Microsoft has revealed at a security panel at CeBIT that it is preparing to dump passwords in favour of two-factor
authentication in forthcoming versions of Windows.
Detlef Eckert, the senior director in charge of Microsoft's Trustworthy Computing initiative, did not specify
which form of two-factor authentication would be used in the next edition of the company's operating system,
codenamed Longhorn
Acknowledging that in this day and age single factor authentication, in other words PASSWORDS, just aren't enough to
secure corporate IT assets, Microsoft has announced much tighter integration of two factor authentication technologies
into future versions of the Windows OS. While they do exist today, two factor auth is more of an add on to the OS
than a core component, as a result, it is inherently not as secure as it could be.
One well known Online Financial Services
provider has already begun to head down this route. Who might you ask?
E*Trade.
For those of you unfamiliar with two factor authentication schemes, they can be summarized as
authentication with two pieces of information. Typically these pieces of information amount
to SOMETHING YOU KNOW and SOMETHING YOU HAVE. There are many examples. In the case of
RSA SecureID the "something you know" is a PIN number and the "something you
have" is a key fob with a code that changes every sixty seconds based on an algorithm that the authentication server
knows based on the serial number of the fob and the time. If you lose the device, the PIN is useless and if you
lose or forget the PIN, the device is useless.
Other approaches use RFID tags such that if the tag is in proximity to a sensor and the proper PIN is entered, the
machine will unlock and when the sensor leaves the area, the machine will lock. Another well known approach to two
factor authentication uses biometrics (a thumb/finger print, retina scan, etc…) and a PIN code. Again, if
you lose the bio feature…well, you've got bigger problems then not accessing your computer systems unless of your name
is Jack Bauer.
Two factors. Very secure.
