Wireless devices, like all technologies that provide external access to corporate networks, present security challenges. With wireless standards and practices still rapidly evolving, it is important to understand the strengths and limitations of available technologies in order to implement a secure solution. Extending current security policies to encompass wireless devices requires an understanding of the security features of both wireless devices and wireless networks.
Purpose of the Study
The purpose of the study was to assist in the decision whether Lotus Development should extend current security policies to encompass wireless devices. The following are critical security questions:
• What challenges are faced with wireless security?
• How can you verify that the device being used is actually in the hands of an authorized user? How can you enhance the security of the device?
• How secure is the over-the-air network between the organization and the wireless device?
• How can you secure the wireless session?
• Should Lotus development include wireless devices in their security policies?

Research Methods and Procedures
Through traditional and electronic research of books, periodicals, and business journals, secondary research was conducted. Figures were constructed through extensive research and study of interactions of networks.
Wireless Security Challenges
Mobile devices and wireless networks rely on a broad spectrum of technology, much of it cutting-edge. In comparison to PCs, each class of mobile device currently represents a unique hardware and software platform. Mobile phones, for example, have varying capabilities and limitations both as computing devices and as client devices accessing corporate networks. The wireless networks that support mobile devices are similarly diverse.
By relying on industry standard protocols like TCP/IP, HTTP, SMTP and TAP, Mobile Services supports many of the major wireless networks currently in operation. This standards-based approach also provides MSD with a common security model that can operate across wireless networks, while at the same time taking some of the complexity out of doing business with different wireless network providers (Braden 1997).
However, it is important to understand that there is currently no industry-wide security standard that will work on every mobile device and on every wireless network, in the way that X.509 and SSL span the PC universe. MSD bridges this gap wherever possible by adding its own security features (Freeburg 1991).
Mobile Device Security
Most mobile devices currently provide only a simple username/password combination to block use of the device (a few also offer local data encryption). And since most users do not employ even this rudimentary level of security, mobile devices like pagers, mobile phones and PDAs are essentially unsecured (Aziz 1993).
