What is an incident response team?
An incident response team is a specialized security unit within an organization whose primary duties involve responding to cyber incidents and addressing compromised systems, applications, and data.
While automated cybersecurity tools are essential for dealing with cyber attacks, incident response teams are an irreplaceable component of enterprise cybersecurity. Without strong incident response teams, businesses can’t effectively bounce back from cyber attacks, especially those that target critical systems. Incident response helps reduce downtime and outages resulting from cyber threats and help address root causes to prevent problematic incidents from recurring in the future.

Incident response frameworks, like NIST CSF and CIS Controls, break down the incident response process differently. And each enterprise’s incident response process depends on numerous factors, including existing IT and cloud infrastructure, business goals, budgets, and sector-specific intricacies. However, the fundamental duties of an incident response team remain the same: When cyber incidents occur, they must identify the root cause, analyze the damage, fix the resulting issues, and take proactive measures to prevent similar security incidents in the future.
Why are incident response teams so important? According to a report published in 2023, 66% of those surveyed claimed that cybersecurity has become more difficult, and 27% claimed that it has become extremely difficult—with the majority of respondents pointing to the increase in cyberattacks as a primary factor. As cybersecurity demands grow at alarming rates, it’s of paramount importance for enterprises to optimize their incident response teams.

What are the common roles on an incident response team?
For comprehensive incident management, businesses need a unified and well-balanced incident response team, rich with technical expertise and technical skills. Incident response teams primarily comprise IT professionals, but it’s also important to have representation from human resources, compliance, and legal teams.
Senior members of incident response teams typically focus on coordination and collaboration with key internal stakeholders. They also manage the overarching strategy and execution of the incident response lifecycle. On-the-ground team members focus on more technical incident response activities.
That said, businesses can delegate incident response roles and responsibilities based on their resources and needs. Some roles and responsibilities can be split between multiple individuals, and others may demand the sole focus of a single individual.

What are the different kinds of incident response teams?
There are primarily three different kinds of incident response teams: internal, external, and hybrid. Each incident response team model offers unique advantages and trade-offs, and what works for one business may be detrimental to another.
Here’s what each model entails and why a business might choose it:
Internal incident response teams
An internal incident response team comprises in-house IT and cybersecurity professionals. It could also include representatives from other departments in the company. In an internal model, incident response teams rely on existing infrastructure, tools, capabilities, and expertise to detect and resolve cyber incidents.
Internal incident response team models can result in faster response times because team members are already well-acquainted with the company’s IT ecosystem. However, internal teams may struggle to mitigate incidents that demand highly specialized skills or knowledge. Another factor to consider is that internal incident response teams may approach their tasks with inherent biases and perspective limitations.
External incident response teams
An external incident response team is made up of outsourced IT and cybersecurity professionals. In this model, businesses use the services of a third-party provider to respond to cyber incidents.
External incident response teams provide many unique benefits, including rich and diverse cybersecurity knowledge, vast cross-industry experience, easier scalability, and a more objective approach to complex cyber challenges. However, external incident response teams may lack knowledge of an organization’s goals and tech stack. Depending on the scale and needs of an enterprise, this model can also be quite expensive.
Hybrid incident response teams
A hybrid incident response team features both internal and external team members. In this model, businesses may assign certain incident response roles and responsibilities to in-house employees, and outsource others to third parties.
With a hybrid incident response team, businesses can potentially unlock the best of both worlds. A hybrid incident response approach can leverage the domain-specific knowledge of in-house professionals and address knowledge and skills gaps with the help of external experts. With powerful leadership and meticulous execution, hybrid incident response teams can be an effective and affordable solution for many enterprises.
Best practices for building an incident response team
The following are some important best practices and recommendations that businesses should consider when forming an incident response team.
1. Start building your team before the incident
It’s critical that incident response teams are ready to respond before an incident occurs. If your team is internal, make sure that all team members are clear on roles and responsibilities. If you are engaging external experts, consider a retainer structure so that the external team is familiar with your environment and ready to respond ahead of time. This is particularly important in cloud environments, where critical data can be lost if teams do not move extremely quickly when an incident is first detected.
2. Evaluate existing IT and cybersecurity capabilities
When building an incident response team, businesses must have a clear picture of what IT and cybersecurity capabilities already exist within their ranks. To do so, enterprises should conduct a thorough cybersecurity skills and capabilities assessment to uncover existing incident response strengths and weaknesses.
3. Define critical roles and responsibilities
It’s crucial that all critical roles and responsibilities (discussed above) are staffed and integrated into incident response teams. Businesses must clearly define and differentiate the scope and objectives of each of these roles. If particular in-house skills are lacking, it’s a good idea to consider augmenting with a third-party cybersecurity expert.
4. Ensure around-the-clock availability
Considering the volume and velocity of cyber attacks today, companies can’t afford to have incident response teams with nine-to-five schedules. To ensure 24/7 availability, businesses may have to be creative with how they structure their incident response teams. For example, they may choose onsite staff for a traditional nine-to-five shift and online or off-site team members for the remaining hours.
5. Nurture a positive and healthy security culture
To establish a robust incident response team, it’s essential to create a vibrant cybersecurity culture that replaces blame with respect and accountability. Furthermore, no one can expect overworked cybersecurity professionals to keep their perimeters safe. That’s why it’s best practice to make sure that roles and responsibilities are proportionately and fairly distributed amongst team members and that job satisfaction and morale are healthy at all times.
6. Focus on cloud skills and capabilities
There’s a major cybersecurity skills shortage across the world, and cloud security, in particular, is a critical and glaring deficiency. Since most enterprises embrace cloud-based infrastructures and services, cloud skills and knowledge must be a core requirement of incident response team members rather than an afterthought or secondary skill.
7. Identify the right tools for incident response teams
The best way to create strong incident response teams is by equipping team members with cutting-edge cybersecurity tools. For example, by providing forensics teams and incident responders with end-to-end cloud forensics tools, runtime sensors, and a robust cloud detection and response (CDR) platform, businesses can significantly boost their cybersecurity potency.
