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

AMemory

BNetwork

CHost

DAnomaly

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.

Ah, the age-old question: which IPS can handle encrypted data? It's like trying to find a needle in a haystack... or a backdoor in a secure encryption algorithm!

I bet the answer is C) Host. That's the one that monitors the actual system, so it would be able to see what's happening with the encrypted data, right?

I'm not sure, but I think D) Anomaly might also be able to monitor and validate encrypted data by detecting unusual patterns or behavior.

I see your point, but I still believe it's C) Host. It makes more sense to me that the host would be able to monitor the encrypted data on the system itself.

I think it's actually B) Network. It can monitor and validate encrypted data as it passes through the network.

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!

Anomaly IPS sounds interesting, maybe it does have some decryption capabilities.

I'm leaning towards Host IPS, it can inspect encrypted data on the endpoint.

I think it might be Network IPS, since it can monitor traffic in real-time.

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?

Anomaly IPS is specifically designed to detect unusual behavior, so it could be useful for identifying encrypted data threats.

True, but Memory IPS focuses on monitoring memory usage and can also detect anomalies in encrypted data.

But Network IPS can also inspect network traffic for any suspicious activity, including encrypted data.

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.
