Greetings! I’m Corey Thuen. I spent a number of years at Idaho National Laboratory, Digital Bond, and IOActive (where we affectionately refer to ourselves as pirates, hence the sticker). At these places, my job was to find 0-day vulnerabilities on the offensive side of things.

Now, I am a founder of Gravwell, a data analytics platform for security logs, machine, and network data. It’s my background in offensive security that informs my new life on the defensive side of the house. I believe that defense involves more than looking for how threat actor XYZ operates, it requires an understanding of the environment and maximizing the primary advantage that defense has—this is your turf and no one knows it like you do. One of my favorite quotes about security comes from Dr. Eugene Spafford at Purdue (affectionately known in the cybersecurity community as “Spaf”) who said, “A system is good if it does what it’s supposed to do, and secure if it doesn’t do anything else.” We help our customers use data to make their systems good and secure, but for this post let’s talk bad guys, 0-days, and hiding in the noise.
