[All ICS-SCADA Questions]

Which of the following are NOT components of an ICS/SCADA network device?

ALow processing threshold

BLegacy systems

CHigh bandwidth networks

DWeak network stack

Show Suggested Answer

Suggested Answer: C

Industrial Control Systems (ICS) and SCADA networks typically operate in environments where the available bandwidth is limited. They are often characterized by:

Low processing threshold: ICS/SCADA devices generally have limited processing capabilities due to their specialized and often legacy nature.

Legacy systems: Many ICS/SCADA systems include older technology that might not support newer security protocols or high-speed data transfer.

Weak network stack: These systems may have incomplete or less robust network stacks that can be susceptible to specific types of network attacks.

High bandwidth networks are not typical of ICS/SCADA environments, as these systems do not usually require or support high-speed data transmission due to their operational requirements and the older technology often used in such environments.

D) Weak network stack, all the way. You want your ICS/SCADA devices to be about as secure as a cardboard box. What could go wrong?

I'm going to have to go with C) High bandwidth networks. That's just asking for trouble in an ICS/SCADA setup. Gotta keep those data lines nice and skinny.

A) Low processing threshold is definitely not a component of an ICS/SCADA network device.

B) Legacy systems, definitely. Those old-school industrial controllers are probably still running on floppy disks and MS-DOS. Time to upgrade, folks!

A) Low processing threshold? Hmm, isn't that a bit of a oxymoron for an ICS/SCADA device? I'd expect them to have beefy processors to crunch all that sensor data.

I'm going with D) Weak network stack. ICS/SCADA devices need robust networking to handle all that industrial data, right?

C) High bandwidth networks seems like the odd one out here. I mean, who wouldn't want a high-speed network for their ICS/SCADA system? Gotta get that data flowing!
