Episode 46 — Network Controls: Segmentation, Firewalls and Microsegmentation

Cloud networks are virtual, but the principles of segmentation remain as important as ever. In this episode, we cover traditional controls such as firewalls alongside modern practices like microsegmentation, which allow for granular isolation between workloads. These techniques reduce the blast radius of an attack and limit lateral movement inside the environment.

We also explain how cloud providers implement network controls differently from on-premises models, emphasizing the importance of understanding provider-native tools. Exam scenarios will often test whether you can distinguish between coarse-grained segmentation that exposes risk and fine-grained models that achieve stronger isolation. By learning how to apply segmentation intelligently, you’ll be prepared for both practical challenges and exam questions. Produced by BareMetalCyber.com.
