Subject: network worm

Hi all,
in the past days our network was stressed from a lot of network worm (not
find from local antivirus, already up to date) with a stop of the traffic
caused from a lots of arp request. The last one was the WORM_SDBOT.ACJ a
worm that propagates itself using network shares and a worm that trend micro
(up to
date) was unable to find, causing the saturation of the network switches and
the related stop of all the work. The question is: "is there the possibility
to setup an instrument (even linux based) to sniff the network traffic with
capabilities to find worm?". We have already a linux based tool for network
monitoring, this tool is useful to isolate host with a lots of ARP request
(typical of the worm), but this tool can't point us to which worm is doing
the traffic.

Thanks a lot
Luis
