    9. 9. Today’s agenda Planning Determine risks Fortify Test/Document The elements, issues and challenges with planning Hackers are only one concern – there’s more Chances are GOOD you are exposed somewhere to attack Test and Documentation is vital to a healthy plan Communications Who needs to be informed, how to inform, Media/Press Ω
    10. 10. Determine Risks <ul><li>What ‘could’ go wrong? </li></ul><ul><ul><li>Hardware/Software Failure, DNS, Hackers </li></ul></ul><ul><li>What can you do to mitigate it? </li></ul><ul><ul><li>Hot site, backups, planned recovery </li></ul></ul>
    11. 11.

    13. 13. Affordability of a Risk <ul><li>Elements to consider </li></ul><ul><ul><li>How much $$$ are you willing to spend </li></ul></ul><ul><ul><li>Does management buy into your plan? </li></ul></ul><ul><ul><li>Are they willing to commit to it financially? </li></ul></ul><ul><ul><li>Does your site “justify” a DR plan </li></ul></ul><ul><li>Determine if risks JUSTIFY cost </li></ul><ul><li>At the end of the day, if you have a blog site, </li></ul><ul><li>then perhaps its not worth it.

    14. 14. Why do need a plan? <ul><li>Recognize that trouble WILL come </li></ul><ul><ul><li>Mr. Murphy on line one for you… </li></ul></ul><ul><li>Your plan should be : SMART based </li></ul><ul><ul><ul><li>Specific, Measurable, Attainable, Realistic, and Time-sensitive </li></ul></ul></ul><ul><li>&quot; A good plan, violently executed now, is better than a perfect plan next week .“ </li></ul><ul><li>General George Patton </li></ul>

    28. 28. Fortify - Poor Host Security <ul><li>Example: Ports open that need not be </li></ul><ul><ul><li>Real case from JoomlaRescue.com Client </li></ul></ul><ul><ul><ul><ul><li>The host had 1,700 ports open. </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Port 53 – Allows for Zone Transfers </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Port 23 – Telnet – Allowed “Banner Grabbing” </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Port 21 – Allowed me (shouldn’t have) to FTP in </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Port 6667 (note BackOrfice) – Cult of the Dead Cow </li></ul></ul></ul></ul><ul><ul><ul><ul><li>And 1,677 more – (HUN???) </li></ul></ul></ul></ul><ul><ul><ul><li>Host told client: </li></ul></ul></ul><ul><li>“ That’s ok you have a Virtual private Server (VPS) setup” </li></ul>
