Why is segmentation of a VPC network important?

Segmentation of a VPC network plays a crucial role in managing security policies effectively. By dividing a virtual private cloud (VPC) into subnets or segments, organizations can isolate different workloads, applications, or environments. This isolation helps in applying tailored security policies that address specific security requirements without affecting other segments. For example, sensitive data can be placed in a separate subnet with stricter access controls, while less sensitive applications can reside in a different segment with more relaxed policies.

This targeted approach to security ensures that the attack surface is minimized and that security measures can be appropriately scaled according to the needs of various applications. Additionally, segmentation can improve overall network performance and management by allowing teams to focus on specific areas within the VPC, making it easier to monitor and respond to potential threats.

The other choices do not capture the essence of segmentation effectively. Establishing internet connectivity does not inherently require segmentation; and while segmentation might simplify some firewall configurations, it doesn’t eliminate the need for them entirely. Moreover, increasing physical space for resources does not pertain to the logical structuring and security benefits afforded by segmentation.
