IDS: RE: IDS event filtering

RE: IDS event filtering

AFAIK this is the best list on securityfocus for SIM. The management
and incident handling lists appear to be moribund. There's also
occasional SIM-related traffic on the logs list at shmoo.com. If there
are other lists that folks like to track for activity related to SIM, do
suggest them here.

Otherwise, would anyone be interested in a separate SIM list at
securityfocus? If there's enough interest (vote now!) I suppose we can
get one started. Otherwise it seems to me that this is the right place,
given the overlap in the goals of SIM and IDS/IPS.

Is there any mailing list for discussion of SIMs, or does that pretty
much
fit under this list still? (There's quite a bit of overlap in concepts
and
technology).
