Abstract
The objectives of this book are to investigate methods for improving the security of mobile devices operating systems through a critical review of scientific publications related to vulnerabilities in mobile device operating systems, to analyze publicly available vulnerability databases and their systems to assess the severity of damage that can be caused by malware designed for mobile devices running the Android or iOS operating system, to detect security weaknesses in web browsers for mobile devices, and to identify vulnerabilities in mobile device operating systems.

The methods used to achieve this objective are: comparative analysis, scoring method and generalization. Based on the results of the application of the comparative analysis, it is determined which of the national databases have better capabilities to filter the data and obtain adequate results when searching for vulnerabilities for mobile devices.
