Long story short while watching a movie some time we came across characters with unfamiliar ascent which we are not used to and we can’t pick up their dialogues so we use subtitle feature likewise as security folks we come across a versatile situation where we are unable to grasp the happenings around the network  in this scenario we need additional tools to understand what’s going on to break the mystery.

There are many tools can be used but we will be going to learn most common tools run by security professionals.
