Wireless networking offers a degree of freedom freedom for users of portable and handheld computers to roam where they will and freedom for companies to place computers in new locations without having to run network cabling. With that freedom, however, comes increased vulnerability. Because wireless networking does not share the same physical security of a wired network, understanding the security options for a wireless network is of paramount importance. This lesson introduces you to the standards, implementations, and security options for wireless networks. This lesson also shows you how to configure a computer running Windows XP Professional to participate as a client in a wireless network.

In some scenarios, a multiple-domain forest is required. The important point to remember is that you should never create a multiple-domain forest simply to reflect the organizational structure of your business. That structure the business units, divisions, departments, and offices will change over time. The logical structure of your directory service should not be dependent solely on organizational characteristics. Instead, your domain model should be derived from the characteristics of domains themselves. Certain properties of a domain affect all objects within the domain, and if that consistent effect is not appropriate for your business requirements, you must create additional domains. A domain is characterized by the following:

When the security mode is set to Message or TransportWithMessageCredentials, the AsymmetricSecurityBindingElement and TransportSecurityBindingElement classes are added (respectively) to the stack. 8 discusses the properties associated with these elements. The last change you can make to basicHttpBinding is to set MessageEncoding to Message Transmission Optimization Mechanism (MTOM ). This causes TextMessageEncodingBindingElement to be replaced with MtomMessageEncodingBindingElement. This class doesn t have any additional properties beyond the standard TransportBindingElement class.

Each of these validators includes both a client-side and server-side component. The client-side component runs on the user s browser in the form of a JavaScript. Using the client-side script does not improve the security of your application. Client-side valida tion gives immediate feedback to legitimate users who accidentally enter invalid input into a box. However, malicious attackers will simply bypass the client-side scripts.
