In an Azure virtual network, network traffic between Azure services can be filtered using an Azure network security group. Security rules that permit or prohibit network traffic entering or leaving certain kinds of Azure resources are contained in a network security group. You can set the protocol, port, and source and destination for each rule. By grouping virtual machines and defining network security policies based on those groups, application security groups let you establish network security as a logical extension of an application's structure. Scalable security policy reuse is possible without the need for manual IP address maintenance. With the platform, you can concentrate on your business logic while it manages the intricacy of various rule sets and explicit IP addresses. Traffic is routed by Azure between its resources, on-premises systems, and the Internet. For every subnet on an Azure virtual network, Azure automatically generates a route table and populates it with the system default routes. The system adds a route for each address range inside the address space of each virtual network engaged in the peering when you construct a virtual network peering between two virtual networks. The versatility of NSGs is highlighted, emphasizing their applicability to a spectrum of scenarios, from small-scale applications to complex enterprise network architectures. By tailoring NSGs to specific security requirements, organizations can establish a robust defense mechanism, protecting sensitive data and workloads from potential security threats. Furthermore, the abstract underscores the collaborative nature of the Azure ecosystem, wherein the community and support team stand ready to assist users facing challenges in implementing NSGs. Leveraging features like service tags and application security groups enhances rule management and contributes to a layered security approach, aligning with Azure's commitment to comprehensive defense strategies.
