Fortress ES-Series CLI Guide: Glossary
XIX
RADIUS
Remote Authentication Dial-In User Service—an authentication service design that
issues challenges to connecting users for their usernames and passwords and authenti-
cates their responses against a database of valid usernames and passwords; described
in RFC 2865.
RAM
Random Access Memory—data storage that permits data bytes to be accessed in ran-
dom order.
RF Radio Frequency
RFC
Request for Comments—a document proposing an Internet standard that has been
accepted by the IETF as potentially developing into an established Internet standard.
RSA SecurID® An authentication method created and owned by RSA Security.
RSN
Robust Security Network - the concept, introduced in the 802.11i amendment to the
IEEE 802.11 standard, of a wireless security network that allows only
RSNAs to be cre-
ated.
RSNA
Robust Security Network Association - in the IEEE 802.11i amendment, a wireless con-
nection between 802.11i entities established through the 802.11i 4-Way Handshake key
management scheme.
RRL
Resilient Radio Link—in Fortress Mesh Points, active wireless links that form along the
best available path between the bridging-enabled BSSs of networked Mesh Points. RRLs
provide fault-tolerant connections for Fortress’s self-healing wireless networks.
SCP
Secure Copy—a network protocol, based on SSH, for securely transferring files between
remote computers over public networks.
Secure Client Refer to Fortress Secure Client .
Secure Client device
In Fortress products, a device such as a laptop, PDA, tablet PC, or barcode scanner, that
has the Fortress Secure Client installed and configured to permit the device to commu-
nicate on the Fortress-secured network.
SFP Small Form Pluggable—shorthand for fiber optic Small Form Pluggable transceiver.
SHA
Secure Hash Algorithm, cryptographic hash functions developed by the NSA and pub-
lished by NIST in FIPS 180-2.
SHS
Secure Hash Standard—FIPS-approved NIST standard specifying five secure hash algo-
rithms: SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512.
SISO
Single-Input Single-Output—as distinguished from more recently developed radio oper-
ation.
SLIP
Serial Line Internet Protocol—a method for communicating over serial lines, developed
for dial-up connections.
SMTP
Simple Mail Transfer Protocol—describes a method for transmitting e-mail between
servers.
SNMP
Simple Network Management Protocol—a set of protocols for simplifying management
of complex networks. The SNMP server sends requests (PDUs) to network devices, and
SNMP-compliant devices (SNMP agents) respond with data about themselves (stored in
MIBs).
SNMP agent
Any network device running the SNMP daemon and storing a MIB, a client of the SNMP
server.
SSH®
Secure Shell®, sometimes, Secure Socket Shell—a protocol, developed by SSH Com-
munication Security®, for providing authenticated and encrypted logon, file transfer
and remote command execution over a network.
SSID Service Set Identifier—a unique name that identifies a particular wireless network
