# Network Security Group

A Network Security Group (NSG) in OCI is a virtual firewall that lets you define and enforce security rules for a set of cloud resources. It provides fine-grained control over both inbound and outbound traffic at the virtual network interface level, independent of the subnet's security rules. NSGs make it easier to apply consistent security policies across multiple resources without changing subnet configurations.
