CPanel server - How to automatically ban IP range after x number of failed attempts?

Everyday I get at least one or two "large number of failed attempts" emails from my CPanel server and normally I just log in to ban the IPs myself. However, at some point I start to get tired with it and I am just wondering if there is any way I could ban the IP range (i.e., the /24) permanently should there be, say, more than 5 failed attempts from this IP?
