I’m thinking I’ll probably end up going down the networking route when it comes to InfoSec so I figured it would be a good idea to pick a protocol and do a deep dive on it. Something simple. Something I can become an ‘expert’ in relatively easily. Small scope. Focus. Depth, rather than the massively overwhelming breadth that InfoSec is on first encounter. So I started looking at ARP traffic on my little home network in Wireshark. And I found mystery almost instantly.
