Resource isolation methods in network security can achieve which of the following goals?

Resource isolation methods in network security are designed to control and manage how resources are allocated and used within a system or network. The correct choice emphasizes the importance of limiting resource usage and ensuring fairness among different users or processes accessing those resources.

By isolating resources, particularly in environments where multiple users or applications share the same physical infrastructure (like in cloud computing or multi-tenant systems), organizations can set boundaries on how much resource (such as CPU, memory, or bandwidth) each user or application can consume. This helps prevent any single user or process from monopolizing resources, which could lead to performance degradation or service denial for others. Additionally, fairness in resource allocation can help maintain quality of service and ensure that all users have the necessary resources to perform their tasks effectively, adhering to pre-defined usage policies.

This approach is fundamental in ensuring that the security and performance of the network are maintained while providing a level playing field for all users involved.
