What characteristic defines decentralized authorization systems?

Decentralized authorization systems are characterized by having each resource manage its own user permissions independently. This means that instead of relying on a single, centralized database that governs access to all resources, each resource maintains its own separate database or system for defining who can access it and under what conditions. This allows for greater flexibility and can enhance security because access can be tailored to the specific needs and characteristics of each resource.

In decentralized systems, permissions can be managed at a more granular level and can reflect unique requirements or policies specific to each resource. This also minimizes the risk associated with a single point of failure that would be present in a centralized system, where compromising the central database could potentially expose all resources at once.
