Description: A virtual network security group is a set of rules that allow or deny network traffic to resources in a virtual network. These rules are applied at the network level and are fundamental for protecting cloud resources, such as virtual machines and applications, by controlling access to them. Virtual network security groups allow defining which traffic is permitted or blocked based on criteria such as IP addresses, ports, and protocols. This provides an additional layer of security, as access to resources can be restricted to only those IP addresses or ranges deemed safe. Furthermore, security groups can be applied at different levels, allowing for granular management of network security. The flexibility of these groups enables network administrators to tailor rules to their organization’s specific needs, facilitating the implementation of robust and effective security policies. In the context of cloud computing, virtual network security groups are essential for managing the security of resources across multiple environments, ensuring that connections between cloud and on-premises resources are adequately protected.
