We're breaking ground with this episode, folks! For the first time in 7MS history, we've got a guest on the show (finally, right?!).

Rob Sell is an IT manager who has been working in IT for many years, with a focus on information security specifically for the last 4 years. He recently came home from Defcon 25 with a third place in the SE CTF.

Rob sat down with me to discuss the CTF, how to make an outstanding CTF audition video, OSINT tools/tips/techniques, the value of tech/security certifications, career advice and much more!

Interview notes and links

• Here's Rob's Defcon CTF audition video:

• EchoSec helps you see a geographical area at a certain point in time. According to the Web site, EchoSec is "the most comprehensive social sentiment tool on the market" - hmmmm, seems like a great SE tool!

• X-Ray is "a tool for recon, mapping and OSINT gathering from public networks."

• Michael Bazzell's Web site has online training, free tools and other goodies. Michael also has some books.

• Christopher Hadnagy has a podcast that's strictly focused on SE. He's also got some books.

• ArcGIS isn't necessarily labeled as an SE tool, but can certainly be used for SE efforts.
