Coarse-grained access control is simpler and broader, offering general permissions to wide sections of an application but potentially limiting flexibility. Fine-grained access control provides detailed, context-sensitive permissions for individual users, enhancing security at the cost of complexity. The choice between these two types depends on factors such as scalability, compliance, and security requirements. Coarse-grained is suitable when access needs are uniform and do not require fine distinctions, while fine-grained is ideal for complex applications with strict regulatory requirements. A hybrid model combining both coarse-grained and fine-grained control can also be used.
