This lesson focuses on Quantitative Risk Analysis which examines the following:
Probability ARO (Annual rate of occurrence)
Impact EF (exposure factor)
Single Loss Expectancy (SLE) AV*EF= SLE
Annual Loss Expectancy (ALE): SLE*ARO=SLE
Cost of control
This lesson also discusses risk determination which must take into account the following: - Evaluating magnitude of impact
- Evaluating likelihood of threat
It is important to remember that you cannot eliminate all risks. You can reduce and mitigate but elimination just isn't possible.
