The Future of Mobile Security

As the millions of laptops in use and connected to the Internet, it makes sense that IT managers are most concerned about them. However, there are more mobile phones in use than computers. Most cell phones purchased today have the ability to not only receive email and other short messages and to act as pagers, but also to browse the Web, compose emails and Instant Messages (1M) and keep track of appointments and other personal information. The use of Wi-Fi is growing rapidly, and hotspots are increasingly prevalent in high-traffic locations. The demand of mobile computing devices including laptops, personal digital assistants (PDAs), and wearable computers has created a demand for wireless personal area networks (PANs). Networks allow computers to share information and resources. Connecting computers together is no easy task. In addition, mobile devices almost always communicate via a wireless connection, a medium that is still notoriously insecure. Data security, including encryption/decryption, has not been widely implemented on most mobile devices. In short, mobile device makers have focused on utility, not security, leaving the devices vulnerable. The mobile devices in the enterprise make it imperative for IT managers to take an unmoving stance on the security of these devices. Whether sanctioned by IT or not, the diverse devices used by today's mobile work force must be made to withstand withering security requirements to protect the integrity of corporate data, and the devices that IT managers think are the most vulnerable-or the most worthy of protecting-may not be the ones most at risk. In this thesis, the mobile security issues regarding to mobile hardware and software are discussed from the future point of view; on the basis of current malicious activities mobile security threats and preventions against them are also highlightedFaculty of Technolog
