The video tutorial explains the structure of a virtual network (VNet) with subnets and resources like virtual machines and databases. It introduces Network Security Groups (NSGs), their linkage to subnets or network cards, and the importance of managing them effectively. Best practices for applying NSGs at the subnet level are discussed, along with the evaluation process of NSGs at both subnet and network card levels. An example is provided to illustrate NSG rules for incoming and outgoing traffic on port #80.
