Network Security Groups
Network Security Groups (NSGs) serve as centralized firewall policy managers, enabling the filtering of network traffic to and from virtual network resources within a given Virtual Data Center (VDC).
An NSG contains security firewall rules that allow or deny ingress (incoming) and egress (outgoing) network traffic for Network Interface Cards (NICs) or Virtual Machine (VM) resources configured as NSG members. Each rule can specify the source and destination, port, and protocol.
Note: Network Security Groups are currently accessible only via the Cloud API v6. The DCD support will be available soon.
