I recently re-read The Cuckoo's Egg by Cliff Stoll.
The failures described in the book during 1980s don't feel historical.
It feels like we’re still struggling with the same security fundamentals we struggled with decades ago.
Back then, attackers succeeded because:
- Environments weren't fully understood
- Logs were generated but rarely reviewed
- Old accounts lingered unnoticed
- Trust replaced verification
Fast forward to today. Different tools. Same outcomes.
We now have automation everywhere. Yet automation still depends on knowing what exists, what's normal, and what should no longer be there.
That's the part we assume is handled. But is it?
What struck me most this time wasn't how limited the tools were back then. It was how deliberate the observation had to be.
Visibility came before tooling, because it had to. Today, tooling often comes first, and visibility is assumed to follow.
We've built sophisticated defenses, but somewhere along the way, we stopped asking basic questions.
The fundamentals didn't change. We just got better at believing they were already taken care of.
Thanks for the great conversation Ryan Donovan.
