[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.

Wait, are we sure about high bandwidth networks? That seems off.

Low processing threshold seems like it could be a component, but I’m not confident about that one.

I practiced a question similar to this, and I think weak network stack sounds like something that could be excluded.

I'm not entirely sure, but I feel like legacy systems could be part of an ICS/SCADA setup, so that might not be it either.

I think I remember that high bandwidth networks are actually a key component, so maybe that's not the answer?

I think the key here is to focus on the core functionality and design of ICS/SCADA devices. High processing power and robust network stacks are usually more important than high bandwidth.

I'm a bit confused on this one. Legacy systems could be a component, but I'm not sure if that's the correct answer. I'll need to review my notes to be sure.

I feel confident that high bandwidth networks are not a component of an ICS/SCADA device. Those systems tend to have more limited bandwidth requirements.

Okay, let's see. I'm pretty sure low processing threshold and weak network stack are not typical components, but I'm not 100% sure about the other options.

Okay, let me see. I know control indicators are related to the audit process, so I'm guessing it has to do with one of the audit stages. I'll eliminate the ones that don't seem relevant.

Okay, let me see here. Service custodian, schema custodian, and policy custodian all sound like they could be common SOA roles. But I'm not sure about "silo custodian" - that one seems a bit unusual.

This seems straightforward enough. I'll carefully analyze the options and select the one that best matches the XML schema to the WSDL elements.

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?

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.
