Configuring WPA2 Personal on Cisco 5508 Wireless LAN Controller: Next we will see how to Configure WPA2 Personal and WPA2 Enterprise on a Cisco WLAN Controller and also directly on Access Point devices. Moreover, if you use the widely used EAP-PEAP authentication protocol, you will need to install a trusted Digital Certificate on the RADIUS server.Ī very common scenario with Enterprises that have a Microsoft Active Directory server installed, is to integrate the RADIUS server with the Microsoft AD in order to provide user authentication via the AD user directory. You need an External RADIUS server in order to configure WPA2 Enterprise. An 802.1x EAP-based authentication method must be used to authenticate the clients. WPA2 Enterprise : This is the most secure mode of operation and – as the name suggests – it is mostly used in Enterprise networks. This is still very secure provided that the pre-shared key remains strictly private within the users of the WiFi network and also provided that the key has sufficient length more than 8-10 characters including alphanumeric and special characters. WPA2 Personal : A pre-shared key is used to authenticate clients on the WLAN and this is the most applicable mode for home use or for small WiFi networks. These are WPA2 Personal and WPA2 Enterprise. WPA2 supports two modes of operation depending on the environment which is implemented and the level of security you want to provide. This means that every packet that is sent over the air is encrypted with a unique key. The encryption keys that are used for each client on the network are unique and specific to that client. It provides layer 2 based security and uses IEEE 802.1x port based authentication protocol.ĮDIT: The newest WPA3 is currently the most secure protocol for WLAN protection.Ĭompared to the older Wi-Fi security standards, WPA2 is much more secure than WPA and WEP because it uses the much stronger Advanced Encryption Standard (AES) together with some other key exchange, authentication and ciphering algorithms.įor example, WPA2 creates new session keys on every association. WPA2 is currently considered as the most secure method to protect a Wi-Fi network. WPA2 is a security protocol framework that is used to protect wireless networks. WPA2 is short for Wi-Fi Protected Access 2 and is standardized under the IEEE 802.11i standard.
