Even if you have taken every security precaution in configuring your MCSA Certification(http://www.mcsa-70-270.com)
wireless network, it is difficult to prevent unauthorized connections. Anyone who can connect can detect and receive all data on that network and potentially on your wired network. Even WEP-encrypted data might be successfully attacked. An attacker can connect from outside your facilities, disrupt your network, infect it, steal data, and then be gone without a trace. 802. Ix can provide a solution to such problems if properly implemented and managed. This lesson will show you how to design a solution like this.
How 802.Ix Improves Wireless Security
802. Ix is an Internet Engineering Task Force (IETF) standard that was created to address the security issues of 802.11. 802.Ix is not a replacement for 802.11; instead, think of 802.Ix as the security addendum for 802.11. 802.Ix does add considerable security support to 802.11 wireless networks; however, hardware and software upgrades are necessary, as are changes to the wireless free Microsoft practice tests(http://www.examshots.com/vendor/Microsoft-1.html)

Security changes come with the addition of authentication improvements, validation and revocation checking procedural changes, and key management. A RADIUS server is required to perform authentication and can provide authorization and auditing improvements. The following sections describe these changes.
Authentication Improvements
Microsoft Internet Authentication Services (IAS) can be used as the RADIUS server. Both computer and user authentication flexibility is added by the ability to use Exten-sible Authentication Protocol (EAP) types, including the following:
? PEAP-EAP-MSCHAPv2 Protected Extensible Authentication Protocol (PEAP) EAP-MSCHAPv2 passwords are protected by Transport Layer Security (TLS). Mutual authentication is provided because the server also is authenticated by the client. The RADIUS server is used for authentication and must have a certificate, but client com?puters do not need them. Instead, the user provides a Microsoft exam(http://www.upcert.com)
user ID and password.
