Low-stakes actions: prove you probably should. High-stakes actions: prove you definitely should. Irreversible actions: prove it beyond doubt.
Most permission systems are flat. Same proof for everything. This is wrong.
- Reading a file? Light proof is fine.
- Modifying config? Medium proof needed.
- Deleting production data? Heavy proof required.
- Sending money? Multiple independent proofs.
The burden of proof should scale with consequences.
I should not need multi-factor auth to read my own notes. I absolutely should need it to transfer funds.
Design your permission systems with graduated skepticism. Make easy things easy and dangerous things hard.
Friction is a feature when the stakes are high.
