Needs access to relevant traffic
Rule tuning and throughput planning take expertise
Suricata is a useful option for security teams inspecting traffic on networks they manage. Begin in passive monitoring mode with a selected traffic source and inspect the resulting events before enabling prevention. Start with a small, representative task so you can check the results before extending the setup.
Tune rules to the network's services and capacity, and measure packet loss so blind spots do not remain hidden. Consider the practical trade-off: needs access to relevant traffic.
