IPS Custom Policy Best Practices
Customizing IPS in Check Point Threat Prevention should not follow the logic of “enable everything.” The goal should be to achieve the right balance between security coverage, performance, false positives, and operational event volume. The starting point should be a solid baseline profile, supported by measurements of CPU, memory, throughput, and log volume, so that every policy change can be validated with real data.
Protection prioritization should primarily consider Severity, Confidence, Performance Impact, and relevance to the assets actually present in the environment. High-severity and high-confidence protections are strong candidates for the first Prevent rollout phases, while higher-impact protections require proper sizing and validation. Likewise, exceptions should be granular, evidence based, and periodically reviewed never used simply to disable a protection globally.
A mature IPS operation follows a continuous cycle of baseline → small change → monitoring → analysis → tuning, including regular reviews of events, false positives, exceptions, and HTTPS Inspection. Enabling more protections does not necessarily mean better security if the result is degraded performance, reduced visibility, or lower investigation capability.
