Intrusion Detection recommendations

[Andy Ringsmuth <andy () newslink com>]

NANOG'ers,

I've been tasked by our company president to learn about, investigate and recommend an intrusion detection system for 
our company.

We're a smaller outfit, less than 100 employees, entirely Apple-based. Macs, iPhones, some Mac Mini servers, etc., and 
a fiber connection to the world. We are protected by a FreeBSD firewall setup, and we stay current on updates/patches 
from Apple and FreeBSD, but that's as far as my expertise goes.

Initially, what do people recommend for:

1. Crash course in intrusion detection as a whole
2. Suggestions or recommendations for intrusion detection hardware or software
3. Other things I'm likely overlooking

Thank you all in advance for your wisdom.
