Introduction

In this menu, you configure the security settings with which you want to operate

your SCALANCE W 788. Apart from selecting the authentication and encryption

scheme, this also includes the decision as to whether or not an external Radius

server is used and whether access is restricted based on MAC addresses (ACL).

6.4.1 Basic Wireless Menu Command

WEP

WEP (Wired Equivalence Privacy) is an optional part of the IEEE 802.11 standard.

WEP specifies methods of authentication and encryption working with fixed keys

stored on the device. All devices that want to access a network in which WEP is

used must first be supplied with the same keys. The keys can only be changed

manually.

WPA

WPA (Wi-Fi Protected Access) cancels out some of the disadvantages of WEP by

using dynamic key exchange. A string specified by the user simply serves as an

initial value for generating the keys. WPA is downwards compatible with WEP.

IEEE 802.1x (Radius)

The heart of the standard is the use of a Radius server as the authentication

server. In addition to this, in IEEE 802.1x, the entire communication is encrypted.
