As the number of smartphone and tablet devices increases, so does the risk that hackers and computer criminals will target these devices. Since they were first introduced, certain mobile devices have been vulnerable to eavesdropping and fraudulent charges. In addition, many of them automatically track a user's location.

The major security risks associated with mobile devices include:28 Malware-Android apps, in particular, are vulnerable to malware because of the platform's openness. To guard against malware threats, users have to upload the most recent versions of the operating system and use mobile security tools.

Premium SMS billing-With their devices' vulnerability to malware, smartphone users face an added risk of subscribing to premium text-messaging services that charge every time users interact with them. Most cell phone carriers allow subscribers to block premium SMS messaging, however.

E-mail and SMS phishing-Because it is more difficult to establish a link's legitimacy on a mobile device, mobile users are more likely to click on them, which is a phisher's dream come true.

Mobile users should therefore use a lot of caution when using e-mail on these devices. Spyware-Commercially available software can be used by intruders to track and control the user's mobile activities. Malicious Web sites- These could pose a threat in the future, given that many smartphone browsers are based on a browser engine with vulnerabilities. Many of the recommendations discussed in Chapters 4 and 5 apply here.

Never leave your mobile device unlocked. Never leave it unattended. Always protect it with a password.
