Which type of Control Model is used in Check Point Access Control Firewall Policy?

The correct answer is A. Check Point Access Control Firewall Policy is based on a Positive Control Model, also known as a whitelist model. The administrator explicitly allows approved traffic, and traffic that does not match allowed rules is dropped by cleanup behavior. This is the correct firewall posture because it minimizes attack surface and avoids allowing unknown traffic by default. Option B and D describe blacklist/negative-control behavior, where specific unwanted traffic is blocked while everything else may be allowed. That model is more commonly associated with controls such as Application Control, URL Filtering, or threat-category blocking. Option C incorrectly uses “Permissive” with whitelist terminology; whitelist is restrictive because only approved traffic is allowed. In Access Control firewall policy, the proper pattern is: define required access, place specific rules above general rules, and end with an explicit cleanup rule to drop unmatched traffic.
