mobile security

Mobile security, or mobile device security, is the protection of smartphones, tablets, and laptops from threats associated with wireless computing. It has become increasingly important in mobile computing. The security of personal and business information now stored on smartphones is of particular concern.
More and more users and businesses use smartphones to communicate, but also to plan and organize both their users' 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.
All smartphones, as computers, are preferred targets of attacks. This is because these devices have family photos, pictures of pets, passwords, and more. For attackers, these items are a digital passport to access everything they would need to know about a person. This is why attacks on mobile devices are on the rise. These attacks exploit weaknesses inherent in smartphones that can come from the communication mode—like Short Message Service (SMS, aka text messaging), Multimedia Messaging Service (MMS), WiFi, Bluetooth and GSM, the de facto global standard for mobile communications. There are also exploits that target software vulnerabilities in the browser or operating system while some malicious software relies on the weak knowledge of an average user.
Security countermeasures are being developed and applied to smartphones, from security in different layers of software to the dissemination of information to end users. There are good practices to be observed at all levels, from design to use, through the development of operating systems, software layers, and downloadable apps.
