Interesting point.What would be your suggestion(s) to strengthen security in a production environment according to your experience ? At the moment I mostly rely on redundant single defenses to slow down potential intrusion so that it gives me some precious extra time to react and isolate the LAN. However I can feel how weak and unsatisfying such a system is when uptime matters, since this "strategy" implies a rather long recovery time...

Just remember this aphorism - Depth without Breadth is useless. We engaged in a series of experiments within the DARPA IA program in which we proved that Defense in Depth is an over-rated concept. Layered defenses can actually be weaker than single defenses because administrators/developers think that another layer is providing the defense they are ignoring. The results of these experiments were recorded in a paper, unfortunately I don't have a cite at this time. Bottom line - we were able to get through layers of defense in depth because we could attack each layer in a different way. This allowed attacks to woogle through to the goal despite multiple layers of defense.
