Security Information
Make sure that no unauthorized user logs on to the Wireless LAN and that no one
has access to the Internet or network resources.
Your print server offers several security mechanisms. The following table gives an
overview of different encryption and authentication methods.
*WPA/WPA2 is available from hardware version 2.0 onwards.
WEP (Wired Equivalent Privacy)
WEP is an encryption method according to IEEE 802.11 on the basis of the RC4
encryption algorithm. WEP offers mechanisms for data encryption and
authentication. WEP uses a key to encrypt the entire communication. For this
purpose, a key is stored in each WLAN device. WEP offers three modes.
- 'Open System' for data encryption. The Wireless LAN is available for all clients.
No authentication is carried out.
- 'Open System + EAP' for data encryption. In addition a version of the
'Extensible Authentication Protocol' is used for authentication purposes.
- 'Shared Key' for data encryption. In addition the Challenge-Response
authentication mechanism is used with a secret key.
