SSID
Each ESS has a Service Set Identifier (SSID) used to identify the Radio that belongs to the ESS. Radios
can be configured with the SSID of the ESS to which they should associate. By default, radios broadcast
their SSID to advertise their presence.
WEP
According to the IEEE 802.11 standard, Wired Equivalent Privacy (WEP) is intended to provide
“confidentiality that is subjectively equivalent to the confidentiality of a wired local area network medium
and that does not employ cryptographic techniques to enhance privacy.”
WEP relies on a secret key that is shared between a mobile station and an access point. WEP uses the
RC4 stream cipher invented by RSA Data Security. RC4 is a symmetric stream cipher that uses the same
variable length key for encryption and decryption. With WEP enabled, the sender encrypts the data frame
payload and replaces the original payload with the encrypted payload. The sender then forwards the
encrypted frame to its destination. The encrypted data frames are sent with the MAC header WEP bit set.
Thus, the receiver knows to use the shared WEP key to decrypt the payload and recover the original
frame. The new frame, with an unencrypted payload can then be passed to an upper layer protocol.
WEP keys can be either statically configured or dynamically generated. In either case, WEP has been
found to be easily broken.
WPA
Wi-Fi Protected Access (WPA) is a replacement security standard for WEP. It is a subset of the IEEE
802.11i standard being developed. WPA makes use of TKIP to deliver security superior to WEP. 802.1X
access control is still employed. The Authentication Server provides the material for creating the keys.
COFDM
COFDM involves modulating the data onto a large number of carriers using the OFDM technique. The
Key features which makes it work, in a manner is so well suited to terrestrial channels, includes:
• Orthogonality (the “O” of COFDM);
• The addition of Guard interval;
• The use of error coding (the “C” of COFDM), interleaving and channel-state information
COFDM is resistant to multipath effects because it uses multiple carriers to transmit the same signal.

RIP
The most popular of the TCP/IP interior routing protocols is the Routing Information Protocol (RIP). RIP is
used to dynamically exchange routing information. RIP routers broadcast their routing tables every 30
seconds by default. Other RIP equipments will listen for these RIP broadcasts and update their own route
tables.
DHCP
DHCP stands for ‘Dynamic Host Configuration Protocol’ and is a means for networked computers to get
their TCP/IP networking settings from a central server. Importantly, DHCP assigns IP addresses and
other TCP/IP configuration parameters automatically.
SNMP
Short for Simple Network Management Protocol, a set of protocols for managing complex networks. The
first versions of SNMP were developed in the early 80s. SNMP works by sending messages, called
protocol data units (PDUs), to different parts of a network. SNMP-compliant devices, called agents, store
data about themselves in Management Information Bases (MIB) and return this data to the SNMP
requesters.
SYSLOG
In order to track information on events, device jobs, and packets flows, most security devices out put
these events using the syslog information model.
