2. Best security practices for securing mobile operating systems
2.1 Different Mobile Operating systems
Based on the model details and application level features of the mobile phones the best
suited Mobile Operating Systems (OS) is considered. Among the available mobile operating
systems some of the OS are elaborated below:
iOS: Only for the Apple devices such as iphone this iOS operating system is used. Over
last few years the market share of the iOS is growing rapidly and reached up to 16% (Mutchler et
al. 2015). The iOS operating system is consists of core OS, core services and media. The service
of iOS is comprises of high level framework that are used for the graphics, videotechnologies
etc.
Android: Google and Open Handset alliance has combiningly developed the Android
operating system. The market usability implies that android is the second widely used OS that is
comprises of Linux Kernel, using C and C++ coding open source Library, application framework
(Turland et al. 2015).
Apart from iOS and Android, windows blackberry OS are used for windows phone and
blackberry mobile phones respectively (Chen et al. 2016). Security is the most important aspect
that has to be considered for any mobile device to keep their data secured from the external
attackers.
2.2 Different security practices for securing mobile operating systems
In order to secure the mobile operating system, different security practices and policies
are available in the market those are strictly needed to be adopted and maintained by the system
developers. According to Abirami and Venkataraman (2016), it has already been established

that, Smartphone requires good security software to fight against the battle of array of hacks and
flaws. Due to cybercrime rather StageFright the reputation of mobile operating systems is
getting damaged each day (Xu et al. 2017). As android phone is open sourced and in this
operating system the developers can utilize different complex C ++ programming or JAVA also
as a result the cyber criminals can easily insert the malicious codes to the application. Mainly for
the malware this is referred to as one of the massive targets. Talha, Alper and Aydin (2015),
stated that, over 96% of malware targeted android are reported in the last 2 to 3 years over 24
million of apps attack.
The Android Operating System fails to develop automatic alert for any highlighted issue.
With the technical development in the business areas the Smartphones have become widely used
tools for successful web access. As a result the users are avoiding incorporating IT to their
source of technical leadership. This is all done because Mobile phones give cutting edge
technologies (Harris and Patten 2014). The user of the mobile phones look for consumer focused
vendors who are catering to their personal requirements.
2.3 Other standards to consider
Mostly for fraudulent and unethical hackers the Smartphones are becoming the most
attractive targets because of the combination of increasing ownership of the Smartphones and
usage of different valuable data services with the devices. Regardless of the type of the
Smartphones, proper even best of the security practices are required to be adopted by the
developers (Islam 2014). Security practices are intended to assist the business for taking the
necessary phases required to use the best security practice for the users of the mobile devices.
The best levels of security practices for mobile devices are as follows:

4OPERATING SYSTEM SECURITY
Choosing Mobile devices: While question raise regarding security of Smartphones, it
can be said that, all the devices are not created considering similar types of security approaches.
Ipods are developed for the general consumers thus; it is less focused on security (Shahzad
2014). On the other hand, the blackberry operating system is much focused on its operational
security because it is mainly designed for the enterprises users like law enforcement, android and
apple Smartphones. Device access is the most important component that has to be considered.
Proper authentication should be implemented to make sure that only the authorized users are
capable to access the device and its operational applications (Roesner, Kohno and Molnar 2014).
Professional setup of the operating system is the most import thing that has to be considered to
protect the mobile device from unauthorized access.
Mobile app update: Whenever update is required the mobile devices gives notification
for the requirement (Shin et al. 2014). Whereas there are certain phones which enable the users
to set up phones in a way so that it can update the application automatically. It allows the users to
get a secured and updated mobile device.
Installation of antimalware and necessary application software: Each day new
malwares attacks are getting exploited in the android and iOS application. Like other software
the antivirus software are needed to be updated accordingly. For any employee or mobile phone
user the software update should be considered as a compulsory or mandatory one (Sajid, Abbas
and Saleem 2016). Sometimes the mobile devices are found to be connected with office data
server also. Thus, accurate software update is require keeping both the office server and mobile
data protected from the external attackers.
Communication should be encrypted: In the current technology era, wireless
communication has become the most widely used application for communication. It is found that

5OPERATING SYSTEM SECURITY
most of the times, wireless communication is intercepted that is allowing the information getting
manipulated. (Rahimi et al. 2014) Thus, it is the responsibility of the employees and users to
encrypt all possible communication.
For different brand the mobile operating system differs and the policies for the different OS are
as follows:
Policy Android 3.0 OS Windows OS IOS Blackberry OS

Security policy for Windows phone:
 Required password
 Minimum length of the password
 Allowance for simple password
 History of the password

6OPERATING SYSTEM SECURITY
For the iOS operating system the policies are as follows:
 Pass-code needed
 Allowance for simple values
 Length of the pass-code
 Length of the pass-code
 Maximum age for the pass-code
The policy for android (3.0) phone:
 Complex password is needed
 In password minimum number of letter are needed
 Minimum letters and lowercase letters
 Requirement for storage encryption
Conclusion
From the overall discussion it can be concluded that, in this current age of technology,
each of the mobile operating system supports different kinds of policies and practices
enforcement. Thus, this is the responsibility of the consumers to choose the most suitable OS that
has to be deployed. OS helps the users to run all necessary application in the mobile devices
with proper security and privacy. Any particular Mobile app can become a profitable business
only when it is an embedded operating system that is researching the EOS. Companies those are
dependent on rugged operating devices helps to run windows embedded operating system which
needs to consider their next step for supporting the business. Moreover it can be said that with
the help of mobile operating system the issues of traditional business can be eventually reduced

and minimized accordingly. In order to secure the mobile operating system certain mandatory
recommendations are needed to be followed by and the recommendations for the research are
elaborated below:
Recommendations
Credential password usage: In order to secure the mobile operating system from the
external assaults it is necessary for the users to develop credential password so that the no
unauthenticated users can access the information from the OS platform.
Cryptography support: It is necessary for the developers to incorporate proper
cryptographic support to encode confidential information. With accurate cryptography key
generation only the authenticated users will be able to decrypt the data whenever required.
However during the application of the cryptography algorithm potential function and condition
are also required to be considered.
Antivirus software: In order to avoid all unwanted file corruption and data hijack proper
antivirus is required to be applied to the mobile operating system.
