3DES A version of DES, also called “Triple DES” (TDES), in which three encryption
phases are applied. For more information, see NIST Special Publication 800-
67 at http://csrc.nist.gov/publications/nistpubs/800-67/SP800-67.pdf.
802.1 The standard for managing LANs and MANs. It is concerned with network
architecture, bridging, management, link security, and protocol layers above
the MAC and LLC layers. For more information, see IEEE 802.1 at http://
www.ieee802.org/1/.
802.11 The standard for wireless LANs. For more information, see IEEE 802.11 at
http://standards.ieee.org/getieee802/802.11.html.
802.11a A version of 802.11 that broadcasts at 5 GHz and provides a maximum speed
of 54 Mbps.
802.11b A version of 802.11 that broadcasts at 2.4 GHz and provides a maximum speed
of 11 Mbps.
802.11g A version of 802.11 that broadcasts at 2.4 GHz and provides a maximum speed
of 54 Mbps.
802.11i The enhanced security standard for 802.11, which supersedes WEP security.
For more information, see the standard at http://standards.ieee.org/
getieee802/download/802.11i-2004.pdf.
802.1X A port-based authentication standard for 802.1. 802.1X forces endpoints to
authenticate, establishing a point-to-point connection if authentication suc-
ceeds or blocking the connection if authentication fails. By basing authenti-
cation on secure EAP methods, 802.1X authentication can prevent
eavesdroppers from reading intercepted messages. The 802.1X standard
requires three components: the supplicant, which runs on the endpoint device;
the authenticator, which is typically a switch or AP; and the authentication server,
which is usually a RADIUS server. For more information, see IEEE 802.1X at
