How many types of authentication are there?
There are three basic types of authentication. The first is knowledge-based — something like a password or PIN code that only the identified user would know. The second is property-based, meaning the user possesses an access card, key, key fob or authorized device unique to them. The third is biologically based.
What is the purpose of remote user authentication?
Remote user authentication is a mechanism in which the remote server verifies the legitimacy of a user over an insecure communication channel.
Which authentication protocol should be used for smart card authentication?

Dial-in servers use the Point-to-Point Protocol (PPP) or in the case of some older servers, the Serial Line Internet Protocol (SLIP) as the link layer protocol. VPN servers can use the Point-to-Point Tunneling Protocol (PPTP), Layer 2 Tunneling Protocol (L2TP), or IPSec tunnel mode to establish a secure "tunnel" over the Internet. Windows remote access servers support the following set of authentication methods: 1 Password Authentication Protocol (PAP) 2 Challenge Handshake Authentication Protocol (CHAP) 3 Microsoft's implementation of CHAP (MS-CHAP) 4 Updated version of MS-CHAP (MS-CHAP2) 5 Extensible Authentication Protocol/Transport Layer Security (EAP/TLS)

Version 2 adds such features as mutual (two-way) authentication of both client and server, as well as stronger encryption keys. MS-CHAP v2 is more secure than CHAP for Windows systems.
Can you have multiple remote access servers on Windows 2003?
Windows 2003 Server Enterprise Edition's IAS implementation puts no limits on the number of RADIUS clients you can configure or on the number of RADIUS server groups you can have. Even more importantly, a single RADIUS server can support many remote access servers, so that as you add additional dial-in and/or VPN servers, their users are all still authenticated through one central point: the RADIUS server. The fact that the authentication server is separate from the access server (s) makes this both more secure and more scalable than other authentication methods.

What port does XTACACS use?
This protocol is also an application layer protocol and observes the client/server model. Since TACACS+ is also a well known protocol, it stands to reason that there is also a well known port associated with this activity, which is TCP Port 49. That being said, XTACACS uses UDP. There is always the exception to the rule!
What is a tacs?
Terminal Access Controller Access Control System , or TACACS, is similar to RADIUS and is used to regulate access to the network. One of the biggest differences between TACACS and RADIUS is that TACACS primarily uses TCP for its transport protocol needs vs. the UDP that RADIUS will use. There are also three versions of TACACS with TACACS+ being the most recent. It is important to note that TACACS+ is not backwards compatible with the other earlier versions. This protocol is also an application layer protocol and observes the client/server model. Since TACACS+ is also a well known protocol, it stands to reason that there is also a well known port associated with this activity, which is TCP Port 49. That being said, XTACACS uses UDP. There is always the exception to the rule!
