What process involves analyzing an incident and determining steps to prevent future occurrences?

The process of analyzing an incident and determining steps to prevent future occurrences is known as "lessons learned." This involves a thorough review of the incident to understand what went wrong, how it happened, and what measures can be implemented to avoid similar issues in the future. By reflecting on the experience gained from the incident, organizations can improve their security posture, update policies or procedures, and enhance training for employees. This proactive approach is essential for continuous improvement in incident management and overall security practices.

The other options focus on different aspects of managing security incidents. "Prevention" refers more to the measures taken to avoid incidents before they occur, while "incident response" is the immediate actions taken to handle a security breach when it happens. "Remediation" deals with the steps taken to correct vulnerabilities or damage after an incident has occurred. While these processes are all important, the specific focus on reflecting and learning from what has occurred aligns with the definition of "lessons learned."
