Epidemiologists use various metrics to measure the spread of diseases, and similar metrics can be adapted for phishing emails:
1. Incidence Rate: The number of new phishing emails received within a specific time period. 2. Prevalence: The total number of phishing emails present in an inbox at a given time. 3. Basic Reproduction Number (R0): The average number of new phishing emails generated by one infected account. 4. Attack Rate: The proportion of individuals who fall victim to phishing emails out of those who receive them.
