registration authority (RA) - Network software that verifies a user (client) request for a digital 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 - See RADIUS.
restricted access - Permission to use most Mobility System Software (MSS) 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 - A comprehensive search for radio frequency (RF) signals within a Mobility group,
to locate rogue clients, rogue access points, and ad hoc users. A sweep can be either a scheduled
sweep or a continuous SentrySweep™ search. During a scheduled sweep, each included Mobility
Point 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 network and does not disrupt service.
robust security network - See RSN.
rogue access point - An access point (AP) that is not authorized to operate within a wireless network.
Rogue access points 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 - A user (client) who is not recognized within a network, but who gains access to it by
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 - The ability to adapt easily to increased or decreased requirements without impairing
performance.
secure hashing algorithm - See SHA.
Secure Shell protocol - See SSH.
Secure Sockets Layer protocol - See SSL.
