Protection Software for Mobile Operating Systems

Threat of software viruses aimed at mobile operating systems' segment is growing. This is confirmed by statistic numbers on malware installations. A comparative analysis of mobile operating system is performed. Model of attacking actions detection is suggested. Specific variant of attacking action called Cloak & Dagger is described in details. Algorithm for detecting malicious software packages that perform Cloak & Dagger attack is proposed. Software that implements the algorithm is developed. Therefore experimental studies on a variety of mobile applications are carried out. The results of experimental studies show that taking into account the presence of multiple permissions in the application does not allow to identify all potentially dangerous applications in mobile operating system.
