**Definition:** Common terms describing uncertainty and potential loss that drive consistent risk discussions.
## Key Facts
- Asset: item of value (data, systems, reputation).
- Threat: potential cause of an unwanted incident.
- Vulnerability: weakness exploitable by threats.
- Likelihood vs. Impact: chance vs. magnitude.
- Exposure Factor (EF), SLE, ARO, ALE for quantification.
- Inherent vs. Residual risk distinctions.
- **Verify:** check official (ISC)² CBK and current exam outline.
>[!tip] **Exam Relevance**
- Interpreting risk statements and calculations
- Mapping controls to reduce likelihood vs. impact
>[!note] **Mnemonic**
- “A Threat Values L/I.”
### Example
Q: If inherent risk is high but residual is low, what worked?
A: Effective controls.
## Revision Checklist
- [ ] Define threat vs. vulnerability
- [ ] Calculate SLE and ALE
- [ ] Differentiate inherent vs. residual
- [ ] Assign risk vs. control ownership
