Hello luis,
running an IDS and monitoring it's logs should be a useful deployment , if
you still feel the threat of malicious traffic on your network.
I would even suggest having a look into latest snort-inline ;) u can do a
lot more than mere monitoring.

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
