Can S/MIME, XML and IPsec operate in one protocol layer?
As a part of the IPv4 enhancement, IPsec is a layer 3 OSI model or internet layer end-to-end security scheme. In contrast, while some other Internet security systems in widespread use operate above layer 3, such as Transport Layer Security (TLS) that operates at the Transport Layer and Secure Shell (SSH) that operates at the Application layer The link layer corresponds to the OSI data link layer and may include similar functions as the physical layer, as well as some protocols of the OSI's network layer. These comparisons are based on the original seven-layer protocol model as defined in ISO 7498, rather than refinements in the internal organization of the network layer. In module 7, it said IPSec can connect two segments using layer 2 protocols. (and in one of the question of practice test, there is a question that refers to 'linking layer-2 network segments'). I think it should need more explanation on how it could be done using ' layer 2 protocols'. Jun 21, 2019 · Which OSI layer does IPsec operate at? A . Network B . transport C . Application D . Presentation. View Answer. Answer: A Explanation: A major difference between IPsec and other protocols such as TLS is that IPsec operates at the Internet network layer rather than the application layer, allowing for complete end-to-end encryption of all communications and traffic.

Can S/MIME, XML and IPsec operate in one protocol layer? Each of these operates at a different layer of the OSI model: S/MIME runs at the application layer, IPsec runs at the network layer and XML is a presentation layer protocol.

Sometimes it can be hard to understand the difference between IPsec and protocols like TLS/SSL. After all, they both just provide security, right? They do, but they do it in different ways and at different levels. One of the best ways to compare IPsec and TLS/SSL is to look at them in the context of the OSI model.
