Re: Intrushield

I've worked with Intrushield for a while now and I am not impressed
that you must use their java GUI. In regards to filtering traffic,
what I do is use NetForensics and add the sensors to a filter on its
event console in the SIM. Within NF you can filter whatever you wish
out of the Intrushield alerts and it also helps with your logging
issue, should you have the luxury of using a correlation engine such
as NF or something else like ArcSight. Unfortunately, these products
are all java based as well.
