    For DDoS user a reverse proxy and load balance, then it's not always that easy
    For Brute Force attacks, use complex secure passwords or keys-only for access

    These are not trivial issues, of course, and they cannot be answered in a few lines on a forum like this one.

    To help with preventing brute force attacks from succeeding: Preventing Brute Force Attacks

    And to help with DDoS: How to Protect Your Network against DDoS Attacks

    Of course, these only scratch the surface - you'll need to understand the matters much better before you can take action. Use Google wisely.

    How to stop a brute force attack: Use strong passwords.

    How to stop a DDoS: You cannot stop a DDoS, only try to survive it. Best first step is to use a service such as CloudFlare. Other than that, if you get DDoS'd your host will null-route your IP and shutdown your system.

    Bastille-Linux used to be a good script for locking Linux boxes down, but looks like it hasn't been updated in awhile? Are there other lock down scripts or checklist people use these days???

    Here's my check list:
    Minimal install.
    Install only what you need.
    Configure iptables to allow only what you need.
    Use strong passwords.

    And there you have it.
