Jeff McJunkin is the founder of Rogue Valley Information Security, a consulting firm specializing in penetration testing and red team engagements. Jeff found the offensive side of cyber security very alluring during one the first penetration tests of his career. Feeling the challenge of host defenses like AV and centralized logging, and, at the time, knowing nothing about AV evasion or avoiding events that are likely to cause alerts, it was all very exciting. The challenge of successfully accomplishing the goal of that pen test, using essentially only native tools, was addictive for Jeff. He was hooked. Since those first penetration tests, Jeff has gone on to become an expert in the field, doing assessments for Fortune 100 companies, architecting two major versions of Core NetWars Experience, and contributing a vast amount of material to SANS Penetration Testing.
Jeff is an awesome instructor and explains very complex topics in an easy to understand manner! Thank you for this great course!
Jeff is insanely clever, funny, and totally at home in front and leading a class. I would gravitate to courses led by Jeff without a second thought.
Willingness to provide in world examples to the methodology as well as provide multiple ways for the student to learn (Lecture, Labs, Show, Do). As this was my first SANS course, I'm grateful that he was the instructor.

In 2026, as information security professionals, you’re facing your own steam-powered saw: Artificial Intelligence. AI is reshaping cybersecurity faster than Paul could clear a forest, and some of you might feel like you’re swinging your axe against an unstoppable machine.
Building your own home lab is a great way to keep up with the ever-changing IT world. Well, how does one actually go about building a home lab? That's the part that gets more complicated. Do you really need a whole rack full of off-lease servers and some enterprise-grade switches? No! New-ish high-end servers and workstations are surprisingly powerful, capable of mocking up a pretty complicated network, including attacker systems and even incorporating wireless communications. In this talk, Jeff will walk through both the hardware and software stacks he uses and recommends, including a number of ways to incorporate Microsoft software without paying exorbitant licensing fees. Jeff will also outline several lab designs that can be used for a number of scenarios, including defense, offense, and forensics.
