<p class="MsoNormal">I am looking at building a snort server to sniff my internet traffic.  If anyone has the time and/or the inclination I would very much appreciate any input you may have.<o:p></o:p></p>
<p class="MsoNormal">Any server I use would need to be able to deal with constant ~250 Mb/sec of traffic as well as peak between 450-500Mb/sec.  Also there is the distinct possibility that I will be upgrading my bandwidth to 1Gb/sec and adding an Internet 2
 link as well @ 2x1Gb/sec. Please volunteer your thoughts on the following:<o:p></o:p></p>

</span></span><![endif]>Normally where would you deploy a SNORT IDS?  My thoughts are to deploy it out of band using a monitor session on the internet switch, with a dedicated management interface for sending emails and such from the snort box. Basically setting
 it up as a tap on the outside interface of my firewall.<o:p></o:p></p>

</span></span><![endif]>What kind of hardware do I need?  Since this is my internet sniffer it will be seeing some rather exotic traffic and will need some careful tuning to get right.  I would like to be able to use as many rules as possible, but more rules
 = more CPU and RAM.  Given that, what kind of hardware am I looking at to be able to use a good and thorough rule set while not getting bogged down under peak conditions (theoretically about 3Gb/sec).<o:p></o:p></p>

</span></span><![endif]>Homebrew vs. Vendor.  Sourcefire makes what I consider to be the gold standard of snort based IDS … or IDS in general. But, is the GUI and support necessary?  If I can successfully demo and deploy this tech on a homebrew box could I
 get professional support without buying the hardware from a vendor like sourcefire, or should I skip the roll-your-own setup and go for broke with a fully supported platform first?<o:p></o:p></p>
