Define the term "incident response."

The term "incident response" refers to a structured approach for managing and addressing security breaches or cyber incidents when they occur. This process involves a series of defined steps that aim to effectively manage the situation, minimize the impact, restore normal operations, and prevent future occurrences. By adopting a systematic response, organizations can ensure that they have a clear plan for detection, containment, eradication, recovery, and lessons learned after an incident.

This method is critical in cybersecurity as it helps organizations mitigate damage, ensures compliance with laws and regulations, and enhances their overall security posture. A well-defined incident response plan not only prepares the team to respond to incidents more efficiently but also helps in minimizing downtime and protecting sensitive information during a security event.

The other options refer to different aspects of cybersecurity but do not encapsulate the focused and reactive nature of incident response. Proactive measures and assessments are about preventing incidents before they happen rather than responding to them after.
