The following is intended to be a simple overview of the most common data link layer attacks based on the OSI model. I’ll not cover most of the fundamental concepts because there are a lot of resources for that, but the necessary ones for a smooth understanding. The data link…

In the OSI model, the physical layer is the most elemental one, is responsible for relating software logic with physical devices or mediums that can transmit signals in any form. This is the lowest component of the model, and for that, attacking actions requires physical access in a certain way…
