What is the primary characteristic of explicit authorization in resource requests?

The primary characteristic of explicit authorization in resource requests is that it involves maintaining separate authorization details for each resource request. This approach ensures that permissions are clearly defined and tailored to specific resources or actions. Explicit authorization typically requires that users present their credentials or meet certain criteria before being granted access, which enhances security by allowing precise control over who has access to what.

Maintaining individual authorization details means that every request is evaluated based on its own merits, reducing the chance of unnecessary permissions being granted. This granular approach allows organizations to adhere to the principle of least privilege, ensuring users only have access to the resources necessary for their roles.

In contrast, other options describe characteristics that do not align with the nature of explicit authorization. For example, automatic approval of requests does not align with the need for verification and specific permission checks in explicit authorization. Similarly, the statement about requiring less storage space is not relevant, as the focus of explicit authorization is on the granularity of access control rather than the efficiency of storage. Lastly, the ability to be overridden by implicit techniques does not pertain to explicit authorization's defined structure, as explicit authorization stands independently in its requirement for separate and clear permission management.
