GLOSSARY 697

roaming	The ability of a wireless user (client) to maintain network access when
	moving between access points (APs).
robust security	See RSN.
network
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	See SHA.
algorithm
Secure Shell protocol	See SSH.
Secure Sockets Layer	See SSL.
protocol
security ACL	Security access control list. An ordered list of rules to control access to
	and from a network by determining whether to forward or filter
	packets that are entering or exiting it. Associating a security ACL with a
	particular user, port, virtual LAN (VLAN), or virtual port on a Wireless
	Switch (WX) controls the network traffic to or from the user, port,
	VLAN, or virtual port. The rules in an ACL are known as access control
	entries (ACEs). See also ACE.
