Mobile security, or mobile device security, is the protection of smartphones, tablets, and laptops from threats associated with wireless computing.[1] It has become increasingly important in mobile computing. The security of personal and business information now stored on smartphones is of particular concern.[2]
Increasingly, users and businesses use smartphones not only to communicate, but also to plan and organize their work and private life. Within companies, these technologies are causing profound changes in the organization of information systems and have therefore become the source of new risks. Indeed, smartphones collect and compile an increasing amount of sensitive information to which access must be controlled to protect the privacy of the user and the intellectual property of the company.
The majority of attacks are aimed at smartphones.[citation needed] These attacks take advantage of vulnerabilities discovered in smartphones that can result from different modes of communication, including Short Message Service (SMS, text messaging), Multimedia Messaging Service (MMS), wireless connections, Bluetooth, and GSM, the de facto international standard for mobile communications. Smartphone operating systems or browsers are another weakness. Some malware makes use of the common user's limited knowledge. Only 2.1% of users reported having first-hand contact with mobile malware, according to a 2008 McAfee study, which found that 11.6% of users had heard of someone else being harmed by the problem. Yet, it is predicted that this number will rise.[3]
Security countermeasures are being developed and applied to smartphones, from security best practices in software to the dissemination of information to end users. Countermeasures can be implemented at all levels, including operating system development, software design, and user behavior modifications.
