- Conducting a tabletop exercise to simulate a cybersecurity incident response is beneficial.
- After an incident, holding a retrospective meeting to analyse the incident and suggest areas for improvement is essential.
- Based on the retrospective meeting findings, updating policies and procedures is necessary for future incidents.
- Communicating the incident findings to staff helps in building trust and fostering a culture of security.
By having a well-defined incident response plan, organisations can minimise the damage, restore operations quickly and protect their reputation in the event of a security breach.
Importance of Having an Incident Response Plan
In today’s digital landscape, where cyber threats are becoming more frequent and sophisticated, having an effective incident response plan is crucial for businesses of all sizes. An incident response plan outlines the recommended actions and procedures needed to recognise, respond to, and recover from a security incident, minimising the impact on operations, finances, and reputation.
According to Deloitte’s 2016 Privacy Index, 59% of customers are unlikely to do business with a company that has experienced a data breach. Implementing an IR Plan offers five significant benefits in minimizing the impact of cyberattacks and strengthening an organisation’s defences against cyber threats:
- Faster Incident Response: A well-defined incident response plan can reduce the time it takes to identify, contain, and mitigate the effects of a security incident, minimising operational disruptions and financial losses.
- Early Threat Mitigation: Proactive monitoring for suspicious activity and having a plan in place can significantly reduce the time it takes to identify and respond to a security incident, preventing it from escalating into a more severe breach.
- Disaster Recovery Plan Launch Prevention: An effective incident response plan can help organisations avoid the need to activate a full-scale disaster recovery plan, which can be costly and time-consuming.
- Better Business Continuity: By outlining the steps to be taken during and after a security incident, an incident response plan can help organisations maintain business operations and minimise the impact on customers and stakeholders.
- Improved Communication and Action: A well-documented incident response plan establishes clear communication protocols and assigns specific roles and responsibilities to the incident response team, enabling a coordinated and effective response.
Furthermore, in industries subject to strict data protection and cybersecurity regulations, having a well-documented incident response plan in place can aid in demonstrating commitment to compliance and avoiding potential penalties.
By investing time in creating a detailed incident response plan outlining specific steps to follow in the event of a security incident, businesses can reduce response time, streamline processes, and better manage risk exposure. Effective incident response planning is crucial in today’s digital landscape where cyber threats are becoming more frequent and sophisticated.
Key Benefits of an Effective Plan
Crafting a comprehensive incident response plan can yield substantial benefits for businesses of all sizes. By proactively preparing for potential security incidents, organisations can enhance their overall resilience and mitigate the adverse effects of cyber threats.
Faster Incident Response
Data analysis has shown that businesses with an effective incident response plan can reduce the overall impact of an incident by 76%. Organisations that conduct regular incident response plan training for employees demonstrate a 45% faster response time to security breaches.
Early Threat Mitigation
An incident response plan enables businesses to spot early signs of an incident or attack, allowing them to contain the situation and recover more efficiently. Companies that update their incident response plans at least once a year are 67% more likely to effectively mitigate risks.
Disaster Recovery Plan Launch Prevention
By implementing a robust incident response plan, organisations can often prevent the need to launch complex and costly disaster recovery measures. In fact, 92% of businesses that experienced a cyber incident without a proper response plan in place faced extended downtime.
Better Business Continuity
A well-crafted incident response plan helps to ensure business continuity by minimising the impact of security incidents. Studies have shown that organisations with well-documented incident response plans are 50% less likely to experience data breaches.

Compliance regulations such as GDPR, PCI DSS, and HIPAA often require organisations to have a comprehensive incident response plan in place. By meeting these regulatory requirements, businesses can avoid costly fines and reputational damage.
Investing in a well-crafted incident response plan can yield significant benefits for organisations, from faster incident response and early threat mitigation to improved business continuity and regulatory compliance. By prioritising incident preparedness, businesses can enhance their overall security posture and build trust with customers, partners, and stakeholders.
Incident Response Steps and Frameworks
Effective incident response is crucial for organisations to mitigate the impact of cyber threats. Several incident response frameworks have been developed by industry thought leaders, each providing a structured approach to handling security incidents. Two of the most prominent frameworks are the NIST “Computer Security Incident Handling Guide” and the SANS Institute’s “Incident Management 101” guide.
The NIST framework outlines a four-step incident response cycle:
- Preparation
- Detection and Analysis
- Containment, Eradication, and Recovery
- Post-Incident Activity
The SANS framework, on the other hand, suggests a six-step process:
- Preparation
- Identification
- Containment
- Eradication
- Recovery
- Lessons Learned
While the wording and grouping of the steps may differ, the fundamental incident responsestepsare largely similar across these frameworks.
Adopting a proven incident response framework, such as NIST or SANS, can provide organisations with a comprehensive and structured approach to handling security incidents. By following these established incident response steps, organisations can enhance their preparedness, improve their ability to detect and respond to threats, and minimise the potential impact of cyber incidents.
“Effective incident response is essential for organisations to safeguard their digital assets and maintain operational resilience in the face of cyber threats.”
Irrespective of the specific framework chosen, the key is to ensure that the incident response plan is tailored to the organisation’s unique needs, regularly tested, and continuously updated to address evolving threats and best practices.
Creating an Incident Response Plan
Developing an effective incident response plan is crucial for businesses to manage and mitigate the impact of security incidents. This process involves two key steps: creating an incident remediation policy and forming an incident response team.
Develop an Incident Remediation Policy
The first step in creating an incident response plan is to develop or update an incident remediation and response policy. This policy serves as the foundation for all incident handling activities, providing incident responders with the authority needed to make crucial decisions. It outlines the organisation’s approach to incident management, including procedures for incident detection, analysis, containment, eradication, and recovery.
Form an Incident Response Team
The next step is to form an incident response team, which is responsible for maintaining the incident response plan. This team should include technical staff with platform and application expertise, as well as infrastructure and networking experts, systems administrators, security experts, and representatives from customer-facing, legal, and public relations teams. By assembling a diverse group of professionals, organisations can ensure a comprehensive and effective response to security incidents.
Effective incident response planning is essential for businesses to mitigate the impact of security breaches and maintain business continuity. By developing an incident remediation policy and assembling a dedicated incident response team, organisations can be better prepared to respond to and recover from security incidents quickly and efficiently.
“Regular drills and simulation exercises are recommended for testing incident response plans, ensuring preparedness in the event of an incident.”
Develop Playbooks
Incident response playbooks are the foundation of a mature incident response team. While every security incident differs, most types of incidents follow standard patterns of activity and would benefit from standardised incident response procedures. Organisations should develop a series of playbooks that address their most common incident types, enabling the incident response team to refer to pre-defined procedures rather than figuring out what steps to take every time an incident occurs.
Incident response playbooks can significantly improve the speed and effectiveness of an organisation’s incident response. They provide a single, authoritative, and up-to-date source of instructions for all personnel involved in incident response, ensuring consistent incident response activities, quicker responses, and the resumption of normal operations faster.
The National Institute of Standards and Technology (NIST) provides broad groupings of incidents based on common attack vectors, which can be used to define specific handling procedures for incident response playbooks. These playbooks are also valuable for training new staff, conducting incident response exercises, and tests.

Incident response playbooks are a key component of incident management for DevOps, IT Operations, and cybersecurity teams. By following standardised incident response procedures, organisations can improvise and adapt their response to changing situations while maintaining a structured approach to incident resolution.
“Effective incident response playbooks need to be simple for teams to follow in stressful situations. Following a predetermined incident response process allows for improvisation and adaptation in changing situations.”
Conducting postmortems after each incident is vital for understanding contributing causes and enacting preventative actions. Collaboration and communication are key components for effective incident resolution, with face-to-face meetings, postmortem approvals, and designated priority actions being effective methods of post-incident analysis and resolution.
Incident Response Communication Plan
Effective incident response efforts require significant communication among different groups within an organisation, as well as with external stakeholders. An incident response communication plan should address how these groups work together during an active incident and the types of information that should be shared with internal and external responders. The plan must also address the involvement of law enforcement and outline who in the organisation is authorised to call in law enforcement and when it is appropriate to do so.
Developing a robust incident response communication plan is crucial for every business to manage and mitigate potential crises. By utilising DevOps practices, organisations can streamline communication, collaboration, and resolution activities during security incidents.
Communication channels such as email, instant messaging, and incident response platforms can facilitate the quick dissemination of information. Additionally, defining incident severity levels (low, moderate, high, or critical) allows for prioritising incidents based on their impact and ensuring timely responses.
Clear roles and responsibilities ensure that everyone knows their tasks during an incident. Identifying key stakeholders and their preferred communication channels is critical for effective incident response communication planning.

An effective incident response communication strategy involves clear messaging, timely updates, and transparent external communication. By maintaining clear and concise communication, organisations can enhance stakeholder understanding and trust during critical situations.
Regular training of stakeholders to understand their responsibilities and communicate effectively during incidents is crucial. Additionally, conducting mock incident drills can aid in evaluating the effectiveness of the communication plan and identifying areas for improvement.
Continuous improvement, driven by feedback mechanisms, is essential to ensure the incident response communication plan remains up-to-date and addresses evolving threats and communication needs.
Test and Update the Plan Regularly
Maintaining an effective incident response plan requires regular testing and updates. Organisations should not wait for an actual crisis to find out if their plan works as intended. Instead, they should proactively run simulations and drills to ensure the processes outlined in the plan are functional and relevant.
Regularly testing the incident response plan is crucial for several reasons:
- It helps identify gaps in security defences or operational processes that need to be addressed.
- It optimises response time, coordination, and communication, leading to quicker and more effective responses to incidents.
- It empowers organisations to mitigate potential risks proactively, reducing the likelihood of future incidents.
- It ensures the plan remains up-to-date and relevant as the security landscape evolves.
According to the National Cyber Security Centre (NCSC), a basic incident response process should include key elements such as contact information, escalation criteria, a flowchart, and guidance on legal and regulatory requirements. Organisations should test and update these elements regularly to maintain preparedness and effectiveness.
Tabletop exercises and simulations are recommended for effectively testing incident response plans through realistic scenarios. These exercises help identify areas for improvement and ensure the plan can be executed efficiently during an actual incident.
| Incident Response Plan Test Frequency | Benefits |
|---|---|
| Quarterly or Semi-annual |
|
By updating the incident response plan regularly and testing it through simulations, organisations can ensure they are ready to handle security incidents effectively, minimise downtime, and protect their assets, reputation, and customers.
