Which log file should be reviewed when refining web server protection rules?

When refining web server protection rules, the reverseproxy.log is the most relevant log file to review. This log specifically records details about the requests and responses that pass through the reverse proxy, which is essential for understanding traffic patterns, detecting potential threats, and analyzing how the web server is being accessed.

By examining the reverseproxy.log, administrators can gain insights into how effectively their protections are working, identify unauthorized access attempts, and assess the behavior of legitimate users. This information is crucial when fine-tuning security policies, as it directly reflects the interaction between external users and the internal web server.

While the other log files serve important functions—such as access.log recording general access events, firewall.log capturing firewall-related activities, and system.log documenting system events—they do not specifically focus on the aspects of web server protection that are crucial when analyzing and modifying reverse proxy rules. Therefore, the reverseproxy.log is the best choice for this specific task.
