Fine-grained security features and state of the art security is provided by Virus Guard, the Android operating system security system. Android basically refers to an operating system on a mobile platform, based loosely on the Linux kernel. The Android operating system involves native program or source code writing in the Java programming language, which also includes middleware and even a number of key applications. The unique feature of Android phones is that they are controlled by Java language libraries that have been developed by Google. Android phones have become extremely popular worldwide. The security system of Android is the best security system there is.
Devices such as the Blackberry and iPhone were comprehensively studied to develop the security system of the Android, which is far superior to any security system existing at present. Virus Guard is the security system of the Android operating system. It enables the user to scan for and identify malicious software and malicious programs like Viruses, Spyware, Malware, Trojans and Worms. A new security system is also being developed which is going to better the Virus Guard that is already in use. The new security system will feature a Firewall, Mail Scanner, Spam Guards, and Backup features. Security is of the utmost importance for the smartest operating system in the market.
The security system of the Android has been developed in a multi layered hierarchy. A number of processes or applications are designed to run on the Android OS at the same time. Security for these applications and between the application and the system are provided at the process level of the particular applications, based on the Linux kernel. User name and User IDs are required for running all applications, so that no malicious programs can run any application on its own, without the knowledge of the user. Finer security is provided using a mechanism based on “permissions”, which decides on the particular tasks that a particular application or process is authorized to perform. It makes sure that a particular application or process does not overstep its authority. Permission is also required for a process to gain information about some specific data.
The overall design of the Android security system is quite unique. It has been designed in a way that no application or process, acting on its own, can adversely or negatively impact the running of another process, application, the OS, or even the user. This is inclusive of gaining information about some particular data of the user, some network tasks, and a number of other tasks. An application or process has an isolated existence. It can, in no way disrupt the functioning of another application or process simply because it doesn’t have “permission”. Only in extremely rare cases is a process allowed “permission” to access data from other applications, and this is done by extending the permission, by the means of user generated commands.All these features make the security system of the Android the best there is. No other mobile operating system is as well equipped in terms of security features as the Android OS.
