RE: DOS attacks

This probaly should be sent to the forensics mailing list.
However, you need to investigate just what happened. Was there a vulnerable service?? did they compromise root?
There are forensics tools like sleuthkit and the webfront to those tools called autopsy. But you need to first figure 
out how you want to respond to the incident, and perserve the evidence as best you can.
This is in case the server is production and can not be disconnected.

Are there any forensic type tools to assist me in the following situation.
 
I have a small group of my Internet customers attacking an external web
server. Rather than just cut them off - I've spoken to the server admin and
received his syslogs.. what I would like to do is to get to the root cause -
whether it be purposely or a worm/Trojan..
Thus far - I've retina/nessus scanned, profiled the traffic to the server
(to get a packet/ bandwidth total) .is there anything else you can recommend
?
Any comments will be greatly appreciated .
 Regards,
 
paul
