Security Warnings Regarding the Use of Wireless LAN
Products
A Wireless LAN enables you to exchange information between devices (such as
computers) and wireless access points using radio waves, instead of a physical
LAN cable. You are advised that unauthorized access could be possible and
security features should be configured as appropriate. (See "Security Settings,"
on p. 2-10 for information on selecting encryption and authentication methods.)
On the other hand, as radio waves penetrate to all areas within a certain radius and
go through obstacles (such as walls), the following problems can occur if security
settings are not specified.
•
Transmitted data can be eavesdropped on
Third parties with malicious intent can deliberately intercept the radio waves and
possibly steal the following information:
- Personal information such as IDs, passwords, or credit card numbers.
- E-mail content
•
Unauthorized infiltration
Third parties with malicious intent can access a personal or corporate network
without authorization, and possibly perform the following:
- Extract personal or confidential information (information leakage)
- Impersonate a specific individual to perform communication or send out
misleading information (impersonation)
- Overwrite and resend intercepted information (modification)
- Send a computer virus, etc., to destroy data or systems (destruction)
Wireless LAN cards and wireless access points have security features to deal with
these problems. Therefore the possibility of such problems can be reduced by
specifying the security settings of the wireless LAN product.
The customer must understand the problems that may occur if security settings are
not specified and take responsibility for decisions regarding security. It is
recommended you specify security settings when using this product.
