Introduction to Packet Analysis - Part 1: Network Protocols

Author: Jeremy Druin
Twitter: @webpwnized

Description: From the ISSA-KY Network Packet Analysis Workshop, this video introduces the basics of the OSI packet model, application packet model and common network protocols. Later videos will discuss specific protocols such as TCP, IP, UDP and HTTP. Later, packets will be captured into PCAPs which are analyzed with Wireshark and Network Miner.

The webpwnized YouTube channel is dedicated to information security, security testing, and ethical hacking. There is an emphasis on web application security but many other topics are covered. Some of these include forensics, network security, security testing tools, and security testing processes. The channel provides videos to encourage software developers and system administrators to perform security testing. Also, the channel educates the next generation of security testers and bug bounty hunters who want to respectfully, legally, and ethically help system owners who allow security testing.

4 minutes in and I am already blown away by the easy to understand language about the presentation layer. first time it finally clicked for me, thank you!

[Chromium_]

This is simply classic !! hats off to Jeremy Druin

[johnmagee]

This is the first tutorial I've found that really breaks this down with simple language, under the assumption that I don't know anything - which is very greatly appreciated. Thanks

[thilinaavishka]

Man this video is a life saver. This is the first time these things made sense though i was learning through a whole semester. Thanks

[l.p.]

I've watched ~12 hrs of Intro videos related to packet analysis and understanding Wireshark and this is in the top 2 or 3. Good job breaking it down.

[dark_red_blood]

Thanks man, 6 years late but rather late than never❤

[paulligatto]

Well it ain't Fast and Furious, but it is the best explanation of these layers I've ever come across. First time I feel like I understand them somewhat.

[grjesus]

Hats off to you sir. This is what I was looking for, the big picture of how packets are transmited. Thanks!

[bluedamon]

Hey, Jeremy I appreciate your time on doing this. Your 'You Tube' video has become the beginning standard for my IT soldiers before I let them loose on Network Analysis tasks !!!

[wolfrevokcats]

Nice, not many tells about raw packets. Keep up the good job Jeremy

15:55 the first 12 bytes in the Packet Bytes pane starting from 00 0c 29 ... refer to the MAC address of destination & source address

[vextronx]

This is incredibly helpful, thank you!

[NickMcElmurry]

I love learning about this stuff.
thanks

[iandrake]

Where does the source and destination addresses start? (192…) & (64…)

[turnnamtaslim]

I want to analyze different protocol like eigrp osp and want to show output on graph which tool should I use for this ?

[TechGuidebro]

such less views for this perfect video !

Question, at 39:10 you explain that 04 f9 is equal to Scr Port: 1273. How is this number calculated. I keep getting a different number.
