WAB–2000 Wireless Access Point
AES
The Advanced Encryption Standard (AES) was selected by National
Institute of Standards and Technology (NIST) in October 2000 as an up-
grade from the previous DES standard. AES uses a 128-bit block cipher
algorithm and encryption technique for protecting computerized infor-
mation.
The WAB–2000 uses AES for the bridging channel.
MAC Address Filtering
The MAC address, short for Media Access Control address, is a hard-
ware address that uniquely identifies each node of a network. In IEEE 802
networks, the Data Link Control (DLC) layer of the OSI Reference Model
is divided into two sub-layers: the Logical Link Control (LLC) layer and the
Media Access Control (MAC) layer. The MAC layer interfaces directly with
the network media. Consequently, each type of network media requires a
unique MAC address.
Authentication is the process of proving a client identity. The
WAB–2000 access points, if set up to use MAC address filtering, detect
an attempt to connect by a client and compare the client's MAC address
to those on a predefined MAC address filter list. Only client addresses
found on the list are allowed to associate. MAC addresses are pre-as-
signed by the manufacturer for each wireless card.
DHCP Server
The DHCP function is accessible only from the local LAN port to be
used for initial configuration.
Operator Authentication and Management
Authentication mechanisms are used to authenticate an operator ac-
cessing the device and to verify that the operator is authorized to assume
the requested role and perform services within that role.
Access to the management screens for the WAB–2000 requires knowl-
edge of the assigned operator ID and Password. The Factory defaults are:
• ID: crypto
• Password: officer
The Crypto Officer initially installs and configures the WAB–2000
after which the password should be changed from the default password.
The ID and Password are case sensitive.
