A Wireless LAN uses radio waves instead of cables to send and receive data. Because radio waves usually pass through walls and other obstructions, the following problems may arise if you do not configure wireless security settings.
Information leakage
Information such as IDs, passwords, credit card numbers, and e-mail content may be seen by an unauthorized 3rd party.
Unauthorized network access
Damage to or alteration of data and/or system configurations by viruses or other malware.
Impersonation of legitimate network users, resulting in data theft.
Theft of sensitive or confidential data.
To minimize the possibility of these threats, it is recommended that you check the available features of this printer, wireless access points, and other equipment that uses the Wireless LAN, and configure security settings for the Wireless LAN.
