It is my understanding that the "usual suspects" of network controls do not perform the right preventive activities at layer seven. The purpose of the network controls is to make sure that application input gets to the application securely, with integrity, when needed. They do not verify that the input is appropriate for the application or safe. That could be the job of an Application Firewall. See the following web link contained in an excerpt from my GSNA practical in which I performed an application audit: (http://www.giac.org/certified_professionals/practicals/gsna/0184.php).
"Application Firewalls - There are a number of application firewall products that could offer protection for existing and new web applications. Network World Fusion (www.nwfusion.com/_bg/2004/appsecurity/index.jsp) rated and compared ten application firewall products. Purchase prices for the reviewed products range from $1,295 to $35,000."

To your question about "How can we optimize security?"
One of the elements often mentioned is about "application security". I think this concept should be split into two components:
1 - building "secure" applications, meaning application that cannot be easily penetrated and that cannot induce risks into other applications they interact with.
2 - making sure that the required "network security" with the firewalls, IDS, IPS and all the alphabet soup, be completed by a security network acting at the application layer, not at the transport layer. This way, no malware can penetrate or cause harm to the "application". One must remember that 75% of successful attacks aimed at the Application layer, not at the network layer (Gartner)
