3G Safeguards: Incomplete, Getting Better

摘要

With more organizations using mobile broadband networks, IT managers should be very concerned about security. Safeguarding data as it travels the airwaves may be only part of a mobile security policy-enterprises must secure their devices and the data they store-but the airwaves are a good place to start.rnThe good news about wireless security is that today's mobile broadband networks have some enhanced security functions built in. The latest 3G tech-rnnologies, including WiMax, have robust encryption options. AT&T and T-Mo-bile provide High Speed Packet Access with a 128-bit Kasumi encryption algorithm. CDMA2000, offered by Sprint and Verizon Wireless, sports 128-bit Advanced Encryption Standard encryption. WiMax also uses AES.
