Isaca Cybersecurity-Audit-Certificate Exam - Topic 3 Question 38 Discussion

Posted by Sarah on Mar 23, 2025 at 11:58 PM

At which layer in the open systems interconnection (OSI) model does SSH operate?

Suggested Answer: D

Replicating privileged access to a user's own mobile device presents the greatest risk to corporate data. This is because it potentially allows unauthorized access to sensitive information if the device is lost, stolen, or compromised. Privileged access means having elevated permissions that are typically reserved for administrators. When such access is available on a personal device, it bypasses many of the security controls that a company would normally have in place.

Option A, remote wipe, is actually a security feature that can protect data if a device is lost or stolen. Option B, lack of training, can increase risk but does not directly expose data like privileged access does. Option C, devices not obtained through corporate provisioning, can be a risk, but this risk is generally less than that of replicating privileged access.

I thought it was the Session layer for a second.

Totally agree, it's definitely the Application layer!

SSH operates at the Application layer.

Yeah, it's Application. No doubt about it!

Wait, are you sure it's not the Presentation layer?

I definitely recall SSH being associated with the Application layer from my study notes.

I’m leaning towards the Presentation layer, but I could be mixing it up with another protocol.

I remember practicing a question about SSH and the OSI model, and I think it was related to the Session layer.

I think SSH operates at the Application layer, but I’m not completely sure.

I'm drawing a blank on the OSI layers. Maybe I should just make an educated guess and move on. I'll select D, the network layer, but I'm not very confident about that.

Okay, let me think this through. SSH is used for remote access and secure communication, so it's probably not at the presentation or network layers. I'll guess C, the application layer.

The OSI model can be tricky to remember, but I think SSH is a secure shell protocol, so it must be at the session layer. I'll go with B.

Hmm, I'm a bit unsure about this one. I know SSH is a network protocol, but I can't remember which OSI layer it's associated with.

I'm pretty sure SSH operates at the application layer, so I'll go with C.
LA

I'm feeling a bit session-al today, so I'll go with B. Hopefully, it's not a network outage!

Definitely the Application layer. That's where all the cool, secure protocols like SSH live, right? *winks*

Absolutely! SSH is a secure protocol that operates at the Application layer.

That's right! SSH is indeed a protocol that operates at the Application layer.

Yes, you're correct! SSH operates at the Application layer.

Hmm, I thought SSH was a Session layer protocol. Guess I need to brush up on my OSI model knowledge.

SSH operates at the Application layer of the OSI model, so I'm going with C.

I'm not sure, but I think SSH operates at the Network layer because it deals with network connections.
GI

I agree with Staci, SSH does operate at the Application layer because it provides secure communication between applications.

I think SSH operates at the Application layer.
