I have Net Sentinnel - Is it One of the Best?

Hi Guys,

I have Net Sentinnel 2.04 from FDW INc. as an IDS. Well, I am not much of a technical guy so I would ask if Net Sentinnel is an IDS? I mean does it fulfill the requirements of any Standard IDS? IF so then is it possible to have 2 or three IDS working at the same time or is it a stupid question?

WHat is an ideal defence system which I can implement right now and would not make me pay cash and would guarrantte me atleast 75% security from remote attacks?

I should have an IDS
I should have a Firewall
I have already implemented all the critical security updates on my windows2000 server.

PLease do guide me on setting up an Ideally Secure System. THanx in advance
