security settings on new servers

Quite new to the server setup game.

Installed a new Red Hat 8.0 machine with cpanel/whm.

How does this look for locking down and protecting a server:

Firewall (Apf or KissMyFireWall)
Mailscanner
Anti-Virus (Clam)
Port Hardening
SSH Security Measures
SIM (System Integrity Monitor)
PRM (Process Resource Monitor)
MRTG (eth0 analysis)

Opinions greatfully received.
