/me agrees with David Lang (must be a first...) More to the point of your question: * shutdown unnecessary services * block unnecessary ports * upgrade/update packages * get a CRC fingerprint for various parts of the system (/etc, /bin, etc.) - and periodically check the running system against it. * backup critical parts of the system (see above)
After that it's a matter of change/security management: detecting intrusions, finding the vulnerabilities, restoring to the pre-cracked version, fixing the vulnerability, and making another checkpoint.
