Designing Security in a Wireless Network Using 802.1x

It has been difficult to prevent unauthorized connections to a MCSA Certification wireless network, even after taking every security precaution in configuring it. Anyone able to connect to your wireless network can detect and receive every data in the network. This also occurs in a wired network. Even the WEP encrypted data can also be successfully attached. Network security has been a problem to all connections especially the wireless network security. An attacker can from outside can connect to your facilities, causing disruptions to the network, infect the network, access and steal data and go without a trace. 802.1x can provide solutions to such problems if it is properly implemented, maintained and managed.

How 802.1x improves wireless network security

802.1x is a standard in IETF (Internet Engineering Task Force) that was created in order to address security issues of 802.11 standards. 802.1x is not a replacement of the other, but it is a security addendum of 802.11. 802.1x adds a considerable support of security to 802.11 wireless networks, although software and hardware upgrades are necessary since they are changes to wireless free Microsoft tests practice and infrastructure support. Changes in security come with additional authentication improvements, revocation and validation checking procedural changes and the key management. A Radius server is needed to perform authentication thus can provide improvements in authorization and auditing.

This is because IAS (Authentication Improvements Microsoft Internet Authentication Services) may be used as the Radius server. The flexibility in both computer and user authentication is added by the ability to use EAP types (Extensible Authentication Protocol). These include the PEAP-EAP-MSCHAPv2 Protected Extensible Authentication Protocol (PEAP) EAP-MSCHAPv2 and passwords being protected by Transport Layer Security (TLS). Mutual authentication to a wireless network is provided since the server is also authenticated by the client. This provides an ideal wireless network security.
