    nt offline passwd cracker security

    Hey guys My teacher showed me a program called Nt Offline Passwd Cracker from http://home.eunet.no/~pnordahl/ntpasswd/bootdisk.html. I was wondering is there anyway to block this besides a bios password.

    I couldn't get to the site so I'm not sure what the program does but here's a great resource on how to secure all types of servers.

    If a person has phisical access to the box and is malicious, you already lose.

    That is why phisical security is just as important as digital security.

    Well, as XTC46 correctly observes, if someone has physical access you are doomed That is why servers are generally kept behind locked doors.

    Here is an interesting site on the subject:

    http://www.petri.co.il/reset_domain_...ws_2000_ad.htm

    I would point out the distinction between "cracking" a password and "re-setting" it. If a malicious individual re-sets a password, they advertise their intrusion.

    If you cannot do someone any good: don't do them any harm....
    As long as you did this to one of these, the least of my little ones............you did it unto Me.

    There actually is a way to block this. I'm not up to speed on how but rest assured that it is possible. I witnessed a friend try it at our local library and when he rebooted the system The disk didnt have any effect? I think it may have something to do with disk partitioning.
    "Do you know why the system is slow?" they ask

    "It's probably something to do with..." I look up today's excuse ".. clock speed"

    If it was in a library, the most likely method is to physically disconnect the drive. Otherwise go into the BIOS and remove the floppy from the boot sequence..............you would have to password protect the BIOS for that to be effective.

    Treanglin:

    With physical access to the computer there is _no_ way to block the attacker. Everything you want to try to stop them is easily circumvented.... Remember, all he has to do is remove the HD, place it in a different system and boot to his own OS. Your HD is now his to do with what he wishes and his wishes probably don't equal your dreams.....
