Glossary

Ethernet: Can refer to the IEEE 802.3 signaling protocol, or an Ethernet controller (also known as a Media Access Controller or MAC).

external interface: The FortiGate interface that connects to the Internet.

FTP, File Transfer Protocol: A protocol used to transfer files between computers that have different operating systems.

gateway: A combination of hardware and layer-3 (network-layer) software that relays packets from one network to another.

hash algorithm: A procedure that renders a text message as a unique number.

header: The part of a packet that includes the source and destination address of the associated data. This addressing information is used to route packets.

hop: The segment of packet transmission that occurs between two routers. A packet may make several hops as it travels to its destination.

host: A network entity that has an IP address.

HTTP, Hypertext Transmission Protocol: The protocol used by the World Wide Web. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands.

HTTPS: The secure HTML protocol for transmitting encrypted information to web servers using SSL. See also SSL.

hub: A device where communication links are brought together to exchange data between several computers.

ICMP, Internet Control Message Protocol: An IP message control protocol that supports error messages, test packets, and information messages related to IP. This protocol is used by the ping generator to send ICMP echo requests to a host.

IKE, Internet Key Exchange: A method of automatically exchanging IPSec authentication and encryption keys between two secure servers.

IMAP, Internet Message Access Protocol: An Internet email protocol that allows access to an email server from any IMAP-compatible browser.

internal interface: The FortiGate interface that connects to an internal (private) network.

Internet: The network that encompasses the world. As a generic term, it refers to any collection of interdependent networks.

IP, Internet Protocol: The component of TCP/IP that handles routing.

IP address: The point of attachment to a TCP/IP network. An IP address is a 32-bit quantity written in dotted decimal notation (four numbers separated by periods). See also netmask.

IPSec, Internet Protocol Security: A set of protocols that support secure exchange of packets at the IP layer. IPSec is most often used to support VPNs. See VPN.

ISP, Internet Service Provider: A company that provides customers with access to the Internet.

KB, kilobyte: A unit of storage (1 024 bytes).

L2TP, Layer 2 Tunneling Protocol: A security protocol that enables ISPs to establish VPN tunnels on behalf of dialup clients.

LAN, Local Area Network: A computer network that spans a relatively small area.

Layer 2: The data-link layer of the OSI model. Layer 2 is responsible for transmission, framing, and error control over a single link.

Layer 3: The network layer of the OSI model. Layer 3 is responsible for examining each network packet and sending them to the proper destination over the Internet.

local: The near end point (an IP address or port number) of a connection.

MAC address, Media Access Control address: A layer-2 hardware address that uniquely identifies a network node.

main mode: A way to hide the identities of VPN peers from passive eavesdroppers during IPSec phase 1 negotiations. See also aggressive mode.

MB, Megabyte: A unit of storage (1 048 576 bytes).

MIB, Management Information Base: A database of objects that can be monitored by an SNMP network manager.

modem: A device that converts digital signals into analog signals and back again for transmission over telephone lines.
