We can see that most of the traffic is UDP port 53 DNS traffic but there is a little bit that is TCP port 53. To get an even better idea of the distribution of the traffic across the various hijacked prefixes, let’s take a look at a Sankey diagram.

NGFW also supports the creation of custom application definitions to enable identification of specific apps based on TCP/UDP port, IP address, or domain. Additionally, a Deep Packet Inspection (DPI) engine enables contextualization of traffic. SWG focuses on layer 7 traffic exclusively and inspects inbound and outbound flows.

NGFWs can drill down beyond IP addresses, TCP/UDP ports, and network protocols to enforce policies based on packet content. Secure Web Gateway (SWG) Web-borne malware is one of the biggest threats facing enterprise networks today.

As for IP protocols, when we look at which ones our customers are most commonly seeing on their networks (above right), it’s not surprising that TCP (protocol 6, for those not familiar) comes out on top, with almost 71% of the traffic. UDP (protocol 17) is down in the number 5 spot with only 3.2% Port Numbers and Services.
