Intrusion detection and security monitoring are mature disciplines on enterprise IT networks but provide limited visibility into operations/OT control systems networks.
The biggest barriers to universal monitoring and detection coverage for operations networks are the serious security risks of connecting operations networks to enterprise networks, the Internet or cloud infrastructures. Such connections though, are essential to central security monitoring and OT intrusion detection systems (IDS).
This situation is changing – a new gold standard for universal monitoring of operations networks has emerged, based on experience at many kinds of industrial sites. Unidirectional gateway technology is enabling IT connectivity, cloud connectivity and network traffic monitoring without risk, and the technology enables safe and convenient placement and management of OT IDS sensors as well.
