Thresholding is a wonderful thing. And no, I personally do not want
to see alerts on tings I do not have. If I am an all apache shop
then I do not turn on any IIS rules. I also make sure, via scanning
and vulnerability analysis, that I do not in fact have any IIS (or
whatever) installed. You first need to have a good inventory of what
you have. And you need to keep that up to date so you always know
what you have. Then you trim all rules to that. Weather it be
ingress - egress firewall rules, IDS configs, or whatever. Figure
out what you have, learn how it flows (and make it work/flow the
secure way) then monitor it.

Subject: IDS event filtering
I am wanting to get an idea of what you guys out there filter from
your
IDS sensors. Some of the sensors I monitor get TONS of events for
MSSQL
control overflows. If the customer is patched for slammer and does
not
have any SQL services on the internet, is it safe to filter out those
events? Do you still want to see that traffic even though you know
your
are not vulnerable? Thanks!
