IANA

See Internet Assigned Number Authority (IANA).

ICMP

See Internet Control Message Protocol (ICMP).

IIS

See Internet Information Services (IIS).

inbound access

The ability to send information from an external network, such as the Internet, to an internal or external network.

Integrated authentication

A secure form of authentication, where the user name and password are hashed before being sent across the network. Users are authenticated by using either the Kerberos V5 authentication protocol, the NTLM authentication protocol, or a challenge/response authentication protocol. See also Basic authentication, Digest authentication, and Advanced Digest authentication.

Integrated Services Digital Network (ISDN)

A dial-up connection to the Internet installed by your Internet service provider (ISP) or telephone company. An ISDN line can offer speeds up to 128,000 bits per second (bps) and must be installed at both the server site and the remote site.

interactive application

A program written in C, Perl, or as a Windows batch file. The user initiates the program by clicking a link in a hypertext document.

Internet Assigned Number Authority (IANA)

A regulatory organization that is responsible for the assignment and registration of the values of unique parameters for Internet protocols. These values include top-level domain names, IP addresses, port numbers, protocol and enterprise numbers, content types, content subtypes, character sets, and access types.

Internet Control Message Protocol (ICMP)

The Internet standard protocol subset of IP that handles control and error messages. Gateways use ICMP to send problem reports on packets back to the source that sent the packet.

Internet Information Services (IIS)

The Microsoft® Internet server feature designed for implementing and managing Web sites. Although IIS supports multiple protocols, it primarily transmits information in HTML pages by using HTTP. Forefront TMG integrates fully with IIS.

Internet Protocol (IP)

The Internet standard routing protocol that defines the IP datagram as the unit of data transfer and provides the IP address scheme to route packets from one network location to another. IP includes the ICMP protocol. The Internet Protocol suite is often called Transmission Control Protocol/Internet Protocol (TCP/IP).

Internet Protocol security (IPsec)

A set of standards that are used to implement virtual private networks (VPNs). IPsec supports a tunnel mode, in which both the packet header and the payload are encrypted.

I/O completion port

A Windows construct that efficiently manages threads used for asynchronous input/output (I/O). An I/O completion port is created by the operating system at the request of the Forefront TMG.
