wireshark security update

Wireshark is an open source tool for profiling network traffic and analyzing packets. Such a tool is often referred to as a network analyzer, network protocol analyzer or sniffer.Wireshark, formerly known as Ethereal, can be used to examine the details of traffic at a variety of levels ranging from connection-level information to the bits that make up a single packet. Packet capture can provide a network administrator with information about individual packets such as transmit time, source, destination, protocol type and header data. This information can be useful for evaluating security events and troubleshooting network security device issues.

wireshark security update

Wireshark allows you to examine protocol data stored in files or as it is captured from wired or wireless (WiFi or Bluetooth) networks, USB devices, and many other sources. It supports dozens of protocol capture file formats and understands more than a thousand protocols.It has many powerful features including a rich display filter language and the ability to reassemble multiple protocol packets in order to, for example, view a complete TCP stream, save the contents of a file which was transferred over HTTP or CIFS, or play back an RTP audio stream.
