R
RADIUS (Remote Authentication Dial-In User Service) - An authentication and accounting
system that verifies users' credentials and grants access to requested resources.
RC4 - An encryption algorithm designed at RSA Laboratories; specifically, a stream
cipher of pseudo-random bytes that is used in WEP encryption.
Rogue - A rogue station is one that you have not authorized for operation. Rogue stations,
particularly Access Points, often do not conform to WLAN security policies, which
enables an open, insecure interface to an organization's network from outside the
physically controlled facility.
Role - A role is a collection of network usage policies that you define to specify which
network resources and destinations in the enterprise a user may access, the bandwidth he
or she may use, and whether a secure tunneling protocol such as IPSec or PPTP is
required for the user connection.
RSSI - Received Signal Strength Indication.
S
Shared key - An encryption key known only to the receiver and sender of data.
SIP (Session Initiation Protocol) - A text-based signaling protocol, similar to HTTP and
SMTP, for initiating interactive communication sessions between users. Such sessions
include voice, video, chat, interactive games, and virtual reality.
SNMP (Simple Network Management Protocol) - You can run an SNMPv2 or SNMPv3
agent on the BSC to allow you to manage the BSC remotely using standard SNMP
applications such as HP OpenView.
SSID - Service Set Identifier. An SSID unique identifies a session between an Access Point
and a wireless PC Card. The SSID is attached to each packet of data transmitted between
the Access Point and client. The SSID is considered a WLAN's name.
SSL (Secure Sockets Layer) - A protocol that provides encrypted communications on the
Internet. SSL is layered beneath application protocols such as HTTP, SMTP, and Telnet,
and is layered above the connection protocol TCP/IP. SSL is used by the HTTPS access
method.
T
Termination VLAN - Termination VLANs on the BSC receive 802.1q-tagged packets from
the managed side and forward them with no tag to the protected side. This causes all
traffic for the VLAN to terminate on the managed side of the BSC.
TTLS - (Tunneled Transport Layer Security protocol) - Protocol providing secure encryption
and authentication for wireless clients.
W
WEP (Wired Equivalent Privacy) - A security standard established for wireless LAN
technology. It has proved less secure than initially believed.
V
VLAN (Virtual Local Area Network) - A logical grouping of two or more nodes which are
not necessarily on the same physical network segment but which share the same IP
Termination VLAN
Pass-through VLAN
network number. See also
