I'll second ketchup's response... and his question. What exactly are you looking for? The topic can be VERY general, and without some specifics, it's hard to point you in any given direction.
For instance, are we talking security as in policy / procedure / posture, or physical / logical security, or something a little more specific, pertaining to a specific regulation or mandate, such as HIPPA, COBIT, PCI?
