Continuous IoT/OT threat monitoring, incident response, and threat intelligence

IoT/OT threat intelligence and behavioral analysis are used to keep an eye out for unusual or unauthorized behavior. By immediately identifying unwanted remote access and rogue or compromised devices, you may improve IoT/OT zero-trust security. You can view traffic history, look up real-time alerts, and scan for risks quickly. You can also identify current dangers such as zero-day malware and survival techniques that static signs of compromise fail to pick up on. For more analysis, look into full-fidelity packet captures (PCAPs).

For a given device profile, normal behavior is determined by establishing communication flows as baselines and understanding the systems it communicates with. With this understanding, policies can be aligned with a zero-trust framework that limits device communications to required systems and nothing else.

Continuous monitoring also helps organizations to be resilient in...
