I'm a world-wide security evangelist, meaning I write and speak about hackers, cryptography, fraud, malware and all that interesting stuff.

I've spoken at over 30 conferences on all six developed continents. Some of my favorite engagements were speaking at RSA Europe in Amsterdam, InfoSec in London and Gartner Data Center in Las Vegas

I write a bi-weekly column at SecurityWeek, and have had the good fortune to write for DarkReading and SC Magazine and Network World.

They call me the "one-take wonder" in the studio, because I've done so many videos that I just do it in one take anymore.

I'm a fly-fisherman, a baseball fan and a craft beer enthusiast.

Conde Nast's Sexiest Man of the Year

"Everyone, let me introduce you to David Holmes, F5's World-wide Security Evangelist and Conde Nast's Sexiest Man of the Year!"

My friend Jack Fenimore was introducing me to an audience of about 60 people in Cincinnati, Ohio. I thought that was the best introduction ever. Even if that last part wasn't true.

So I was telling that story to another friend of mine, John Wagnon wh...

Threat Modeling the Internet of Things

Here is Part 0 (or part 1) of a series on threat modeling the Internet of Things. Here I introduce these two topics: Internet of Things and Threat modeling and suggest that maybe we need to spend more time putting them together. I like the intro and extro for this piece :)

Five Reasons the CISO is a Cryptocurrency Skeptic

I've been a cryptocurrency skeptic for years. Much of that skepticism comes from hundreds of hours of talking with real CISOs and directors of security about how they can better protect real (not virtual) currency. Even with the resources of enormous budgets and huge security teams they can barely keep the hackers from stealing all the monies. When F5 Labs asked me to write up my opinions about Bitcoin, I threw this together. Not a bad little piece.

Malware Grows, Goes After Data Centers

Maria Korolov interviewed and quoted me extensively for a Data Center Knowledge piece on WannaCry. I had no time to prepare for this interview, and was surprised when it got published. Sometimes I prepare a LOT and nothing comes of it. You never know, I guess. Just keep doing them.

Was DC25 My Last DEF CON?

My writeup of the 25th annual DEF CON, the world's premiere hacker conference in Las Vegas, Nevada. I've been going since DEF CON 7. What has changed? You'd be surprised at what has, and what hasn't.

The Coolest Talk at Defcon 25 That No One is Writing About

Three researchers, two from Bastille Networks, gave a fantastic talk about reverse engineering the Comcast and Time Warner home networks. Really well done! I was surprised no one was writing about it, so here you go!

RSA in a "Pre-Post-Quantum" Computing World

I'd like to take credit for this one, I really would. We had a fascinating email discussion at work and our primary SSL/TLS engineer wrote this great email about the nuances of the asymmetric algorithm, RSA, and how it might be affected by computing advances in the future. I told him it would make a nice little article, and we tried to put his name on it but he didn't want the attention, and he asked me to put my name on it. So we did. Sometimes that happens.
