A manufacturing plant has a flat OT network with no monitoring. The security team wants to implement a monitoring solution that can detect anomalous behavior on the OT network without affecting production. Which approach is most suitable?

Deploy a passive network monitoring solution that analyzes traffic copies

Install host-based agents on all PLCs

Use a manual log review process

Deploy an active intrusion prevention system inline

A manufacturing plant uses a DCS with a redundant control network. A disgruntled employee physically accesses a PLC and connects a laptop to the control network. The security team wants to detect such unauthorized physical access. Which control is most effective?

Install CCTV cameras in the control room

Implement 802.1X port-based authentication on the control network switches

Use IPsec encryption on all control network traffic
