Pretty Good Privacy (PGP) Pretty Good Privacy (PGP) is a computer program that provides cryptographic privacy and authentication. PGP is often used for signing, encrypting and decrypting e-mails to increase the security of e-mail communications. It was originally created by Philip Zimmermann in 1991.
Remote Access Client One of the ways in which a company can improve its productivity is by using Windows 2000 Routing and Remote Access service When clients are located off campus, this service can provide them with remote access to resources on the internal network and help maximize speed and security.
TCP/IP The TCP/IP suite of protocols is the set of protocols used to communicate across the internet. It is also widely used on many organizational networks due to its flexiblity and wide array of functionality provided.
Point to Point Tunneling Protocol (PPTP) Point-to-Point Tunneling Protocol (RFC 2637) works at the link layer. No encryption or key management included in specifications. A VPN tunneling Protocol used to send secure communications from point to point. It is used to access a network through the network using the speed of a modem. It uses PPP encryption or Microsoft Point to Point Encryption (MPPE) over TCP as a transport protocol. This means that PPP packets are encrpted, then placed in TCP packets and sent over the internet. On the other side, the information is unwrapped and decrypted and sent on as PPP. Therefore the same protocols supported by PPP are supported with PPTP (AppleTalk, IPX, TCP/IP, and NetBEUI). PPTP Installation is done with the Routing and Remote Access Administration Tool.
Point to Point Protocol (PPP) Point to Point Protocol is a form of serial line data encapsulation that is an improvement over SLIP which provides serial bi-directional communication. Packets are delivered in the order they were sent. It is much like SLIP but can support AppleTalk, IPX, TCP/IP, and NetBEUI along with TCP/IP which is supported by SLIP. It can negociate connection parameters such as speed, transport protocol, and selection of PAP or CHAP user authentication method.
RAS Remote Access Services (RAS) refers to any combination of hardware and software to enable the remote access to tools or information that typically reside on a network of IT devices.
VPN A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or individual users with secure access to their organization's network.
VPN (Virtual private network) is a computer network in which the links between nodes are formed over logical connections or virtual circuits between hosts of a larger network, such as the Internet.
ASP file Your ASP file will invariably be a mixture of text, ASP, and HTML tags.
URL Abbreviation of Uniform Resource Locator, the global address of documents and other resources on the World Wide Web. The first part of the address is called a protocol identifier and it indicates what protocol to use, and the second part is called a resource name and it specifies the IP address or the domain name where the resource is located. The protocol identifier and the resource name are separated by a colon and two forward slashes. For example, the two URLs below point to two different files at the domain The first specifies an executable file that should be fetched using the FTP protocol; the second specifies a Web page that should be fetched using the HTTP protocol:
