One of the things that really helps me learn something is taking notes while I read the book or watch videos. Here I present to you my notes that I have typed up for reviewing later. I find it useful to write my notes by hand and then type them in later. This method gives me a chance to read them at least 2-3 times before I put them away.

Some of my guides are shorter than others. It just depends on the technology and how much information I felt I needed to be prepared. Sorry there are many images, I don’t have the time to create nice network diagrams.

Also everything is published in PDF format. You’ve been warned.

Tech Justin is a blog focusing on Cisco networking, security and other tech stuff that interests a guy named Justin.

I'm a security engineer with my CCNP and CCSP. I've decided to take the plunge and begin working on my CCIE R&S certification. I love technology and all that if can do it. I also believe most end user technology needs to be more secure and protect an individual's privacy by default.
