CheckPoint 156-590 Exam - Topic 1 Question 3 Discussion

The correct answer is D. Inactive. A protection set to Inactive is not enforced for matching traffic, so it does not impose the same inspection and enforcement cost as active protection states. Check Point documentation explains that a Threat Prevention profile determines which protections are activated and which Software Blades are enabled for a rule or policy. The protections a profile activates depend on factors such as performance impact, threat severity, confidence level, and blade-specific settings. Check Point best-practice material also describes that administrators may tune IPS profiles and set protections to prevent, detect, or inactive.

The relative resource logic is direct: Prevent is usually the most expensive because the gateway must inspect and enforce a blocking action inline. Inspect and Detect still require traffic analysis and matching logic, even if the final result is logging rather than prevention. Inactive removes the protection from enforcement consideration, making it the lowest resource option. This does not mean administrators should disable protections indiscriminately; Inactive should be used only when justified by risk, false-positive analysis, performance tuning, or compensating controls.
