Knowledge Check

1. What is the main priority difference between IT and OT security?

IT prioritises availability; OT prioritises confidentiality IT prioritises confidentiality; OT prioritises availability Both have the same priorities OT does not need security

2. Why are many SCADA protocols inherently insecure?

They were designed for speed, not security, in an era of isolated networks They are too new to have been tested They use too much encryption They were designed by hackers

3. What did the TRITON/TRISIS attack target?

A corporate email server A Safety Instrumented System (SIS) at a petrochemical plant A cloud data lake A drilling rig control system

4. What does IEC 62443 Security Level 4 (SL-4) protect against?

Accidental violations Simple intentional attacks Sophisticated attacks with moderate resources Nation-state level threats with extensive resources

5. What is the critical rule during OT incident containment?

Shut down all systems immediately Never disable a Safety Instrumented System (SIS) Disconnect all sensors Notify the media first

6. What is the zones and conduits model in IEC 62443?

A physical building layout standard A method for segmenting OT networks into security zones with controlled communication paths A cable colour-coding scheme A training programme for operators
