Network Security and Traffic Analysis – As vendor default settings are seldom adequate for any particular environment, and network configurations change from time to time (such as during network expansion or the implementation of new services), periodic network security review can avail much in eliminating hard-to-spot gaps. Critical Intelligence can review your control system network security posture, comparing network traffic to actual perimeter device configurations (such as firewall rules, IDS rules and router ACLs), consider application requirements, identify gaps, and recommend mitigations in accordance with industry best-practice.
