Network Sniffing: Using Wireshark to Find Network Vulnerabilities

Sniffers are certainly nothing new, but can they be used to discover serious misconfigurations in our networks? Yes!

All I can say is that the methodical approach demonstrated in this video has come in real handy and I can't thank you enough for making this video. Super educational!

[xLatinAssazzin]

Thank you so much for making our days better with your videos!

That was a good video on breaking down network traffic to get to a problem.

You can run Wireshark in promiscuous mode, and it will show you all the traffic that is being broadcasted. However you still must have access to the network for this to work (so you can't automatically sniff a secured network) and if you're on a switched network, you'll only receive traffic bound for your system.

Thanks for the help on network vulnerabilities.

A few years old now but still very relevant. Nicely done.

Thank you for this thoughtful tutorial it does help me to understand wireshark better. You helped to short-cut.. tx again triple thumbsup.

[shaunfielding]

Thank you for this. Good work, makes Wireshark more valuable.

[isaakjananel]

Great video David, can you recommend other video to learn more about Wireshark. I'am a beginner using Wireshark. Thank you

[meyerjohannes]

Am I the only one noticing the pornography bookmark?

Nice vid though.

As an alternate you might find Fluke Networks ClearSight Analyzer easier to use.

[rlyen]

Very good tutorial, thank you for sharing!

[ryanp]

Do you know a way to detect network loops easily in a large network? RSTP us enable so helping but I need to find the loop without running around.

I am a student starting my computer networking degree . Could you please suggest me how can learn more about network security, pen testing etc .. any certifications?..am from UK

[harness_]

so this is to scann your own network? but how do I scan someone else's network?

[rahulchawla]

from this all, how we will be able to find the vulnerabilities in the network. ??

[randystauber]

Great video. 

I can't seem to find anything to backup that a WINS server will eliminate NBNS broadcast. You got any documentation for that?

[BetterDayzMusic]

Hiii, thanks for another great tutorial. Please, I have a question. Does Wireshark capture any wireless traffic such as wifi, or cellular? Thanks in advance!
