Security enabled by N22A
The wireless LAN installed in N22A has the following security features.
1. Preventing interception
Setting an encryption key by using the encryption feature allows wireless LAN data
among communication devices using the specific encryption key to be encrypted.
However, encryption keys may possibly be known by outsiders or decrypted by
decryption technology. Accordingly, it is recommended to change encryption keys
periodically.
For encryption feature settings, see
“
Setting encryption feature
”
of
“
Wireless LAN
”
in
this section.
2. Preventing illegal accesses by setting SSIDs (network names)
Setting specific SSIDs (network names) for both access points and communication
devices can avoid connections from communication devices without the same
SSIDs. However, SSIDs can be known by using devices which have the feature of
detecting SSIDs automatically.
To avoid this, SSID hiding must be set on access points not to notify them.
Registering MAC addresses of connected devices in each access point disables
devices not registered to connect to the access point (MAC address filtering). For
setting SSIDs, see
“
Setting encryption feature
”
