Nick Leghorn presents on risk analysis for IT professionals. He discusses key concepts like defining risk, scope, probability calculations, and the risk equation. Methods for analyzing risk include simple and probabilistic charts, and annualized loss expectancy. Factor-based models can provide quick assessments using scales to evaluate factors like criticality, accessibility, and effects. Cost-benefit analysis should be used to evaluate options and their impacts on future risk. The goal is to understand potential threats and losses in order to cost-effectively mitigate risks.
