Essential Guide to Building an Incident Response Team Effectively
Building an Incident Response Team: How to Build Your Business's Critical Incident Response Team (CIRT)
Responding effectively to critical incidents is essential for organizations of all sizes. A dedicated Critical Incident Response Team (CIRT) can differentiate between a minor disruption and a major crisis, from cyber attacks to natural disasters — and then get to work minimizing the damage. Unlike a CIRT, a computer emergency response team focuses specifically on cybersecurity incidents, providing specialized expertise in handling and mitigating cyber threats.
The threats facing a modern organization are more varied and far-reaching than a few years ago. Creating a team to respond to the most severe incidents is necessary to help businesses avoid devastating attacks or disasters.
One study found that while 65% of businesses have a plan in place for DDoS attacks, only 29% are prepared for advanced persistent attacks. Businesses must prepare, and developing a CIRT is a valuable way to contain the worst scenarios.
So, we’ll be breaking down how to build a robust and efficient CIRT for your business, ensuring that you are well-prepared to handle any incident that comes your way.
Understanding the Role of a Critical Incident Response Team
A cybersecurity incident response team (CIRT) is a type of critical incident response team that manages and mitigates the impact of unexpected incidents that threaten the stability and security of a business, focusing only on severe incidents. The primary goal of a CIRT is to minimize the impact of an incident on the business and its customers, ensuring a swift and effective recovery.
This specialized team is responsible for detecting incidents, coordinating responses, restoring normal operations, and maintaining clear communication with stakeholders throughout the incident.
Additionally, the role of the CIRT extends beyond immediate incident response. These teams are also involved with planning and preparedness, ensuring that the business is ready to prevent incidents as much as possible and respond rapidly and effectively when they occur.
7 Steps to Developing Your Critical Incident Response Team
Developing a critical incident response team is essential for any organization to effectively respond to security incidents. Here are 7 steps to help you develop your critical incident response team:
Define the Team’s Purpose and Scope: Clearly define the team’s purpose, scope, and responsibilities. Identify the types of incidents the team will respond to and the goals of the team.
Identify Team Members: Identify the team members who will be responsible for responding to incidents. Ensure that the team has a diverse set of skills and expertise, including technical, legal, and communication skills.
Develop an Incident Response Plan: Develop a comprehensive incident response plan that outlines the procedures for responding to incidents. The plan should include procedures for containment, eradication, recovery, and post-incident activities.
Provide Training and Resources: Provide the team with the necessary training and resources to respond to incidents effectively. This includes training on incident response procedures, as well as access to specialized tools and technologies.
Establish Communication Protocols: Establish clear communication protocols for the team, including procedures for communicating with internal stakeholders, external stakeholders, and the media.
Conduct Regular Exercises and Drills: Conduct regular exercises and drills to test the team’s response to incidents. This will help identify areas for improvement and ensure that the team is prepared to respond to incidents effectively.
Review and Update the Plan: Regularly review and update the incident response plan to ensure that it remains effective and relevant. This includes reviewing the plan after each incident to identify areas for improvement.
7 Develop Strategies for Critical Threats
Does your organization have a CIRT ready to take on the most severe threats facing your organization? If so, are they operating as effectively as possible?
Let’s explore how you can develop and refine your critical incident response team to protect your organization against potentially devastating scenarios better. Effective incident response efforts require coordinated actions, including documentation, communication with stakeholders, and the formation of specialized response teams.
1. Defining the Team's Structure and Roles
The first step in building your CIRT is defining its structure and specific roles. Each member has specific responsibilities, ensuring that all aspects of incident response are handled efficiently and effectively.
Incident response manager: The leader who coordinates the response effort, makes critical decisions, and serves as the main point of contact. The response manager must have a strong understanding of incident management’s technical and business aspects.
Technical specialists: IT experts with different areas of expertise should form the majority of the team, such as experts in cybersecurity, infrastructure, and data integrity. These roles are crucial in identifying the incident’s cause, containing and eradicating the threat, and recovering.
Legal advisor: The legal advisor plays a crucial non-technical role in ensuring that the response complies with legal and regulatory requirements and provides guidance on legal implications. The legal advisor also helps handle potential liabilities and ensure the company’s actions are defensible.
Business continuity planner: This specialist focuses on maintaining essential business functions and coordinating with other departments to minimize operational disruption. This role involves working closely with the incident response manager to keep critical business operations operational during an incident or prioritize their recovery.
2. Recruiting and Training Incident Response Team Members
Selecting the right individuals for your CIRT is crucial. Look for employees with expertise in their respective areas who can work effectively with a team and have a proven ability to work under pressure. You may conduct interviews to make sure you choose the right people who are up for the task.
Once you’ve chosen the team members, start planning comprehensive training that covers existing incident response protocols, specific technical skills, communication strategies, and regulatory compliance. It is essential to include legal and PR teams in your incident response team to address regulatory and compliance obligations, ensuring comprehensive communication and legal oversight throughout the incident handling process.
Training should be ongoing with regular updates to inform team members about new threats and response techniques. Simulations and drills ensure the team can effectively handle real-world incidents.
3. Developing and Documenting a Cybersecurity Incident Response Plan
A critical component of your CIRT’s effectiveness is having a well-documented cybersecurity incident response plan. This plan should outline step-by-step procedures for specific scenarios, including cybersecurity threats, natural disasters, and internal failures.
Each plan should provide clear instructions on initial response actions, escalation procedures, and recovery steps. These response plans should be detailed and specific, covering all possible scenarios that the business might face.
Regularly review and update these plans to address new threats and incorporate lessons learned from previous incidents. Involving all relevant departments in the planning process ensures the plans are comprehensive and practical.
4. Establishing Detection and Monitoring Systems
Rapid and effective response to a cybersecurity incident begins with early detection. Implement robust detection and monitoring systems that identify potential threats before they escalate and cause unchecked damage.
The right systems will vary based on your needs, and most involve intrusion detection systems, automated alerts, and regular audits of security measures. These systems provide the CIRT with the necessary warning and data to respond to the scenario.
5. Creating a Communication Plan
Clear and effective communication is vital during a crisis, and incident response planning is essential to ensure a well-designed plan is in place. Organizations need a communication plan outlining how information will be shared with various stakeholders and how team members can collaborate if communication channels are compromised.
The communication plan should be flexible enough to adapt to different incidents so that teams and stakeholders can stay on top of the incident. An external-facing communication plan also ensures you can respond quickly to misinformation or rumours, protecting your reputation.
6. Conducting Regular Drills and Simulations
Conduct regular drills and simulations to gauge and improve your team’s preparedness and effectiveness. Exercises should mimic potential critical incidents your business might face, like data breaches or natural disasters. Regular practice keeps the team ready for a real-world incident and helps identify any gaps in preparedness.
Simulations should be realistic and involve all relevant departments and systems. They should be done in virtual environments. Practice sessions should also include post-incident reviews to identify lessons learned and areas for improvement. This process is crucial for reducing the likelihood of similar issues in future incidents. Regularly testing and refining your response plans ensures that your CIRT is always prepared to handle a real incident.
7. Reviewing and Improving Continuously
Continuous improvement is crucial for maintaining an effective critical incident response team, especially in managing cybersecurity incidents. This ongoing process calls for a thorough review after each incident or drill to understand what worked well and what needs improvement.
Collect feedback from team members and stakeholders to understand their perspectives. From there, update response plans, training programs, and communication strategies as necessary for better results in the next incident. Continuous improvement ensures that your CIRT evolves with the changing threat landscape and becomes more effective.
