Why is logging essential in Fortinet devices?

Logging is essential in Fortinet devices because it plays a crucial role in monitoring security incidents and conducting compliance audits. Through logging, devices record events, activities, and system changes, which allows administrators to maintain visibility over network operations and security postures. This detailed record of events is invaluable when responding to security breaches or incidents, as it provides the data necessary for forensic analysis to understand what occurred, how it happened, and the impact it had.

Moreover, logging supports compliance auditing by ensuring that organizations meet various regulatory standards that mandate detailed record-keeping of network activities and incidents. When logs are maintained accurately, they can serve as proof of adherence to security policies and regulatory requirements, thus helping organizations avoid potential fines and legal repercussions.

The other choices do not capture the primary purpose of logging. Reducing hardware costs is not a direct benefit of logging; in fact, efficient logging practices may require robust hardware for proper storage and processing. Increasing network speed is also unrelated to logging, as logging can potentially consume bandwidth and processing resources. Finally, while logging might indirectly influence user experience by improving service reliability post-incident, it is not fundamentally designed to enhance user experience directly. Logging is fundamentally about maintaining security oversight and compliance, making it an essential component of network security management
