Appendix 2 Security
As it is difficult to define the communication area of a wireless LAN network because of the wireless (radio) characteristic,
the definition is likely to be vague. Depending on where the equipment is installed or how the office is constructed, the
network area may extend over to the outside of the site. This means that communication data leaks to the outside of the site,
and illegal access from outside the site is allowed. Even if the network area remains in the site, if visitors come into the site,
illegal access from the parking lot, information office, and toilet room may be allowed.
Therefore, it becomes important to enhance security to operate the wireless LAN network.
The following explains the points that are important for enhancing security.
· Network name (ESSID)
The network name (ESSID) is a group name that logically identifies the wireless LAN network. Because it is not a password
but an identifier, its security is not enhanced.
· Filtering by MAC address
Access from a wireless LAN station with an unknown MAC address can be denied.
· WEP
An encrypted network packet makes it difficult to illegally access the network and to decrypt communication contents.
Encryption processing deteriorates network throughput.
· 802.1X Function
Authenticating each station can prevent illegal access of the station. Also, changing and distributing the WEP key at regular
intervals makes interception difficult.
This function provides the highest security facility in this product.
· Communication area
After the equipment is installed, it is recommended to investigate the communication-enabled area by using the station.
