4.2.6 Authentication and encryption
Wireless security is a complex and developing topic. This page gives a brief
overview of the basics involved in making a wireless network secure.
In the simplest terms, wireless security involves two strategies: authentication and
encryption.
A wireless security method, such as
WEP or WPA , involves varying levels of
authentication and encryption.
Authentication
Definition
Authentication verifies the identity of a user or device before granting access to a
network, making it more difficult for unauthorized users to access network
resources.
In order to be authenticated and allowed to use a network, a device must supply a
known password to other devices on the network. If the device cannot supply the
correct password, then it will not be able to use other devices on the network.
Types of authentication
The printer supports three types of authentication. Each type of authentication has
its benefits and limitations.
