Why Networking? And why so practical?

Networking is hands down the most important thing to understand in security, and still, people just kind of fumble through it. One of the reasons this stuff is so hard is because most people just don't spend enough time with it to get an innate knowledge of what is going on, which makes things hard to conceptualize.

The other reason, and I think the main reason, is because all the courses about networking focus on memorizing random things and doing calculations, but don't spend any time looking at packets or generating packets. It's like if you were trying to learn how to be a carpenter by looking at furniture. Stupid.

People waste too much damn time "learning" networking. This course is here to fix that. Build your mental models now, learn what is actually happening, then save the memorization for later. Everything is easier when you understand the context.
