Logical separation in a system is achieved through what means?

Logical separation in a system refers to the method of keeping different sets of data or processes distinct from one another without necessarily requiring physical barriers. This is typically achieved through software configurations that control how data flows, ensuring that sensitive information is accessible only to authorized entities while preventing unauthorized sharing or interaction.

By using software-based solutions, such as firewalls, access controls, or virtual networks, logical separation can be effectively implemented without needing to physically disconnect assets or completely isolate systems. This approach allows for flexibility and scalability, which are vital in modern information technology environments. Users can still share resources in a controlled manner while ensuring that data integrity and confidentiality are maintained.

In contrast, physical disconnection or complete isolation typically does not allow for the same level of resource sharing and efficiency as logical separation. Removing all network access could hinder operational capabilities without addressing the core needs for maintaining data security. Thus, logical separation through software configuration is the most effective means in scenarios where maintaining access while securing data is crucial.
