Eccouncil Exam ICS-SCADA Topic 3 Question 16 Discussion

Actual exam question for Eccouncil's ICS-SCADA exam
Question #: 16
Topic #: 3
[All ICS-SCADA Questions]

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

Show Suggested Answer Hide 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 the answer isn't 'All of the above'? SCADA networks can be a real hodgepodge of outdated and underpowered tech.

Definitely, legacy systems and weak network stacks are common in SCADA networks.

Haha, I bet the developers of these SCADA systems wish they could use 'A) Low processing threshold' as a feature! Those things need some serious computational power.

B) Legacy systems is a tricky one, but I'm going to go with that. SCADA networks often have to work with older equipment, so that's likely not a component of the network devices.

D) Weak network stack seems like the obvious choice here. SCADA devices need robust networking capabilities, not weak ones.

I think the correct answer is C) High bandwidth networks. Those are usually required for modern SCADA systems, not components of the network devices themselves.
