Understanding Security Issues on Wireless Networks
Wireless mediums are inherently less secure than wired mediums. For example, an
Ethernet NIC transmits its packets over a physical medium such as coaxial cable or
twisted pair. A wireless NIC broadcasts radio signals over the air allowing a wireless
LAN to be easily tapped without physical access or sophisticated equipment. A hacker
equipped with a laptop, a wireless NIC, and a bit of knowledge can easily attempt to
compromise your wireless network. One does not even need to be within normal range
of the access point. By using a sophisticated antenna on the client, a hacker may be
able to connect to the network from many miles away.
The D-Link DWL-2210AP provides a number of authentication and encryption schemes
to ensure that your wireless infrastructure is accessed only by the intended users. The
details of each security mode are described in the sections below.
