Incident response is a structured approach to managing the aftermath of a security breach or cyberattack, known as an IT incident. The aim is to minimize damage and reduce recovery time and costs. This process is ideally carried out by the organization’s Computer Security Incident Response Team (CSIRT), which includes members from information security, general IT staff, and C-suite executives. The team may also involve individuals from legal, human resources, and public relations departments. Incident response follows the organization’s Incident Response Plan (IRP), a set of written instructions outlining the response to network events, security incidents, and confirmed breaches. It’s a proactive, business-wide function that ensures quick decision-making with reliable information, involving not only technical staff but also representatives from various core aspects of the business.
