Application in the smartphones have become in the recent years. Smartphone have provided many services like mobile payment system, application market(i.e playstore). Also the no of vulnerabilities of application is also increasing. so in this research i had tried to cover the Vulnerabilities & solutio for smartphone security.
Smartphone provide many feature as a result they have become perfect target for different virues & Vulnerabilities. According to a research study 80-90% android mobiles in market are more vulnerable to security issues than IOS in Iphone.
Smartphone OS : is a system software that run on smartphone & allows them to execute the applications.
Smartphone OS Feature : Since every OS provides different features they can provide camera, fingerprint, sensor support as well as works with hardware features also.
Types of OS : Android & IOS
These 2 OS are majorly used OS.Both the OS have 4 layers.
Android
Linux Kernel -In charge for power management, Virtual memory & network
Libraries - different libraries have differnt function in Andriod mostly libraries are java based.
Java API framework - used for creating Androi Application
System Apps - since it supports 3rd party application also there are different layers in android security like
security at OS level, Mandatory application sandbox, secure inter process, Application signing, Application-defined & user-granted.
IOS
Core OS - low level feature like bluetooth framework.
Core Service-high level feature like cloud kit framework
Media Layer -includes game kit helps in using music,animation, videos etc.
Cocoa Touch - framework used for creating IOS application
MALICIOUS ATTACKS - below are few malicious attacks
Malicious Applications - Malware,Virus,Spyware,Trojan
Software Vulnerabilities - Adware apps, Fake apps, Backdoor
Threats or Attacks - Social Engineering, Phishing app, Man-In-The-Middle (MITM), Mobile botnet
MOST WANTED MOBILE MALWARE FAMILIES
Triada is one of the most wanted malware which was supported on Android OS.This malware uses a backdoor to infect OS processes and provides a remote access for stealing money from users.
SECURITY SOLUTIONS FOR SMARTPHONES
Malware Detection Techniques -Signature based techniques, Machine learning based techniques
Countermeasures against Malware -The users’ knowledge about Smartphones malicious risks, Install apps from trusted sources, The security of wireless networks, Prevent Root (Android) and Jailbreaking (iOS), Keep smartphone OS up to date, Encrypt Smartphone, Encourage Smartphone Users to Install Mobile Security Software
CONCLUSION -we examined current viable solutions for smartphone users by concentrating on existing mechanisms, and we proposed some future paths for cyber security experts to enhance this study field.
