Actual exam question for ISC2's SSCP exam
Question #: 40
Topic #: 3
[All SSCP Questions]

At which OSI/ISO layer is an encrypted authentication between a client software package and a firewall performed?

Show Suggested Answer Hide Answer
Suggested Answer: C

Encrypted authentication is a firewall feature that allows users on an external network to authenticate themselves to prove that they are authorized to access resources on the internal network. Encrypted authentication is convenient because it happens at the transport layer between a client software and a firewall, allowing all normal application software to run without hindrance.

This question feels familiar; I think we practiced one that mentioned the Transport layer for secure connections.

I remember something about the Session layer being involved in establishing connections, but I can't recall if that's where encryption happens.

I think the encrypted authentication happens at the Transport layer, but I'm not entirely sure.

I’m leaning towards the Network layer, but I feel like that might be wrong. Encryption seems more related to the Transport layer, right?

This looks straightforward, I'd go with option A and create the segment directly from the selection.

I feel like I practiced a question similar to this, and the answer was about the Official Endpoint layer. Could it be that?

This is a good opportunity to demonstrate my knowledge of JumpCloud and how user management impacts different systems. I feel confident I can nail this question.
