security for server spammers/hackers

hi!
does anybody had any idea about a software that automatically blocks a specific IP after he/she tries to access, say twice or thrice, the server using passwords? after failed accessing, it will automatically save the ip and tagged as block ip?

or if not, what other options do i have to secure a server from unwanted scripts.

i hope to hear from you.


thanks!
