I am looking to implement a more advanced secure authentication of users who will have access to our internal business web systems.
We are using sessions, htaccess restricted IP and we also want to restrict the access unless the pc has the client side authentication. A lot of banks use this method and the certificate is installed in the "Tools", "Internet Options", "Content", "Certificates".
This will heighten the security of our system and who has access.
Can anyone help?
