Safe OT Network Intrusion Detection ebook

Safe OT Network Intrusion Detection eBook

Operational Technology Intrusion Detection Systems (OT IDS) add value by raising alerts for suspicious patterns of network traffic, but these systems also impair security when deployed incorrectly. This is because all OT IDS sensor appliances have at least two network ports: one port is connected to a mirror or SPAN port on a managed OT switch, and another is a conventional management port for remote access and for reporting alerts to a Security Information and Event Management (SIEM) system.
