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 standard.
