Glossary 925
on a network. Every computer in a TCP/IP network has its own IP address
that is either dynamically assigned at startup or permanently assigned. All
TCP/IP messages contain the address of the destination network as well as
the address of the destination station. This enables TCP/IP messages to be
transmitted to multiple networks (subnets) within an organization or
worldwide.
TLS
(Transport Layer Security) provide privacy and data integrity between two
communicating applications.
Virtual AP
An instance of a unique virtual access point.
VPN*
A type of technology designed to increase the security of information
transferred over the Internet. VPN can work with either wired or wireless
networks, as well as with dial-up connections over POTS. VPN creates a
private encrypted tunnel from the end user's computer, through the local
wireless network, through the Internet, all the way to the corporate servers
and database.
WAN*
A communication system of connecting PCs and other computing devices
across a large local, regional, national or international geographic area. Also
used to distinguish between phone-based data networks and Wi-Fi. Phone
networks are considered WANs and Wi-Fi networks are considered Wireless
Local Area Networks (Wireless LANs).
War Driver
A program or utility used to discover and gain unauthorized access to wireless
access points in order to corrupt or collect information stored on the network.
WEP*
Basic wireless security provided by Wi-Fi. In some instances, WEP may be all
a home or small-business user needs to protect wireless data. WEP is
available in 40-bit (also called 64-bit), or in 108-bit (also called 128-bit)
encryption modes. As 108-bit encryption provides a longer algorithm that
takes longer to decode, it can provide better security than basic 40-bit (64-bit)
encryption.
