    19. Configuring Remote Desktop Settings Locally (cont.) • Network Level Authentication (NLA) – A reordering of the normal authentication process. Ordinarily, to authenticate to a server, you contact the server and then provide your credentials. In NLA, you provide your user name and password first. Only after that procedure is completed is the server contacted for authentication. Using Remote Desktop

    31. Virtual Private Networks • Virtual private network(VPN)– Private network established within a public network, most frequently the Internet. In an enterprise, it is most often used by users logging in from remote locations, such as their homes, to the enterprise domain through the Internet. Understanding and Configuring Virtual Private Networks

    32. Virtual Private Networks (cont.) • To emulate point-to-point links, VPNs encapsulate data in a package that contains a header with routing information and a payload of encrypted data. Understanding and Configuring Virtual Private Networks

    33. Virtual Private Networks (cont.) • From an implementation standpoint, there are three basic requirements for establishing a VPN. • User Authentication and Auditing • IP Address Assignment • Data Encryption Understanding and Configuring Virtual Private Networks
