Smartphone usage has increased exponentially in the recent years. Android and iOS are the most popular smartphone platforms, while the ease of use along with the computational power to handle a wide array of applications attracts millions of users worldwide, also raises the security concerns on these platforms. This paper presents a comparative analysis between Android and iOS on a wide range of security aspects. It analyzes data for the period 2015-2019 and gives a detailed snapshot of not only the quantum of vulnerabilities, but also their impact. In addition, the paper leverages the well-established security triad i.e. CIA (Confidentiality, Integrity, Availability) to compare both the operating systems. The comprehensive and pragmatic approach taken in the paper makes it easier to infer that Android is more susceptible to security breaches and malware attacks as compared to iOS. Hence, researchers should divert their efforts and focus on finding solutions to problems pertaining to Android. The paper concludes by laying down future research directions and scope of work, which can be leveraged not only by application developers, but also by researchers. This will help make Android safer for users and will further increase its demand as a mobile operating system.

近年来，智能手机的使用呈指数增长。Android和iOS是最受欢迎的智能手机平台，其易用性以及处理各种应用程序的计算能力吸引了全球数百万用户，这也引发了这些平台的安全性问题。本文对Android和iOS之间的广泛安全性方面进行了比较分析。它分析了2015-2019年期间的数据，不仅提供了漏洞数量的详细快照，还提供了漏洞的影响。此外，本文还利用了完善的安全三合会，即CIA（机密性，完整性，可用性）来比较两个操作系统。本文采用的全面而务实的方法使我们更容易推断出，与iOS相比，Android更容易受到安全漏洞和恶意软件攻击。因此，研究人员应转移精力，专注于寻找与Android有关的问题的解决方案。本文通过确定未来的研究方向和工作范围进行总结，这不仅可以由应用程序开发人员利用，而且可以由研究人员利用。这将有助于使Android对用户更安全，并将进一步增加其作为移动操作系统的需求。但也有研究人员 这将有助于使Android对用户更安全，并将进一步增加其作为移动操作系统的需求。但也有研究人员 这将有助于使Android对用户更安全，并将进一步增加其作为移动操作系统的需求。
