  21. Internal Security To: Kassie From: Dad The IT group is

    trying to pass policies that make my remote work so much more difficult. Can you show them that I am secure? That way I can tell them to back off and let me work remotely in peace. Let’s Talk About
  22. What Happened? • Remote Access Was Enabled • Attacker Scanned

    Network • User chose a common password • Admin Did not Mitigate • Roll Through Many Password Tries Per Second
  23. If a User Can Get In, A Hacker Can Too

    Mitigation: Training and Understanding • Policies are Only as Good as They Are Followed • Train for Understanding with Compliance • Limit Access • Use Two Factor Authentication • Exponential Backoff • Monitor Stupidity is a more dangerous enemy of the good than malice. One may protest against evil; it can be exposed and, if need be, prevented by use of force. Evil always carries within itself the germ of its own subversion in that it leaves behind in human beings at least a sense of unease. Against stupidity we are defenseless. --DIETRICH BONHOEFFER
