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 amobile 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 theapplication developer end, application stores end, and operating system and mobile device manufactures end bypreventing the user from usingnon-recommended applications (which may be malicious) and consideringbiometric features for the authentication of real users in the mobile devices.
