Performance Analysis of Intrusion Detection Systems for Smartphone Security Enhancements

In order to protect user privacy and a smartphone from imminent security breaches, it is necessary to have an intrusion detection system (IDS). According to stock market surveys, Android is the most popular mobile operating system (OS). By 2021, smartphone traffic is expected to exceed that of personal computers. This makes the smartphone most attractive for potential attacks. The risk is due to the creation of malicious applications and gaming, the majority of which are freely available to users. The main problems with the IDS developed for Smartphone Technology are the CPU, memory, and their battery usage, because there are limited energy resources for smartphones and other mobile devices. The other problem is that most other security devices including anti-malware and antiviruses continuously need to upgrade their signatures from servers and upgrading antivirus signatures is more energy consuming. At the same time hackers use innovative types of attacks to hack smartphones while signatures for these do not exist at the server side. In this study the main focus is on the performance analysis of IDS for Smartphone communications and transactions. In addition the implication of this analysis with a view to improving existing intrusion detection systems is discussed. A detailed comparative study of existing method of intrusion detection system for smartphone security improvement and enhancement is presented to point out the pros and cons of the currently in use intrusion detection technique for smartphones.
