What mode should the web server protection policy be set to when refining the configuration?

In the context of configuring web server protection policies, opting for Strict Mode is essential when refining the configuration. Strict Mode provides the highest level of security by enforcing stringent rules that help in detecting and mitigating threats effectively. It blocks any suspicious traffic and only allows well-defined and expected requests to access the web server. This mode is particularly beneficial during the configuration phase, as it helps to identify potential vulnerabilities and ensure that only legitimate traffic can access the web server.

This approach forces the administrator to carefully review and set appropriate exceptions, allowing for a secure and tailored configuration that minimizes the risk of attacks. Therefore, using Strict Mode during refinement is crucial for establishing a robust security posture for the web server.

Flexible Mode, Custom Mode, and Allow Mode do not provide the same level of security or guidance during the configuration process, as they may allow more traffic through based on predefined rules or relaxed settings, which can lead to security gaps if not monitored closely.
