Building an effective incident response team (IRT) is a fundamental step in preparing an organization to manage and mitigate information security incidents swiftly and efficiently.
The team should consist of professionals with diverse skills and clear roles, enabling coordinated actions across detection, analysis, containment, eradication, recovery, and communication.
Defining these roles clearly ensures that responsibilities are understood, resources are well allocated, and incident handling aligns with organizational objectives.
