If your computer is always connected to the Internet or local network, it's vulnerable to hacker attacks and malware infections. In addition to using a powerful and updated antivirus solution (obligatory for any responsible PC user), you can also use a network analysis tool to identify the malicious packets and block them. Such an application is Wireshark and it's free to use.
Customizable setup pack
When deploying Wireshark on your computer, you can choose the plugins and extensions you want to install, such as the Dissector plugin, Tree Statistics, SNMP MIBs, or the Meta Analysis and Tracing Engine.
Since these utilities are meant to provide a wider range of information about your network traffic and they can be easily disabled, it is advisable to install them alongside Wireshark. The same advice applies to the extra tools bundled with the setup and to the recommended file associations for trace files found on the PC.
The final step before finalizing the initial configuration is for the setup to check whether you have WinPcap installed on your computer, and to install it if missing.
Set filters to capture network traffic
If you are using several network cards, Wireshark lets you choose the one for capturing the network traffic. Once the capture has begun, you can monitor all the connections and their corresponding details – you also get the chance to create filters to keep an eye on just certain types of connections.
Color-coded packet types to spot them easier
Another way to make sure you correctly monitor the type of packets you want is to apply color schemes for each type of connection, so that the most important ones are the most visible. If you are not satisfied with the color templates provided by Wireshark, you can create a custom one by specifying the shade and string to be monitored.
Wireshark also comes with a Statistics function that can be used to generate reports to be analyzed at a later time. Depending on your necessities, you can choose to view the details of the protocol hierarchy, endpoint, packet lengths, or the IO graph.
Overall, an advanced and dependable protocol analyzer
With all things considered, Wireshark can come in handy to all those who want to be in control of their network connections and limit them whenever needed. However, it does take an expert to use the app to its full potential.
FEATURES
• Data can be captured "off the wire" from a live network connection, or read from a capture file.
• Wireshark can read capture files from tcpdump (libpcap), NAI's Sniffer (compressed and uncompressed), Sniffer Pro, NetXray, Sun snoop and atmsnoop, Shomiti/Finisar Surveyor, AIX's iptrace, Microsoft's Network Monitor, Novell's LANalyzer, RADCOM's WAN/LAN Analyzer, HP-UX nettl, i4btrace from the ISDN4BSD project, Cisco Secure IDS iplog, the pppd log (pppdump-format), the AG Group's/WildPacket's EtherPeek/TokenPeek/AiroPeek, or Visual Networks' Visual UpTime. It can also read traces made from Lucent/Ascend WAN routers and Toshiba ISDN routers, as well as the text output from VMS's TCPIPtrace utility and the DBS Etherwatch utility for VMS. Any of these files can be compressed with gzip and Ethereal will decompress them on the fly.
• Live data can be read from Ethernet, FDDI, PPP, Token-Ring, IEEE 802.11, Classical IP over ATM, and loopback interfaces (at least on some platforms; not all of those types are supported on all platforms).
• Captured network data can be browsed via a GUI, or via the TTY-mode "tethereal" program.
• Capture files can be programmatically edited or converted via command-line switches to the "editcap" program.
• 602 protocols can currently be dissected
• Output can be saved or printed as plain text or PostScript.
• Data display can be refined using a display filter.
• Display filters can also be used to selectively highlight and color packet summary information.
• All or part of each captured network trace can be saved to disk.
New in version 2.00 RC 2 (October 31, 2015)
• Several dissector and Qt UI crash bugs have been fixed
Qt port:
• The SIP Statistics dialog has been added
• You can now create filter expressions from the display filter toolbar
• Bugs in the UAT prefererences dialog has been fixed
SYSTEM REQUIREMENTS
• WINPCAP 4.X (INCLUDED IN THE SETUP)
• Any modern 32-bit x86 or 64-bit AMD64/x86-64 processor
• 200 MB available RAM. Larger capture files require more RAM
• 75 MB available disk space. Capture files require additional disk space
• 1024x768 (1280x1024 or higher recommended) resolution with at least 16 bit color. 8 bit color should work but user experience will be degraded
• A supported network card for capturing
OS: Windows Vista / Vista 64-bit / 7 / 7 64-bit / 8 / 8 64-bit / 2003 / 2008 / 2008
