Real-Time Network Traffic Analysis for Threat Detection

Wi-Fi is now ubiquitous in most populated areas, and the way the devices communicate leaves a lot of “digital exhaust”. Usually, a computer will have a Wi-Fi device that’s configured to connect to a given network, but often these devices can be configured instead to pick up the background Wi-Fi chatter of surrounding devices. There can always be good reasons as well as bad ones for the same, but the matter is all about the intensions. So, now imagine how many packets are flowing in a network and how harmful or useful they can be. Keeping the bad part aside, this can be used for ethical purpose as done in this work. This work follows certain steps to detect, analyze and then finally visualize the pattern of the network protocols or the data packets flowing. It also revolves around the analysis and hence, can be detected on a real-time basis.
