"Embedded Java Security" is a specialized book that addresses the security aspects of Embedded Java. It highlights the challenges and threats that arise from the use of Java in mobile devices. The book provides a comprehensive analysis of the security model of Embedded Java compared to the Java 2 Standard Edition and examines how limited resources impact security. The authors present the main components of the Embedded Java platform and conduct an evaluation of the security features based on the MEHARI method for risk analysis and the Common Criteria method for security assessment. This evaluation is crucial for identifying areas that require security enhancement. The book is aimed at both researchers and practitioners, offering an in-depth understanding of the challenges in Embedded Java security and the security of mobile devices.
