    ok, i have a BIOS password set on my laptop, with no windows password, simply so i can boot, enter the password, and leave (unless i want to boot to linux, which involves selecting linux at the bootloader, then entering the password at linux, lol).

    so im just wondering what you guys use, and what the merits of one over the other are!

    well Bios passwords are handy, but they can be circumvented in under 5 minutes on most machines

    they do however stop people booting say, a knoppix CD and accessing files you might not want them accessing

    Windows passwords should be a requirement for any machine on a network, simply because network services and such are accessed with that password, so a blank one puts the machine at considerable risk

    I dont actually have a 'bios system' password, just a 'bios' password

    this means a password is required to enter the bios, but not boot the machine

    I also use EFS and PGP

    Hi All

    Depends on what type of security you are looking for. BIOS gives physical security in that to sit at the machine you need to logon to the hardware. OS gives logical security in that if you want to log onto the machine that is connected to a network or the Internet you need a user name and password.

    At work and home I have an OS password as you need keys to get into the buildings so that is my physical security:!:

    Fergal, as Phoenix pointed out the BIOS password can be circumvented in about 5 minutes through default backdoors the manufacturers include. All it needs is someone to sit there at the machine and surf the net for a list of the default passwords, 5 minutes later they are in.

    However in saying that if a bad guy gets to sit at your machine, it's not yours anymore.

    OS passwords for me, Phoenix made a point about network services and such that are accessed with the admin password, so a blank one puts the machine at considerable risk and I would have to second that point too. If your running your PC with a blank password and you have admin privileges your leaving the door open to all manner of nasty consequences.

    Nope, she sholdn't be able to delete anything important, just her own files that she has created. I don't think she is able to install anything either, so you may have to install anything she wants to use through your account, and then give her access.

    OS password for me - my theory being that w2k/XP is tight enough if applied properly. I've never bothered with the BIOS to honest (just one more to forget after all)

    Must say, I'm proud of my 6 year old daughters ability to use her password responsibly on her PC (I'm not that Victorian a Dad before you all start hollering - her account has a p/w solely because you need to have one to RDP into her machine).

    An interesting quandary arose this weekend though, when she asked me what my password was. Hmmm, what do you do then ??? :hhhmmm

    id just point out that everyone is supposed to have their own password, and that they arent supposed to tell anyone what it is, its their own secret!

    or i spose you could just point out that its best that she doesnt know it, so that she cant accidentally break the pc. that way, she understands that her account wont let her break it, and that if she knew your p/w then it might cause harm to the pc!

    Huh coward


    you tell her to keep her nose out or else :twisted:

    My kids have got their own machine that they are administrators on but on my pc they are users with very limited rights :dry

    They both have their own p/w I have mine and then there's the admin, and no-one knows that one except ME :biggrin
