Additional authentication requirements are necessary 220-701 when mobile devices connect to networks. The way in which they authenticate might depend on the type of connection and communication protocols used. Many devices can connect in a number of ways. For example, wired network interface cards and wireless cards can be used to connect PDAs to LANs. PDAs might have built-in wireless connectivity. Phones, Pocket PC phones, and smart phones use various traditional and modern telephony communica?tion protocols. In addition to authenticating the initial access, these protocols might also be able provide data synchronization and they might require additional authentication for connections to internal applications.
Analyze products that improve authentication to devices themselves.These products can strengthen network authentication by preventing access to the device
that uses a different authentication scheme to access the network. Some of these authentication products, if tampered with, destroy data that is resident on the mobile device. Determine what problems this might ...
... cause and whether this is an acceptable or preferred MCSE exams security solution for the organization.
Analyze intermediary needs for authentication. Intermediary needs are the requirements related to the equipment of ISPs and mobile communication carriers. The mobile device might be required to authenticate to the ISP or carrier's device, and the carrier's device might need to authenticate to computers on the organization's network. Figure 10-1 shows an example of this. In the figure, mobile devices connect to the carrier's network. A Microsoft Mobile Information Server Carrier Edition computer on the carrier's network connects to a Microsoft Mobile Informa?tion Server (MMIS) on the organization's network.

Analyze the requirements of intermediary systems. Determine how the requirements of intermediary systems will affect authentication between interme?diary systems, between devices and intermediary systems, and between intermediary systems and systems on the organizations network. Figure 10-1 shows the path between the mobile device and the points along which there might be or should be authentication.
Analyze the weaknesses inherent in permitting communications across public networks or networks not under the direct control of the organiza?tion. Determine where authentication can strengthen the security posture of these communications and mitigate the MCSE 2003 certification of potential weaknesses.
