There are other network security tools that we can use and automate with Python. Let's take a look at a few of them.
Virtual Local Area Networks (VLANs), has been around for a long time. They are essentially a broadcast domain where all hosts can be connected to a single switch, but are petitioned out to different domains, so we can separate the hosts out according to which host can see others via broadcasts. The reality is that most of the time, VLANs are mapped out to IP subnets. For example, in an enterprise building, I would likely have one IP subnet per physical floor,
192.168.1.0/24 for the first floor,
192.168.2.0/24 for the second floor. In this pattern, we use 1 /24 block for each floor. This gives a clear delineation of my physical network as well as my logical network. All hosts wanting to communicate beyond its own subnet will need to traverse through its layer 3 gateway, where I can use an access list to enforce security.
