Hi rustyp US = Uniform Server mod_security2 is a lil complex, but once you know the basic it so easy ( i personally use it to block UA agent and common XSS attack and nothing else ) I agree with you Harden-It is easy to setup or you can use SafeXP just to patch syn attack you can use ZBBlock with your script to add some protection or you can you .htaccess for simple protection all the best
