Description: Zonal isolation is a technique used to separate different zones within a network to enhance security. This strategy involves creating segments within the network infrastructure, where each zone can have specific security policies and access controls. By implementing zonal isolation, organizations can limit lateral movement of threats, ensuring that an attack in one zone does not compromise other parts of the network. This technique is particularly relevant in virtualized environments, where multiple services can coexist on the same physical infrastructure. Additionally, zonal isolation integrates with network security practices, allowing for a more effective incident response and facilitating compliance with regulations. In the context of cloud services, zonal isolation can be applied through the creation of subnets and security groups that control traffic between different resources, thereby enhancing the overall security posture of the organization.
