In this chapter, you learned how remote access to your network presents an inherent security risk and how Windows Server 2003 provides mechanisms to make remote access more secure. Remote access can be controlled through the use of remote access policies and centralized RADIUS servers, and dial-up access can be made more secure by selecting appropriate authentication and encryption protocols. Understanding how VPNs work allows you to design a VPN solution to provide maximum security.
It is important to remember that no security is absolute. This is especially true when talking about allowing remote users to access your network. There is simply no attacker-proof way to allow access. However, many different security options help you lessen the risks. You should carefully weigh the risks of allowing remote access against the benefits before you provide remote access in your environment.
