Security Countermeasures for Wireless LAN
Because wireless LANs use radio signals to send and receive data, they have
the advantage of allowing a device to connect to the network easily as long as
they are within range to receive the signals.
A disadvantage of this is that the radio signals can pass through barriers such
as walls, so that if security countermeasures are not implemented in some way,
transmissions can be intercepted and outsiders can get unauthorised access to
the network even without using special tools.
The following security functions are provided in order to solve such problems.
• Data encryption
Data is encrypted before it is transmitted. Even if data is intercepted, it
cannot be opened and viewed.
• Connection limitations (authentication)
A username and password are registered beforehand so that only registered
wireless LAN terminals can connect to the network, in order to prevent
unauthorised third parties from connecting to the network.
•Firewall
Prevent unauthorized access from outside of the LAN by blocking off
unused ports.
The security functions used by this projector vary depending on the mode used
to connect to the wireless LAN.
*1 This can only be used when connecting using a computer that is running
Windows XP.
*2 Only valid if the access point being connected to supports the same
functions.
*3 If using EMP NS Connection on a Macintosh, WPA is not supported.
