Comparison between android and iOS Operating System in terms of security

Abstract

This paper compares between android and iPhone Operating System (iOS) mobile operating systems (MOS) that available in the market which is more specific on the security issue. These issues are reportedly the concern of not only the mobile customers but also the software developers. In achieving security requirements, the MOS developers need to know how to achieve the criteria. The security requirements for MOS are Application Sandboxing, Memory Randomization, Encryption, Data Storage Format and Built-in Antivirus. Application sandboxing enforces permissions, privileges, directories, entitlements and kernel access for a mobile app. Memory randomization ensures that the memory regions of mobile application as well as system shared libraries are all randomized at device and application start-up. Encryption is performed on disk or filer/folder level and also at the interprocess communication level. It is difficult to speak in favor or against the android or the iOS operating system in terms of better security. The way of using the device plays a major role in determining the security level. In terms of storage, all data are stored in Data Storage Format. Data can be stored at internal storage or external storage. To protect the MOS from virus attacks, antivirus need to be installed for increasing security areas.
