[All ICS-SCADA Questions]

Which type of Intrusion Prevention System can monitor and validate encrypted data?

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.

Ooh, this is a toughie. I'm gonna guess Anomaly IPS, just because it's the odd one out. Maybe it has some super-secret decryption powers we don't know about!

I feel like Host IPS might be the way to go. It can monitor the system itself, so it could potentially validate the encrypted data before it even reaches the network, right?

I think you're right, Host IPS can definitely monitor the system and validate encrypted data.

I'm leaning towards Network IPS here. Isn't that the one that can inspect the actual data packets? Seems like it would be the best bet for handling encrypted traffic.

Yes, you're right. Network IPS is able to inspect the actual data packets, including encrypted traffic.

Hmm, encrypted data? That's a tricky one. I bet the answer has something to do with SSL or TLS. Gotta love those security protocols!

That makes sense, Host can indeed monitor encrypted data on the local system. Good point!

I disagree, I believe it's Host because it can monitor encrypted data on the local system.
