In today's interconnected digital landscape, the threat of cyber incidents looms large over organisations of all sizes. From data breaches to malware attacks, the potential for disruption and damage is significant. 

To effectively mitigate these risks, organisations must adopt a proactive approach to incident response. This is where an incident response checklist becomes indispensable. Let’s delve into what an incident response checklist entails, why it’s crucial, and the key steps and components involved.

What is an incident response checklist?

An incident response checklist is a predefined set of steps and actions designed to guide an organisation through the process of responding to and managing a security incident effectively. It’s a structured approach to handling security breaches, cyber threats, or any unauthorised access that could compromise information security. 

Essentially, it outlines the necessary protocols and procedures that enable an organisation to detect, respond to, and recover from security incidents swiftly and efficiently.

Incident Response Checklist: Why Response is Crucial

Why is an incident response checklist important?

The importance of an incident response checklist cannot be overstated in today’s digital age. 

Here are several reasons why organisations should prioritise having a well-defined incident response checklist:

Timely response

A checklist provides a structured approach to incident handling, ensuring that incidents are addressed promptly.

Comprehensive coverage

It helps determine the scope and nature of the incident, ensuring that no aspect is overlooked.


By streamlining incident response efforts, organisations can minimise downtime and mitigate potential damage more effectively.


It ensures that all incidents are handled according to a standardised process, regardless of the type or severity.

Learning and improvement

The checklist facilitates a review of response actions after an incident, enabling organisations to learn from incidents and improve their incident-handling capabilities in the future.


Many regulatory frameworks, such as NIST (National Institute of Standards and Technology), mandate having an incident response plan in place, making a checklist essential for compliance.

Risk mitigation

It helps in identifying and addressing indicators of compromise early, thereby reducing the overall impact of security breaches.

Importance of incident response checklists

Steps in an incident response checklist

While the specifics may vary depending on the organisation and its unique needs, a typical incident response checklist generally includes the following key steps:

  • Preparation and planning: This involves developing an incident response plan and identifying the incident response team with clearly defined roles and responsibilities.
  • Containment: Isolating affected systems or networks to prevent further damage or unauthorised access.
  • Eradication: Removing the cause of the incident, such as malware or unauthorised access points, from affected systems.
  • Post-incident activities: Conducting a post-incident review, documenting lessons learned, and updating the incident response plan and checklist accordingly.
  • Continuous improvement: Implementing measures to enhance incident response capabilities based on insights gained from the incident.
Handling an Event of an Incident with a Checklist

Key components of an incident response checklist

A well-crafted incident response checklist typically includes the following essential components:

  • Contact information: List of key contacts within the incident response team, including external stakeholders, if necessary.
  • Roles and responsibilities: Clearly defined roles for team members involved in incident response, specifying their tasks and authorities.
  • Incident response procedures: Detailed procedures for each stage in the incident response process, from detection to resolution.
  • Communication protocols: Guidelines for internal and external communication during and after an incident, ensuring timely and accurate information sharing.
  • Tools and resources: List of tools, software, and resources necessary for incident detection, analysis, containment, and recovery.
  • Documentation requirements: Templates for documenting incident details, actions taken, and outcomes for compliance and future reference.
  • Training and awareness: Plans for training staff on incident response procedures and raising awareness about the importance of cybersecurity.
How a Checklist Helps in Incident Response

Implementing an incident response checklist

To implement an incident response checklist effectively, organisations should consider the following best practices:

Tailor to unique needs

Customise the checklist to fit the unique operational and security needs of the organisation.

Regular testing and review

Regular drills and simulations should be conducted to test the effectiveness of the checklist and identify areas for improvement.

Integration with other plans

Ensure alignment with other organisational plans, such as business continuity and disaster recovery plans, for comprehensive incident management.

Legal and regulatory compliance

Stay updated with legal and regulatory requirements related to incident response and ensure the checklist meets those standards.

Feedback loop

Establish a feedback loop to gather input from incident responders and stakeholders to continuously enhance the checklist.

Streamlining Incident Handling with a Checklist

Top 8 incident response plan templates: Streamlining cyber incident response

In the event of a security incident, organisations must be prepared with a robust incident response plan to mitigate risks effectively. A well-designed incident response plan template serves as a foundational tool, providing structured guidance for incident handling and ensuring minimal disruption to business operations. 

Here's a look at eight exemplary incident response plan templates that guide organisations through the complexities of cyber incident response.

1. NIST incident response plan template

The National Institute of Standards and Technology (NIST) offers a comprehensive incident response plan template. It outlines a systematic approach to incident handling, covering preparation, detection, analysis, containment, eradication, recovery, and post-incident activities. 

This template is widely recognised for its thoroughness and adherence to best practices in cybersecurity.

2. SANS incident response template

The SANS Institute provides a practical incident response template emphasising a proactive approach to cybersecurity incidents. It includes detailed sections on incident detection methods, response strategies, and recovery procedures. 

The SANS template is known for its clarity and actionable steps tailored to various incidents.

3. ISO 27001 incident response plan template

This template, aligned with the ISO 27001 standard for information security management, focuses on integrating incident response into an organisation’s overall security framework. 

It emphasises continuous improvement and compliance with international standards, making it ideal for organisations seeking rigorous incident management protocols.

4. CIS incident response plan template

The Center for Internet Security (CIS) offers a straightforward incident response plan template that is easy to implement and adapt. It covers essential components such as incident detection, containment, recovery, and post-incident analysis. 

The CIS template is known for its practicality and suitability for organisations of varying sizes and industries.

5. NCCIC incident handling checklist

The National Cybersecurity and Communications Integration Center (NCCIC) provides a detailed incident handling checklist. While not a full template, it complements existing incident response plans by offering a checklist format for quick reference during incident response. 

It includes steps for initial response, analysis, containment, eradication, recovery, and lessons learned.

6. ITIL incident response plan template

Based on ITIL (Information Technology Infrastructure Library) principles, this incident response plan template focuses on aligning incident management with IT service management best practices. 

It emphasises service restoration and minimising impact on business operations, making it suitable for IT-centric organisations.

7. DHS cyber incident response plan template

The Department of Homeland Security (DHS) provides a comprehensive cyber incident response plan template tailored for critical infrastructure sectors. It includes guidelines for incident detection, response coordination, communication protocols, and regulatory reporting. 

The DHS template is essential for organisations operating in sectors with heightened cybersecurity risks.
