   A natural gas pipeline company is implementing a security monitoring solution. The SCADA system uses a mix of legacy serial and modern Ethernet-based protocols. The security team wants to deploy an intrusion detection system (IDS) to monitor both types of traffic. The system must not interfere with operations. What is the most appropriate deployment strategy?

   • AUse passive network taps and SPAN ports to monitor traffic without inline placement
   • BReplace all serial links with Ethernet to enable IDS monitoring
   • CDeploy the IDS inline on the Ethernet segments only
   • DInstall the IDS on the HMI workstations to monitor operator activity

   A power generation plant is implementing a new safety instrumented system (SIS) to protect against overpressure. The SIS is independent of the basic process control system (BPCS). The plant's management wants to connect the SIS to the plant's network for remote monitoring. The safety engineer objects. What is the most important reason for the safety engineer's objection?

   • AThe SIS is not designed to communicate with other systems
   • BConnecting the SIS to the network could expose it to cyber threats that could compromise its safety functions
   • CRemote monitoring would require too much bandwidth
   • DThe SIS would conflict with the BPCS
