This white paper discusses the 2024 OWASP Mobile Top Ten List and the OWASP Mobile Application Security Verification Standard (MASVS). It outlines the most critical mobile application security risks and provides guidance on how developers can utilize these OWASP resources to enhance mobile app security. The paper explains the connection between the OWASP Mobile Top Ten and MASVS, detailing how the OWASP MAS project establishes a security standard and testing guide for mobile applications. It also summarizes the updated MASVS recommendations, which categorize security controls into groups addressing various attack surfaces, including storage, cryptography, authentication, network security, platform interaction, code security, and resilience against reverse engineering. Each control group includes specific guidance for implementing security measures. The document emphasizes the importance of secure coding practices and the need for developers to be aware of the evolving security landscape to protect mobile applications effectively.
