Which report is essential for documenting security incidents?

An incident report is essential for documenting security incidents because it provides a detailed account of what occurred during the incident, including the time, location, individuals involved, and any actions taken in response to the situation. This report serves several important purposes: it ensures that accurate information is preserved for future reference, facilitates communication among security personnel and management, and can be used as evidence if legal or disciplinary actions are needed.

Incident reports are typically structured to include specific fields that allow for clear and organized documentation, making it easier to analyze patterns or trends in security issues over time. In contrast, other options like a daily log serve more general record-keeping functions, while billing reports focus on financial aspects, and performance reviews evaluate employee effectiveness. None of these alternatives provide the specific and comprehensive documentation needed for security incidents like an incident report does.
