Re: analysing captured packets

Hi
Thanks for the suggestions, looks like I'll be busy for a while. Don,
your papers look good I'll have a read through.

I've also had a look at the honeynet challenges and this one is the
one for beginners and packet analysis
http://www.honeynet.org/scans/scan23/ , from a quick look at the top
answer, he has come up with a very detailed analysis of the file. So I
know where I'm aiming, how long would people suggest that it would
take to get to this level of knowledge? The person answering says he
is a beginner but from his answer he is obviously a better level of
beginner to me! Obviously this depends on background and how much you
study, but is the person answering the questions likely to have a
months worth of experience or 6 months? When studying on my own I'm
always my own worst critic and feel that I'm picking things up too
slowly!

And pagvac, I will be, I just wish there were more hours in the day!

Thanks

Robin

I know that what I'm gonna say may sound silly, but what I recommend
you is simply to play with analyzing traffic A LOT. Just watch the
packets, filter them by protocol, IP address, or whatever you're
interested in (Ethereal is great for filters). Try to follow different
protocol "conversations" and try to understand what the requests and
responses mean.

Good luck on your sniffing experience my friend :-)

Hi Can anyone give any pointers to good tutorials on how to go
about analysing network traffic captured during a pen-test.

I'm currently using ethereal but I'm not necessarily looking for an
 ethereal tutorial more a howto on what to look for in capture
files. Things like good protocols to spot (e.g. ftp logs in in
plaintext so you can grab login details), how to recognise what is
going on by watching the high level handshakes (e.g. a http get is
usually followed by a response containing html), things like that.

Thanks

Robin
