In previous posts, we have reviewed the main types of attacks at the channel level. It is worth noting that today there are many tools for dealing with threats at the channel level. For example, almost all modern switches have the means to control MAC addresses, prevent overflows, and other means. In addition, attacks at this level are widely known, and even if you use equipment not from Cisco, you can easily find the appropriate instructions for configuring protection.
As for the attacks described in previous posts, it is worth noting that for their successful implementation, an attacker needs to have physical access to a local network. In other words, a hacker must first remotely hack into a machine located on a local network (for example, using the methods described later in my next posts), and then try to implement the described attacks from this computer. Or the attacker is one of the company's employees who has access to the local network. This should be kept in mind when preparing a network protection plan.
Well, in the following posts we will move on to the network level.
