PCMCIA:
A hardware element generally used in laptop
computers for expanding their capacity. The
most common examples are wireless adap-
tors.
Ports:
Physical or logical connections for sending
and receiving data. Ports allows programmes
to communicate through the network.
SSID:
Code included in all the packages within a
wireless network to identify them as part of
that network. This allows the SSID to distin-
guish the different wireless networks availa-
ble.
TCP/IP:
Network protocols on which the Internet is
based and which enable data transmission
between computer networks.
WPA-PSK:
System for protecting wireless networks (Wi-
Fi); it was developed with the aim of com-
pensating the deficiencies in the previous
WEP system. WPA processes user authenti-
cation by means of a server which stores the
users' credentials and passwords. In order to
prevent the compulsory use of this server in
networks, WPA enables authentication via a
shared key ([PSK], Pre-Shared Key) which,
like WEP, requires the introduction of the
same key in all the systems within the net-
work.
WPS:
Standard promoted by the Wi-Fi Alliance
aimed at creating secure WLAN networks.
WPS is not a security mechanism per se, but
rather it involves the definition of several me-
chanisms to facilitate the configuration of a
secure WLAN network with WEP, WPA and
WPA2, designed to minimise user interven-
tion in small or home office (SOHO) environ-
ments. Specifically, WPS defines the mecha-
nisms whereby the different network devices
obtain the necessary credentials (SSID and
PSK) to initiate the authentication process.
