Bob Walder and Chris Morales of NSS Labs published an interesting brief. Based on last year IPS, firewall and endpoint protection tests, the effectiveness of the best device scored was 98.5%. While this is considered excellent, there is still ~2 percent of attacks that make it through the perimeter and host layer defences. Two of their proposals is to attempt to control the attacker by redirecting the attack against a target you can watch and control (i.e. tarpit the attacker) and to regularly test your network to detect problems before someone else does and exploit that system.

They have listed several recommendations but one that I think is worth focussing is be "Prepare to operate at 60 percent capacity in order to withstand a breach, which will reduce, but not eliminate, critical services." [1]

It is very likely the impact will be affecting users, customers and business. Who is prepared to continue to operate at 60% capacity without affecting business or the bottom line?

The eleven page report can be downloaded here.
