    73% came across a misconfigured network more than three quarters of the time – which, according to 76% of the sample, was the easiest IT resource to exploit.

    So are we to believe that 73% is more than three quarters, or is this a case where 90% of IT is half-mental?

    • There's nothing wrong with that. It means that 90% of the IT tasks are half mental, whereas the other 10% of the tasks could be completely mindless or 90% mental.

IT and mental processing aren't so tightly bound as to make that line of reasoning sound.

      That's a bit general. Say you want to run a Samba fileserver to share files among Windows clients. You'd want the fileserver on your internal network to accept connections from the relevant ports. You would not want the firewall standing between your network and the Internet to also have that port open to the world.

      While it's true that a conscientious admin would tighten up the Samba server's firewall by specifying both ports and IP addresses/ranges (or other credentials) that are acceptable, you still wouldn't have identical policies between the internal systems and the firewall controlling what can connect from outside.

        Network audits.
        It's right there in the summary.

        Detection and mitigation of penetration is equally as important as trying to prevent the intrusion in the first place.

    • The correct answer is to put the ASA in front of an ISA or TMG server, and use it only for packet inspection and port blocking. Forward only the necessary ports for your business, and whatever is allowed is explicitly enabled AND authenticated by domain\user.

      That way, nothing gets in OR out that is not expressly permitted, or tied to a specific user account. An internal effected machine cant send anything out the gateway if its not via 8080 with the firewall client, and with a rule naming its executable.

    How is the network to blame here? Someone screw up spanning tree, OSPF not using md5 authentication? DHCP mis-configuration? DNS? Wrong gateway used? What? The article gives nothing, just like most of the sysadmins and managers that come to my desk crying about how slow scp/nfs/smb copie

    I was at Defcon this year (like always), and the people conducting this study were essentially paid per response, which I'm sure is quite common. We were standing on the Riv steps, during one of our many cigarette breaks, and some girl came up and asked us to do her survey.

    Us: "This question doesn't really make sense."
    Her: "Just check any box, I need to get them all filled."

    And that's basically how it went. The question/answers seemed a little silly, and there were a lot of excluded middles. The surveyors knew nothing of the questions, and were just trying to get out there of (can't blame 'em). The answer space was a checkbox, and if you saw it, you'd see how easy it'd be to just fill out the rest of the boxes with similar answers if you wanted to go home.
