Question

If you had to add a layer to the OSI model, what layer would you add and why?

Answer 1

Solution:

If I had to add a layer to the OSI Model, I would add one layer before the presentation layer where I would be able to encrypt and decrypt the raw data coming in a stream in cases of both request and response. In the presentation layer, we know that the raw data comes which transforms into a presentable form, I'll add one more layer which will encrypt and decrypt that raw data also to enhance security. There might be many questions about this but this is my point of view.

Application layer

Presentation layer

The layer which I'll add

Session Layer

Transport Layer

Network Layer

Data Link Layer

Physical Layer
