You need a credential for authenticating yourself to a data processing equipment. This credential can be 'something you know' (password), 'something you have' (card, certificate) or 'something you are' (biometrics) - or better - a combination of this possibilities. Of course these variants are offering varying security levels.
Current Windows operating systems are Winlogon and the Graphical Identification and Authentication Modul (GINA) together the Logon to a computer and a domain. Configuration can be done by group policies in Active Directory. By default there is logon by passwords and logon by smart cards supported.

Is there, at start, a smart card reader discovered, Winlogon is triggering also pull and push events of a card, aside the Strg-Alt-Del combination, and is reporting this to the GINA. At Logon the GINA requesting the PIN for the card, to input it on the keyboard.
Smart Cards require an installed Smart Card CSP on the computer, which is the middleware to the smart card. There are several smart card CSPs included, but they are only for older smart cards.
The Logon can be flexible adapted, through exchange of the MS GINA (msgina.dll) with an own changed GINA. An installation for a small amount of users can be done using the integrated features, but if there are a great many of users to manage, a card management system
is highly recommended.

If you want to some research about the solutions, do this also in our knowledge base.
There you can find more about the basic concepts and functionality of the particular solutions, cryptographic basics
and instructions for configuration
and how you can successfully build these solutions into IT-Security Governance
framework.
