Does each network security group (NSG) rule need to have a unique name?

In Azure networking, each network security group (NSG) rule is required to have a unique name within that NSG. This uniqueness is essential for clear identification and management of the rules, as it allows for easier troubleshooting and updating of rules. Unique names help prevent confusion among rules, particularly in scenarios where multiple rules might have similar attributes or purposes. By enforcing the requirement for unique names, Azure ensures that administrators can quickly and accurately refer to specific rules when configuring security policies or diagnosing issues, thereby maintaining efficient operation and security of the network.
