Re: [FW-1] sniffing network
Got one thanx
Using fw1 to create dmz.
It looks like the servers are safe, what I'm really worried about is guys
using my network for relaying, spamming, and my bandwidth in general.
I am taking steps for the spamming and relaying. Hopefully this will
discourage more bastards from sniffing my network.....

I'm afraid that you may need to take drastic actions, i.e. Fdisk,
format,
reinstall... As a interim step, to help prevent further damage, find
out the
ports that the sniffers and probes talk on and block their access
to/from
the outside world. After that, if you want to avoid the fdisk
solution,
talk to your antivirus vendors, intrustion detection vendors, and
other
security sources to see what help they can offer. If you don't have
antivirus software installed on servers, desktops, and gateways, get
it
asap! Implement policies about outside software and files to help
prevent
further infiltration. Just a start, but as they say, "A journey of a
thousand miles begins with the first step."

Greetings all
I have just started with a new company and to my horror discovered
that the
network has been infested with sniffers and probes. Conventual anti
virus
software does not detect these encoutered, any ideas how I could go
about
combating these bastards????
I have been able to find out whre most of them are, but failed to
get rid of
them.
PLZ HELP
