Abstract

Smartphones are becoming a vehicle to provide an efficient and convenient way to access, find, and share information; however, the availability of this information has caused an increase in cyber attacks. Currently, cyber threats range from Trojans and viruses to botnets and toolkits. Presently, 96% of smartphones do not have preinstalled security software. This lack in security is an opportunity for malicious cyber attackers to hack into the various devices that are popular (i.e., Android, iPhone, and Blackberry). Traditional security software found in personal computers (PCs), such as firewalls, antivirus, and encryption, is not currently available in smartphones. Moreover, smartphones are even more vulnerable than PCs because more people are using smartphones to do personal tasks. Nowadays, smartphone users can email, use social networking applications (Facebook and Twitter), buy and download various applications, and shop. Furthermore, users can now conduct monetary transactions, such as buying goods, redeeming coupons and tickets, banking, and processing point-of-sale payments.
