No.  mod_security is certainly a great tool, much more capable and flexible and effective

than what I am proposing.
But it suffers from the same issues as the one I mentioned earlier.
Have a look at :

It requires a whole setup in Apache to even start to do something.
In the practice, that means that only a small percentage of all webservers on the www will

ever install and use it, which greatly reduces any impact it will have on the www at 
large. It will totally protect the 10% of WWW servers on which it is installed, and do 
nothing to protect the remaining 90%.
So the botnets will still have 90% of the WWW webservers to scan, and this will keep them

in business. Because for the exploiters of a botnet, the "quality" of the servers into 
which they break does not really matter. A poorly-protected Linux server running only one

personal website, is just about as valuable as your high-powered 32 GB RAM 8-core monster,

when it comes to using it as a platform to attack other sites.
And most of these small, low-budget webservers will precisely be the ones which install 
the standard Tomcat or Apache via apt-get or the Windows Installer, and never change a 
standard setting.
So it should be a standard feature, and the option should be to turn it off.
