Wireless LAN Security Countermeasures

32

 

 

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.
