I am new to the grsecurity patch. I need to harden 3 of my Linux RedHat 9.0 Servers to perform 3 basic task (DNS - Bind 9.#, FTP - vsftpd, and News - Dnews). What setting for the grsecurity can I use (low, medium, high, custom) can I use when I recompile my kernel so I know the added security is not going to break any of the application
