Nowadays, the usage of smartphones and their applications have become rapidly popular in people's daily life. Over the last decade, availability of mobile money services such as mobile-payment systems and app markets have significantly increased due to the different forms of apps and connectivity provided by mobile devices, such as 3G, 4G, GPRS, and Wi-Fi, etc. In the same trend, the number of vulnerabilities targeting these services and communication networks has raised as well. Therefore, smartphones have become ideal target devices for malicious programmers. With increasing the number of vulnerabilities and attacks, there has been a corresponding ascent of the security countermeasures presented by the researchers. Due to these reasons, security of the payment systems is one of the most important issues in mobile payment systems. In this survey, we aim to provide a comprehensive and structured overview of the research on security solutions for smartphone devices. This survey reviews the state of the art on security solutions, threats, and vulnerabilities during the period of 2011-2017, by focusing on software attacks, such those to smartphone applications. We outline some countermeasures aimed at protecting smartphones against these groups of attacks, based on the detection rules, data collections and operating systems, especially focusing on open source applications. With this categorization, we want to provide an easy understanding for users and researchers to improve their knowledge about the security and privacy of smartphones.

This work investigates issues and challenges of cyber security, specifically malware targeting mobile devices. Recent advances in technology have provided high CPU power, large storage, broad bandwidth and integrated peripheral devices such as Bluetooth, Wi-Fi, 3G/4G to mobile devices, making them popular computing and communication devices. Mobile malware has been targeting mobile devices more than ever and seems to be shifted from their traditional host, the personal computers, to more vulnerable victims. In this study, we mainly focus on malware for Android-based mobile devices. We analyze and discuss related malware and recognize its trends and challenges. We also present a comprehensive security solution that addresses the security from malware threats.

Mobile security or mobile phone security has become increasingly important in mobile computing. It is of particular concern as it relates to the security of personal information now stored on smart phones. More and more users and businesses use smart phones as communication tools but also as a means of planning and organizing their work and private life. Within companies, these technologies are causing profound changes in the organization of information systems and therefore they have become the source of new risks. Indeed, smart phones 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 smart phones, as computers, are preferred targets of attacks. These attacks exploit weaknesses related to smart phones that can come from means of communication like SMS, MMS, wifi networks, and GSM. There are also attacks that exploit software vulnerabilities from both the web browser and operating system. Finally, there are forms of malicious software that rely on the weak knowledge of average users. Different security counter-measures are being developed and applied to smart phones, 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.

The Smartphone has pervaded into all aspects of our life. It is ubiquitous owing to the availability of an array of Smartphone Applications. Nevertheless along with the large set of useful features these applications offer, there is the problem of security and privacy. These call logs, contact lists, browsing history and so on. Such data can be exposed to unethical use without the awareness of the user, which creates a great threat to the attempts to address the various data privacy issues with respect to Smartphone applications. It also explores the various defence mechanisms to address the security issues and the with useful proposals for future work.

Smartphones has emerged as most popular gadget nowadays. Smartphones provide most of functionalities of personal computers and also has developing features and applications based on internet, due to which smartphones becomes more vulnerable to security threats such as virus, worm, Trojans etc. Smartphones are constrained by storage, battery, processing so it is difficult to implement high security services on the smartphone itself. Another new technology gaining attraction today is cloud computing providing better resource utilization and improved scalability. This paper proposes a review on examining different existing architectures providing security for Smartphones

Nowadays Smart phones and other mobile devices have become incredibly important in every aspect of our life. Because they have practically offered same capabilities as desktop workstations as well as come to be powerful in terms of CPU (Central processing Unit), Storage and installing numerous applications. So, security aspect of those devices should be taken into account seriously since phone users access wide range of none secure wireless networks and download applications on free sources which may contain harmful viruses and/or malwares. The best way of securing mobile devices is to enforce good security policy through operating systems. This paper will walk around main necessary principles of security in mobile operating systems. Then will compare those principles for four main mobile operating systems such as Android from Google, BlackBerry from research motion, Windows mobile phone from Microsoft and iOS from Apple. Finally, this paper will provide some potential steps to achieve proper mobile security.

Nowadays, mobile devices have become an integral part of our daily life. These have proven to be an advantageous scientific invention that fills personal and business needs in a very efficient manner. In this era, the availability of mobile services has significantly increased because of the rich variety of mobile devices and essential applications provided by mobile device manufacturers. At the same time, numerous mobile security issues and data privacy threats are challenging both manufacturers and users. Therefore, mobile devices are an ideal target for various security issues and data privacy threats in a mobile ecosystem. In this paper, we provide a brief survey of the security challenges, threats, and vulnerabilities of a mobile ecosystem. Furthermore, we discussed some key points required to ensure mobile security and defend against data privacy threats. The emphasis of the discussion is, strong protection and the restriction of malicious activity at the application developer end, application stores end, and operating system and mobile device manufactures end by preventing the user from using non-recommended applications (which may be malicious) and considering biometric features for the authentication of real users in the mobile devices. Also briefly discussing the defense mechanisms that are considered to be a relatively better approach for securing personal and business related data or information in the mobile devices.
