This section contains technical documentation I have created and decided to share with the community. I plan to continue to expand this section with certification study notes, how-to guides, and other useful information.


What is is a side project maintained by me (Richard Davis). You can find macOS and iOS software created by 13Cubed, random code snippets written in Bash, C, Perl, and Python, Cisco-related information, and other various geeky things I’ve decided to share.

What is your background?

I received my first computer in 1984 at age seven and never looked back. I started a computer company (service, networking, consulting, and training) in 1996 shortly after I graduated from high school, and sold it 10 years later in 2006. I then spent nine years at a state college in Georgia. While there, I served as Network Support Specialist, Information Security Officer (ISO), and later Chief Information Security Officer (CISO). I am currently employed by a large organization in the aerospace industry, where I lead the information security program and have the privilege of working with an incredibly talented group of security professionals with expertise in digital forensics, pen testing, and incident response. I've worked in Information Technology for 21 years, nine of which specifically in Information Security. I have a Bachelor of Science in Cybersecurity and hold 22 industry certifications, including CISSP, CCNP R&S, CCNP Security, GCFA, GCFE, and CEH.
