DWS-1008 User's Manual
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) commandline 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 MobileLAN 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
DWL-8220AP 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 and does not disrupt
service.
roaming
The ability of a wireless user (client) to maintain network access when moving between
access points (APs).
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.
