GSM and GPRS Security Analog cellular phones and networks were designed with minimal security which soon turned out to be insufficient. The GSM system provides solutions to a few important aspects of security: subscriber authentication, subscriber identity confidentiality and confidentiality of voice and data over the radio path. This paper gives an overview of the security features provided in a GSM PLMN and GPRS network. Also the SIM module, which plays an important role in GSM security, is discussed.

Goodbye WEP, Hello WPA It's no secret to most of us that wireless networks are insecure. Crackers and other snoops can easily pilfer unprotected networks, and even more alarming is their ability to tear through security methods considered relatively unbreakable just a few years ago. But a recently released security protocol seeks to erase past security flaws and shore up wireless networks of all sizes.
WPA (Wi-Fi Protected Access) addresses the immediate need for increased wireless security using technology significantly more advanced than its predecessors. Because it's part of a larger future project, WPA isn't necessarily a long-term security solution, but its impressive slate of lockdown features makes it the current wireless security champ. Let's examine the technology behind WPA and what it can do to secure your
wireless network.

The Evolution of Mobile PositioningThe intent of this article is not to scare wireless carriers or end-users, or place undue burden on the many LBS application developers and service providers. Quite the contrary, the purpose of this article is to alert the ecosystem to an issue that will most likely be critical to the long-term success of the entire LBS value chain for commercial LBS applications.
Wireless carriers should continue to deploy pre-standard solutions, work with wireless device providers to roll out standards-based clients, and work with LBS application providers to deploy well-chosen services. However, wireless carriers should limit their deployments to strategic partners while working with industry leading service bureaus and (Managed Communications Service) providers, the most likely entities to provide the MPM and mobile positioning management functions on an ASP basis on behalf of the carriers and the LBS application providers.
