What is an incident response team (IRT)?

An incident response team (IRT) is a dedicated group that is primarily responsible for preparing for, detecting, responding to, and recovering from cybersecurity incidents. The role of the IRT includes developing response plans, conducting drills and training, and assessing potential security risks to ensure the organization can effectively manage incidents when they occur.

This team plays a crucial role in ensuring that an organization can quickly respond to breaches or other security threats, minimizing damage and restoring normal operations. Their preparation involves creating strategies and protocols for identifying and handling security events, making option B the most accurate representation of what an incident response team does.

Other choices do not align with the primary focus and responsibilities of an IRT. The maintenance of systems, marketing for security products, or software development does not pertain to incident management and response, which focuses specifically on handling and mitigating cybersecurity events.
