Background for this topic.
An incident is a suspected or confirmed event that threatens the confidentiality, integrity, or availability of information or systems, or violates a security policy. Examples include unauthorized access, malware execution, exposed credentials, data loss, and disruptive attacks. Not every alert is an incident: triage determines whether an event is credible, its scope, and the assets or data involved.
Incident handling requires timely detection, analysis, containment, eradication, and recovery. Practitioners must preserve relevant evidence, identify affected accounts and systems, assess whether data was accessed or altered, and prevent recurrence. Clear escalation and documentation support privacy or regulatory notifications when applicable. Findings should feed security improvements such as closing exploited vulnerabilities, strengthening access controls, and updating detection and response procedures.
