 What is Wireshark
 Where it use
 How it works
 Some practical things

3. What is Wireshark?
- Network packet/protocol
analyzer
- One of the best open source
packet analyzers available
today for UNIX and Windows

4. You could think of a network packet analyzer as a
measuring device used to examine what’s going on
inside a network cable, just like a voltmeter is used
by an electrician to examine what’s going on inside
an electric cable (but at a higher level, of course).
Wireshark is perhaps one of the best open source
packet analyzers available today.

5. Where it use?
- Network Administrators use it to troubleshoot
network problems
- Network security engineers use it to examine security
problems
- Testers use it to detect defects :)
- People use it to learn network protocol internals.

6. WireShark – Sample Demo

7.  A vulnerability scanner is a computer
program designed to assess computers,
computer systems, networks or
applications for weaknesses.
They can be run either as part of
vulnerability management by those tasked
with protecting systems - or by black hat
attackers looking to gain unauthorized
access.

8. The following are some of the many features Wireshark provides:
•Available for UNIX and Windows.
•Capture live packet data from a network interface.
•Open files containing packet data captured with tcpdump /
WinDump,
•Wireshark, and a number of other packet capture programs.
•Import packets from text files containing hex dumps of packet
data.
•Display packets with very detailed protocol information.
•Save packet data captured.
•Export some or all packets in a number of capture file formats.
•Filter packets on many criteria.
•Search for packets on many criteria.
•Colorize packet display based on filters.
•Create various statistics.
... and a lot more!

9. How it works?
For Windows
- download
(http://www.wireshark.org/download.html)
- install
- use

11. Open Wireshark. Click the "Capture" menu, then click
"Interfaces." A small window with all of your networking
interfaces will appear. If you use any network traffic, you
will start to see packets coming in.

16. HTTP Analysis

17. HTTP Analysis – Load Distribution
Click “Create Stat” button
You can add “filter” to only
Show selected traffic

18. HTTP Analysis – Packet Counter

19. HTTP Analysis – Requests

20.  Each line represents a packet, and there are 7 columns that
provide information about it is number column shows the
order of the packet when you start recording network traffic.
This is to provide you with number reference so that you
can easily identify particular packet.
 The time is in seconds, up to 6 decimals, when the packet
was received after you started to record network traffic.
 The source includes the Internet Protocol (IP) address of the
packet's origin.
 The destination IP records where a particular packet is
going.
 The protocol the packet uses. The most common are TCP,
UDP and HTTP.
Examine each packet's information.
