Eric Thomas, Detection & Response Engineer at HD Supply, brings his 15 years of experience in tech and cyber to the show this week to discuss collaboration— the most essential piece of the purple team formula. Eric walks us through his day-to-day routine as an engineer and provides us with his own unique insight into his current company's purple team process. Additionally, Eric teaches us about his unique approach to training future professionals with red and blue team skills and philosophies.

What is the collaboration between red and blue teams like in your current role as a detection and response engineer?
Although Eric is humble enough to admit that the purple team processes in his current work are not his singular idea, he will admit that he led the charge for a more collaborative environment. Leading this initiative started with the desire for a better SOC team. Eric's collaboration wasn't formal at all— he would simply ask other departments for help with their expertise— but this process led to a massively successful process that continues to this day.
"My idea was, if we're trying to detect adversarial behavior, we have a resource internally. Who are experts at adversarial behavior? Why try to figure this out ourselves, right? It started off as a very informal thing. It started off as [collaborative] teams."
Can you give a brief description of what IoT devices are and what type of testing you do with them?
IoT is more than another acronym in the cyber industry— it refers to the Internet of Things, or the way everyday devices connect to the internet and to each other. The concept of IoT heavily connects to OT, or operational technology. Unfortunately, because these are lesser known systems, they're less secure and less understood by security teams. Eric's team of consultants aims to fix that issue, providing security protocols where there are none.
"We have the technology and the mechanisms to protect our traditional IT. When it comes to OT and Internet of Things (IoT devices), this has been significantly overlooked. What we're seeing is a push to get security professionals more interested in protecting these devices."
How are you training future professionals and teaching them to do things differently from the problematic ways you learned back in the day?
It's almost too easy to slip into the problematic "back in my day" mindset of an experienced professional, but Eric actively combats the idea that the old ways of doing security were better when training students. Instead, Eric advocates for students to take a different, more unified approach to their learning process. Aspiring professionals shouldn't work in a silo and should instead be exposed to red and blue team processes during their learning journey.
"Don’t go into the silo, build your network, talk to people across the aisle, it's gonna make you a better pen tester. That’s what I tell [upcoming professionals], that the more blue team friends you have, it's going to make you a better pen tester.”
