There is a SE Linux related issue in this. In the future we will be supporting other methods of authentication. There are useful methods of authentication such as smart-cards which may have similar interfaces to the OS as useless things such as biometrics. We need to make sure that only certain applications can communicate with the authentication hardware, and the hardware in question may have multiple capabilities (think of a smart-card that authenticates the user and also has a GPG implementation). So we will probably need a user-space object manager to control access to the security hardware. Finally we need a trusted path so that a GPG card will only sign things when instructed by the user (not a trojan).
> Note that biometrics do *not* automagically make it more secure - in Remove the eye. ;) One big disadvantage of biometric systems is the risk of theft. Having keys or cards stolen is bad, having an eye or a finger stolen is really bad. -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page -- This message was distributed to subscribers of the selinux mailing list.
