Incident response (sometimes called cybersecurity incident response) refers to an organization’s processes and technologies for detecting and responding to cyberthreats, security breaches or cyberattacks. The goal of incident response is to prevent cyberattacks before they happen, and to minimize the cost and business disruption resulting from any cyberattacks that occur.
A security incident, or security event, is any digital or physical breach that threatens the confidentiality, integrity or availability or an organization’s information systems or sensitive data. Security incidents can range from intentional cyberattacks by hackers or unauthorized users, to unintentional violations of security policy by legitimate authorized users.
As noted above, an organization’s incident response efforts are guided by an incident response plan. Typically these are created and executed by a computer security incident response team (CSIRT) made up of stakeholders from across the organization—the chief information security officer (CISO), security operations center (SOC) and IT staff, but also representatives from executive leadership, legal, human resources, regulatory compliance and risk management.
