Definition
An incident is an event that violates or threatens an organization's security policies, acceptable use policies, or standard security practices. It represents a compromise of confidentiality, integrity, or availability of information or systems. In practice, incident response involves detecting, analyzing, containing, eradicating, and recovering from security breaches. Understanding incidents is crucial for minimizing damage, reducing recovery time and costs, and preventing future occurrences. For example, a phishing attack that successfully compromises user credentials constitutes an incident. This differs from a vulnerability, which is a weakness that could lead to an incident. Incident concepts are fundamental to cybersecurity certifications like CompTIA Security+, CySA+, and CISSP.
