A cloud services firm wants to install a new appliance that inspects incoming flows prior to reaching protected hosts. The design team seeks real-time analysis with low load on internal servers. How should the new appliance be placed and set up to satisfy these goals while ensuring logs are accurately recorded?
Run it in a central zone; pass flows to the protected hosts for full analysis afterwards
Setup the appliance near the core hosts with minimal scanning and rely on external gateways to filter incoming connections
Position it at the edge in a bridging setup, then forward its logs to a dedicated monitoring server on a separate subnet
Place it behind the main defensive barrier and have it block traffic after it enters the protected network
Placing the unit at the perimeter in transparent mode allows suspicious patterns to be analyzed before passing into sensitive zones. Sending logs to a collector on a quarantined network segment preserves performance and provides separation for monitoring data. Locating the appliance behind the primary firewall fails to intercept threats before they enter. Routing flows unfiltered in a middle tier misses the chance to stop malicious activity. Setting it inside the core with only limited checks puts more burden on internal firewalls for detection.
