The CompTIA SY0-401 Security+ exam takes a more lecture-based approach when compared to the A+ or Network+ certifications. You must understand security devices and protocols, as well as the processes and procedures used when working in network security. This requires a study approach that emphasizes the myriad definitions and processes that you’ll find on the Security+ exam.

I’ve built this huge 40-page guide by compiling the text, charts, pictures and tables from my videos. The amount of information in these Course Notes is massive!

Here’s a sample of what you’ll find:

The Security+ certification doesn’t require that you know as many port numbers as other exams, but there’s still a big list. I’ve built a table with everything you’ll need to know.
