Overview of WLAN-Fat AP Security
This section describes the definition and Purpose of WLAN Security.
Definition
WLAN security involves the following:
- User access security: Link authentication, access authentication, and data encryption are used to ensure validity and security of user access on wireless networks.
- Service security: This feature protects service data of authorized user from being intercepted by unauthorized users during transmission.
Purpose
WLAN networks are easy to deploy and expand, flexible, and cost-effective. As WLAN technology uses radio signals to transmit service data, service data can easily be intercepted or tampered by attackers when being transmitted on the open wireless channels. Security has become a major factor that hinders WLAN technology development.
WLAN technology can provide the following mechanisms to guarantee data security for wireless users:
- Security policies for wireless users, including link authentication, access authentication, and data encryption
