626 Glossary
registration authority (RA)
certificate and instructs the certificate authority (CA) to issue the certificate. Registration authorities are part of
a public-key infrastructure (PKI), which enables secure exchanges of information over a network. The digital
certificate contains a public key for encrypting and decrypting messages and digital signatures.
Remote Authentication Dial-In User Service
restricted access
command-line interface (CLI) commands required for viewing status information (show commands), except
those that list security information in clear text. Users with restricted access can clear ARP requests and ping
hosts. Compare enabled access.
RF detection sweep
Domain™ group, to locate rogue clients, rogue access ports, and ad hoc users. A sweep can be either a
scheduled sweep or a continuous SentrySweep™ search. During a scheduled sweep, each included Access
Point (AP) access point radio sweeps all channels in the IEEE 802.11b/g and 802.11a spectrum. In contrast,
SentrySweep operates only on the disabled radios in a Mobility Domain and does not disrupt service.
roaming
The ability of a wireless user (client) to maintain network access when moving between access
ports (APs).
robust security network
rogue access port
Rogue access ports subvert the security of an enterprise network by allowing potentially unchallenged access
to the enterprise network by any wireless user (client) in the physical vicinity.
rogue client
intercepting and modifying transmissions to circumvent the normal authorization and authentication
processes.
RSA
A public-key algorithm developed in 1977 by RSA Data Security, Inc., used for encryption, digital
signatures, and key exchange.
RSN
Robust security network. A secure wireless LAN (WLAN) based on the developing IEEE 802.11i
standard.
RSSI
Received signal strength indication. The received strength of an incoming radio frequency (RF) signal,
typically measured in decibels referred to 1 milliwatt (dBm).
scalability
performance.

Secure Shell protocol
Secure Sockets Layer protocol
