Ethan Rahn (er4hn)

This is the personal website of Ethan Rahn.

I am a software engineer, specializing in cybersecurity.

  • I deeply enjoy understanding a complex system, decomposing it, and finding where form does not meet intended function 🔍️
  • I am most familiar with securing products (this may be referred to as “blue team” stuff) 🛡️
  • I have an, unfortunate, familiarity with certification standards such as “FIPS 140” and “cPPND” (fka “Common Criteria”) 📝️

I enjoy reading about technology and imagining where it will take the world next.

  • Admittedly, I take a pessimistic worldview on this. I blame my time spent on cybersecurity for this 🤦️
