OSS security debate: security through obscurity vs thriving in max entropy

fkasummer · x · 2026-11-05

A debate on open-source security. @venki argues 'end of OSS / security through obscurity' has merit: attackers get white-box access to find and deeply verify vulnerabilities, and one discovered bug can be reused against many targets — while an equivalent bug in closed-source compression code reachable only via HTTP is far harder to find.

fkasummer counters: you want to thrive in max entropy, not defend an arbitrary bound against adversaries' intelligent entropy pump — identify the equilibrium maximizing collective leverage (knowledge in OSS); the other direction is fatal.
