Why is network segmentation important for large organizations?

• A. It encourages collaboration between departments
• B. It increases complexity of network management
• C. It reduces overall visibility
• D. It helps in controlling access to sensitive areas

Answer: (D)

Network segmentation is an essential strategy for large organizations primarily because it helps in controlling access to sensitive areas. By dividing a larger network into smaller, manageable segments, organizations can implement specific security measures and access controls tailored to the needs of each segment. This means that sensitive data can be isolated and protected from less secure or public-facing areas of the network. Moreover, segmentation minimizes the potential attack surface by limiting lateral movement within the network. If a security breach occurs in one segment, the impacts can be contained, reducing the risk of widespread damage. Additionally, it facilitates compliance with regulatory requirements by ensuring that only authorized personnel can access sensitive information. In organizations where collaboration is crucial, proper segmentation can also retain the necessary access among departments while still protecting sensitive data, without encouraging unnecessary exposure or potential breaches. Thus, controlling access through network segmentation is a fundamental practice for maintaining security in large and complex network environments.
