## Risk Quantification Framework
Every security investment must be justified in business terms. "We need better security" is not a business case. "$800K expected annual loss from this unmitigated risk" is.
### Core Formula
```
ALE = SLE x ARO
ALE = Annual Loss Expectancy (expected cost per year)
SLE = Single Loss Expectancy (cost if the event occurs once)
ARO = Annual Rate of Occurrence (probability of occurrence per year)
```
### Risk Register Template
| Risk ID | Threat | Asset | SLE | ARO | ALE | Mitigation Cost | ROI | Priority |
|---------|--------|-------|-----|-----|-----|-----------------|-----|----------|
| R-001 | Data breach (customer PII) | Customer database | $2.5M | 0.15 | $375K | $120K/yr | 3.1x | Critical |
| R-002 | Ransomware | Production systems | $1.8M | 0.10 | $180K | $80K/
