Issues and Challenges in Mobile Security

Wireless networking technology is quickly changing the way networked computers communicate. The convenience offered by the ability to connect to networks using mobile computing devices has also introduced many security issues that do not exist in the wired world. Ubiquitous use of mobile phones has caused an emergence of applications targeted to mobile platforms. Since mobile devices become the major mobile platforms for users to transfer and exchange diverse mobile data over the wireless networks or wireless internet, mobile security for mobile accesses becomes very important and critical to assure secured mobile transactions, mobile data integrity and confidentiality. Mobile security also is critical to protect mobile users and mobile-based application systems from unauthorized accesses and diverse attacks. As an emerging technology, this paper discusses the security concepts, issues, and challenges in mobile accesses, summarizes and analyzes the state-of-the-art of security technologies for mobile accesses. Moreover, the paper discusses and compares the existing mobile security solutions and technologies.
