Network Defense Essentials (NDE) Practice Exam

Which of the following statements about decentralized authorization is correct?

1. It only allows admin users to grant access.

2. It does not maintain separate databases for resources.

3. Users can provide access permissions to others.

4. It is the most secure type of authorization.

The correct answer is: Users can provide access permissions to others.

Decentralized authorization allows users to manage and grant access permissions to others, which enhances flexibility and promotes peer-to-peer interactions. This approach empowers individuals within a system to control access to their resources without relying solely on a centralized authority. It is particularly beneficial in environments where collaboration is key, as it enables users to directly share access to files, tools, or services based on trust and need, rather than through a bureaucratic process managed by admin users. In contrast, centralized authorization typically restricts the ability to grant permissions to administrators only, which can slow down processes and limit flexibility. The notion that decentralized authorization does not maintain separate databases for resources is inaccurate; rather, it can involve multiple databases, often depending on the specific implementation. While decentralized systems can offer certain security advantages, stating that it is categorically the most secure type of authorization overlooks variables such as implementation quality and the specific security measures in place. Understanding these dynamics highlights why allowing users to grant access permissions to others embodies a fundamental characteristic of decentralized authorization.
