Notes on Security when Using Wireless LAN
Important informationoncustomer rights (maintaining privacy)
The advantage of using a wireless LAN over a LAN cable is that, because informationis
exchanged using radio signals, youcaneasily connectto the network if youare within range of
the radio signals. A disadvantage of this is thatwithin a certain range, the electromagnetic
signals canpass through barriers such as walls, so thatif security countermeasures are not
implemented in some way, problems such as the following may occur.
•Communicationdata canbe intercepted
A third party may be able to receive wireless transmissions without authorization, and they
could obtain personal informationfrom these transmissions such as IDs, passwords, or credit
card numbers, or they could interceptthe contents of personal e-mail messages.
•Unauthorized access to the network
A third party could access anindividual or intra-company network without permissionand
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 thatsuch problems could occur through settings concerning the
security of the wireless LAN productand by using the productare decreased, because the
wireless LAN card and the access point have security measures to deal with these problems.
We recommend thatyouuse this productafter making security settings using our own
judgement and assuming full responsibility, and with your full understanding of problems
thatmay occur if youdo notmake any security settings.
Notes on Setting SSID (Service Set Identifier)
For protectionof security, note the following precautions whensetting the SSID.
•Change the SSID from the defaultsetting.
•Donotsettexts by which the owner canbe identified as the SSID.
Notes on Setting Cryptographic Key
For protectionof security, note the following precautions whensetting the cryptographic key.
•Avoid using words ona dictionary as practicably as possible.
•Combine meaningless alphanumeric characters and symbols.
•Usetexts consisted of atleast13 characters or more or of 20 characters or more if possible.
