Figure 3: The three most common risk-related concepts are security, reliability, and safety

Source: Emerging Technology Observatory AGORA. Note that the security and reliability risk concepts have subcategories. If a document is tagged with a subcategory, it is also tagged with the corresponding category (in this case, security or reliability risk concepts); however, subcategories are not exhaustive of the categories. Furthermore, subcategories and categories are not mutually exclusive – a document can be tagged with multiple categories and subcategories, including multiple subcategories for a given category.
