way to address this shortcoming is through enhanced user authentication
and location profiling which is a byproduct of real-time call rating.
Still another set of latency issues arise in the transcoding (i.e.,
presentation and adaptation) of Internet data for display and processing
on wireless devices. Websites combine presentation and content data
using HTML, which must be transcoded for wireless device use. Use of
XML gets around that problem. Widespread adoption of the WAP with
its XML-compliant WML has provided an interim solution. However,
conversion of WAP at a carrier's gateway poses a security risk for the
enterprise. While 3G wireless and wired broadband networks will
ultimately use end-to-end IP (Internet Protocol), enterprise solutions in
the near term are likely to require middleware to ensure security and
high throughput for transactions. Figure 12.7 outlines the migration to
3G networks.
As wireless devices become smarter, faster and more powerful, they
will undoubtedly pose a new enterprise security risk. It is anticipated
that these devices will exchange not only voice and data, but also
executable code. Distributed object frameworks support remote invocation
of code. As mobile IP, distributed object frameworks and mobile code
technologies, such as Java and Jini, merge in the future, it is safe to
assume that we will have new security and privacy risks.
If a company is looking to deploy some kind of wireless business-tobusiness
solution, there are three basic, but very important things one
can do to protect one's data now and limit the impact of IP theft:
1. The more network-centric solutions designed a priori, with the least
amount of sensitive data residing in the handheld, the better off one
