OWASP’s new Subtractive Security Top 10 argues that deleting a risky path is more effective than merely detecting when someone uses it. 🧩 Like clearing an overgrown backyard instead of installing more cameras Imagine a backyard with overgrown bushes hiding the fence line, a side gate that never locks, and a shed door that won’t quite close.
