 Network Security Group flow logs provide information that can be used understand ingress and egress IP traffic on Network Security Groups. These flow logs show outbound and inbound flows on a per rule basis, the NIC the flow applies to, 5-tuple information about the flow (Source/Destination IP, Source/Destination Port, Protocol), and if the traffic was allowed or denied.
