See also Granular
TLDR: Granularity refers to the level of detail or specificity in data, systems, or processes. The term, originating in the field of database management and later adopted widely in computing during the late 1980s, plays a significant role in areas like access controls, logging, and data management. Higher granularity means more detailed control or analysis, while lower granularity represents broader groupings or summaries.

In security, granularity is critical for implementing precise policies, such as defining specific roles in role-based access control (RBAC) or tailoring logging levels to capture high-risk actions only. For example, a granular logging system might record changes to sensitive configurations without tracking routine system queries, balancing performance with oversight. Emphasizing granularity enables organizations to align with frameworks like ISO 27001 and achieve better control over resources and operations.
