management
for
computers
to
connect
and
use
a
network
service.
Because
of
its
broad
support
and
ubiquitous
nature,
the
RADIUS
protocol
is
often
used
by
ISPs
and
enterprises
to
manage
access
to
the
Internet
or
internal
networks,
WLANs,
and
integrated
e
‐
services.
Service
Set
Identifier
(SSID)
Name
of
a
WLAN.
All
wireless
devices
on
a
WLAN
must
use
the
same
SSID
to
communicate
with
each
other.
Simple
Network
Management
Protocol
(SNMP)
An
Internet
‐
standard
protocol
for
managing
devices
on
IP
networks.
Snooping
Passively
watching
a
network
for
data,
such
as
passwords,
that
can
be
used
to
benefit
a
hacker.
Temporal
Key
Integrity
Protocol
(TKIP)
An
encryption
protocol
that
uses
128
‐
bit
keys.
Keys
are
dynamically
generated
and
distributed
by
the
authentication
server.
TKIP
regularly
changes
and
rotates
encryption
keys,
with
an
encryption
key
never
being
used
twice.
Transmission
Control
Protocol/Internet
Protocol
(TCP/IP)
A
protocol
that
allows
communications
over
and
between
networks.
TCP/IP
is
the
basis
for
Internet
communications.
Weighted
Fair
Queuing
(WFQ)
WFQ
services
queues
are
based
on
priority
and
queue
weight.
Queues
with
larger
weights
get
more
service
than
queues
with
smaller
weights.
This
highly
efficient
queuing
mechanism
divides
available
bandwidth
across
different
traffic
queues.
Wired
Equivalent
Privacy
(WEP)
Security
protocol
that
provides
a
WLAN
with
a
level
of
security
and
privacy
comparable
to
that
of
a
wired
LAN.
WEP
encrypts
data
sent
between
wired
and
WLANs
to
keep
transmissions
private.
Wireless
Local
‐
Area
Network
(WLAN)
WLANs
use
RF
technology
to
send
and
receive
data
wirelessly
in
a
certain
area.
This
lets
users
in
a
small
zone
send
data
and
share
resources
such
as
printers
without
using
cables
to
physically
connect
each
computer.
Wi
‐
Fi
Protected
Access
(WPA
)
A
subset
of
the
IEEE
802.11i
standard.
WPA
applies
IEEE
802.1x
and
Extensible
Authentication
Protocol
(EAP)
to
authenticate
wireless
clients
using
an
external
RADIUS
database.
WPA
uses
Temporal
Key
Integrity
Protocol
(TKIP),
Message
Integrity
Check
(MIC),
and
IEEE
802.1x
to
encrypt
data.
See
also
WPA
‐
PSK
(WPA
‐
Pre
‐
Shared
Key).
Wi
‐
Fi
MultiMedia
(WMM)
Part
of
the
IEEE
802.11e
QoS
enhancement
to
the
Wi
‐
Fi
standard
that
ensures
quality
of
service
for
multimedia
applications
in
WLANs.
Wireless
Client
Supplicants
Software
that
runs
on
an
operating
system,
instructing
the
wireless
client
how
to
use
WPA.
WPA
‐
Pre
‐
Shared
Key
(WPA
‐
PSK)
WPA
‐
PSK
requires
a
single
(identical)
password
entered
into
each
Access
Point,
wireless
gateway,
and
wireless
client.
A
client
is
granted
access
to
a
WLAN
if
the
passwords
match.
