Wireless LAN Security Countermeasures
One of the advantages of using a wireless LAN is that it is possible to
communicate easily if you are within the range of the electromagnetic
waves, because with a wireless LAN data is exchanged through
electromagnetic waves.
On the other hand, since electromagnetic waves extend through
obstacles such as walls, the content of the communication can be
intercepted, and the network can be breached without using any
special tools if security is not set.
To prevent these problems, the following security functions have been
provided.
• Data encryption
Encode and transmit data. Even if data is intercepted, it cannot be
deciphered.
• Connection limitation (Authentication)
A users name and a password are registered in advance, which means
that only the registered wireless port can connect to the network and
prevents unauthorized third parties from connecting to the network.
• Firewall
Prevents unauthorized computer access by closing ports that are not
used.
The security functions that can be used with this projector vary
depending on the connection mode of the wireless LAN.
Use the firewall function provided with your OS.
* Only effective when the access point for the connection destination support
the same function.
