#Wireshark-Sniffer, network protocol analyzer, and network analyzer

• Wireshark is an open-source packet analyzer, which is used for education, analysis, software development, communication protocol development, and network troubleshooting.

• It is used to track the packets so that each one is filtered to meet our specific needs. 

• It is also used by network security engineers to examine security problems.

• It is a free to use application which is used to apprehend the data back and forth. 

• It puts the network card into an unselective mode, i.e., to accept all the packets which it receives.

• It is used by network security engineers to examine security problems.

• It allows the users to watch all the traffic being passed over the network.

• It is used by network engineers to troubleshoot network issues.

• It also helps to troubleshoot latency issues and malicious activities on your network.

• It can also analyze dropped packets.

• It helps us to know how all the devices like laptop, mobile phones, desktop, switch, routers, etc., communicate in a local network or the rest of the world.

• It is multi-platform software, i.e., it can run on Linux, Windows, OS X, FreeBSD, NetBSD, etc.

• It is a standard three-pane packet browser.

• It performs deep inspection of the hundreds of protocols.

• It often involves live analysis, i.e., from the different types of the network like the Ethernet, loopback, etc., we can read live data.

• It has sort and filter options which makes ease to the user to view the data.

• It is also useful in VoIP analysis.

• It can also capture raw USB traffic.

• Various settings, like timers and filters, can be used to filter the output.

• It can only capture packet on the PCAP (an application programming interface used to capture the network) supported networks.

• It supports a variety of well-documented capture file formats such as the PcapNg and Libpcap. These formats are used for storing the captured data.

• It is the no.1 piece of software for its purpose. It has countless applications ranging from the tracing down, unauthorized traffic, firewall settings, etc.
