Wireshark/Protocol Analysis
From charlesreid1
Protocols
Another way to analyze traffic in Wireshark is to look at statistics about the protocol layer.
You can open Statistics > Protocol Hierarchy to see information about what protocols are used in what amounts.
This can be useful if you are trying to determine "normal" behavior for a network, and then trying to determine if a particular day's traffic is an outlier and why.
By looking at a network's traffic protocol statistics, you can learn a lot about that network. Example: IT department will have admin protocols like ICMP or SNMP. Ordering department will use lots of SMTP. Interns will use WoW.
