Wireshark is a popular network protocol analyzer.

Overview

Wireshark has a rich feature set which includes the following:

  • Deep inspection of hundreds of protocols;
  • Live capture and offline analysis;
  • Standard three-pane packet browser;
  • Multi-platform: runs on Windows, Linux, Mac OS X, Solaris, FreeBSD, NetBSD, and many others;
  • Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility;
  • Powerful display filters;
  • Rich VoIP analysis;
  • Read/write many different capture file formats: tcpdump (libpcap), Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network General Sniffer® (compressed and uncompressed), Sniffer® Pro, and NetXray®, Network Instruments Observer, Novell LANalyzer, RADCOM WAN/LAN Analyzer, Shomiti/Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime, WildPackets EtherPeek/TokenPeek/AiroPeek, and many others;
  • Capture files compressed with gzip can be decompressed on the fly;
  • Live data can be read from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI, and others (depending on your platfrom);
  • Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2;
  • Coloring rules can be applied to the packet list for quick, intuitive analysis;
  • Output can be exported to XML, PostScript®, CSV, or plain text.

Network Forensics

Wireshark can be used in the network forensics process. There are some limitations:

  • Wireshark is packet-centric (not data-centric);
  • Wireshark doesn't work well with large network capture files (you can turn all packet coloring rules off to increase performance);

Wireless Forensics

Wireshark can decrypt IEEE 802.11 WLAN data with user specified encryption keys.
