In principle,

I use 2 method to protect the Windows and Linux server
1. Prevent all unnecessary access, physical and logical
- Lock up your server, don't allows remote access.  Use ssh with certification authentication control if it is cannot be prevents
- Disable all unnecessary and service running, like ntp, smb httpd etc etc.
- Never expose a  Windows server to the internet without a firewall.
- Use selinux to control access to files. and write programs with checksum or tripwire checking to those webpage and home directories if necessary.
2. Use VMs, control one service in one VM, can control accesses.  keep snapshots so you can recovery anything easier
