Notes on Security when Using Wireless LANs

(Important information on customer rights (maintaining privacy))
Because wireless LANs use electromagnetic signals instead of a LAN
cable 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 within a certain range, the electromagnetic
signals can pass through barriers such as walls, so that if security
countermeasures are not implemented in some way, problems such as the
following may occur.
• Communicated data can be intercepted
A third party may be able to receive wireless transmissions without
authorisation, and they could obtain personal information from these
transmissions such as IDs, passwords or credit card numbers, or they
could intercept the contents of personal e-mail messages.
• Unauthorised access to the network
A third party could access an individual or intra-company network
without permission and carry out any of the following activities.
• Retrieve personal data or other secret information (information
leakage)
• Pose as another user and send inappropriate data (impersonation)
• Overwrite the contents of intercepted data and resend it (falsification)
• Introduce a computer virus which could cause data loss or system
crashes (damage)
Initially, the possibility that such problems could occur through settings
concerning the security of the wireless LAN product and by using the
product are decreased, because the wireless LAN card and the access
point have security measures to deal with these problems.
For the wireless LAN equipment, settings concerning security may not be
set at the time of purchase.
Therefore, to decrease the possibility of security risks occurring, make
sure you follow the instructions in this manual to make the security
settings before using the wireless LAN card and wireless LAN access
point.
Make sure you understand these security settings fully before using
because the security setup can sometimes be bypassed by using a special
method of the wireless LAN specifications.
Security settings for this product, see s"Wireless LAN Security
Countermeasures" p.43
Contact the information centre for help making the security settings.
We recommend that you use this product after making security settings
using your own judgment and assuming full responsibility, and with your
full understanding of problems that may occur if you do not make any
security settings.
