t
’s range to
another without losing the connection.
Router
An Internet device that routes requests for information to other routers until the
information’s location is found and the data can be transmitted back to the
origin of the request.
SPI
SPI is an acronym for Stateful Packet Inspection. The SPI engine examines
not just the headers of the packet, but also the packet contents, it can then
determine more about the packet than just its source and destination
information. Moreover, stateful inspection firewalls also close off ports until a
connection to the specific port is requested.
TCP/IP
Short for Transmission Control Protocol and Internet Protocol, the suite of
communications protocols that enable hosts on the Internet to connect and
exchange streams of data.
VPN
VPN is an acronym for Virtual Private Network. Via access control and
encryption, VPN brings the same security to data transmission through the
Internet as if it being transmitted through a private network. It not only takes
advantage of economies of scale but also ensures high level security while the
packet is sent over the large public network.
Wide Area Network (WAN)
A system of LANs being connected by telephone lines and radio waves.
Although someWANs may be privately owned, they are usually considered a
means of public access.
WEP
An acronym for
Wired Equivalent Privacy
. It is an encryption mechanism
used to protect your wireless data communications. WEP uses a combination
of 64-bit/128-bit keys to encrypt data that is transmitted between all points in a
wireless network to insure data security. It is described in the IEEE 802.11
