Wireshark: An overview of the topics we have discussed in detail **

In the field of the network analysis and cyber security, Wireshark rightfully occupies a place of the leading application. This is a free, unencumbered network protocol analyzer that provides deep visibility into every communication on a network: a critical tool for network and security managers and other technical professionals.

What is Wireshark?

Wireshark is as generalized network analysis tool that involves capturing and analyzing data packets as they flow through a network in real-time. It means this tool works as a ‘glass loupe’, which helps you investigate every detail of the data flow on your network. No matter whether you have to face problems in networking, or there is a need to secure infrastructure, or even starting with the idea of network protocols, Wireshark will cater all your requirements.

Why Use Wireshark?

One of the many features of Wireshark is the real-time packet capture that is available to users. It is possible to observe and even capture network traffic while it is going on and this makes it possible to diagnose a situation while it is processing. Also, Wireshark provides ** analysing data offline ** that makes the users copy the data to his or her computer for further examination. This is especially valuable for analysis of older video or to share the capture with other colleagues for the investigation of a common issue.

The intense packet analyzer available in the tool supports interface of hundreds of protocols and provides detailed specification about dissecting packets structure and contents. To aid in making sense of all the captured data, Wireshark has advanced display filters through which the users can focus on certain kinds of traffic or problems. In addition, coloring also increases the legibility of the current stream since bursts of various packets are colored differently, and their different color makes it easier to find deviations.

As the world moves forward and network security and performance become more critical, it’s essential tools such as Wireshark are on every working network analyst’s list. No matter you are in charge of a complicated network issue or building up a stronger security line, Wireshark proves itself as an indispensable tool because of its full range analysis functions.
