The Enemy Within: Firewalls and Backdoors

hrbrmstr writes "SecurityFocus is running an article on firewalls and backdoors on their InFocus site. They provide info on firewall types, backdoor classifications, some examples of real backdoors and tips on mitigating their use on your network." Some good topics explained for the beginner, and it's a nice refresher for the veteran admin as well.

    I was pretty sure they did it missionary style, but then again, I've only seen it the once.

    All hail the pepper jack.

      You mean some.insecure.host.org at 216.74.108.110? I hope that it's like example.com, and meant to be used like this. (Hmm, FTP server running there. :^)

    I remember the time when we found out that the 3Com switch / router / whatever (i can't remember so clearly now, it's been such a traumatic shock that i am still trying to forget and having mild success), and we were basically like "WHAT?!?!" and then all passed out.


    I remember this time I was all drunk and busy trolling slashdot and I got to this article that was related to what I do for a living, only it was related in the most remedial of fashions and I was like "right on, I can troll this motherfucker like it ain't nobody's business, fo shizzle mah nizzle, and I may even get mod points cuz of the bullshit I'm about to spew."

    Anyway, I was reading this mofo and I came across some whack job herion addict post that said some stupid shit and I read it and reread it and reread it, and was like "well, I'd troll this sumbith, but the wanker can't even write coherently". So I read it again and was basically like "WHAT?!?!" and then I was all passed out.

    "It is a concrete fact that that no MacOS based webserver has ever been hacked into in the history of the internet."

    That's because there is a grand total of 1 (ONE) MacOS based webserver(s) on the internet.

    Actually, the most common sexual style is ::drumroll:: doggie style.

    That's where the man sits up and begs and the woman rolls over and goes to sleep.

    If only I could do that self-licking thing, like they do afterwards. Why do they even bother with the middle?
