FGAs meaning is defined as fine-grained authorization, which offers precise and flexible access control by considering multiple factors such as who a user is, what they're trying to do, and even when and where they're doing it. This approach ensures that users get just the right access they need — nothing more. FGA combines attributes and policies to determine whether a user should have access to a specific resource, providing enhanced security, improved flexibility, and better compliance with regulatory requirements. It has real-world applications in healthcare records management, financial services, e-commerce platforms, and educational institutions, where granular control allows for super-specific permissions, reducing vulnerabilities and ensuring that users only access what they need.
