Your mission
- Pick controls for this system within the budget of 7 cost points.
- Submit the design. Until it passes you see only the remaining risk, how many attacks are still too likely, and the weakest point.
- Bring every attack to 10% or less. Then the full breakdown and notes on every control you chose unlock.
Scoring: Each submission counts as an attempt: passing on the first try earns 100 points on the main leaderboard, 10 fewer for each extra submission (never below 10). The Best designs board ranks your best design: the share of risk removed (up to 1000), minus 20 per cost point.
Likelihoods are a teaching model, not measurements: they encode common judgement about how much each control helps.
