I hope you are ready to start analyzing packets using different filtering options present in Wireshark and to reuse the filters that we previously created in a user-defined profile. I will be guiding you with a technique to filter packets based on certain expressions, which we will create using different primitives that are available.

Before we go ahead and start creating awesome filters, I want to mention one more interesting tool that is used to find packets: the find...
