Mobile application security differs from web application security in several key aspects. Mobile apps often operate in a more distributed environment, facing threats such as device theft and malware. They require specific protections against vulnerabilities related to mobile platforms (like Android and iOS), including secure storage of sensitive data and proper communication protocols. Additionally, user authentication methods, like biometric login, are more prevalent in mobile apps. Mobile applications generally have limited processing power, making lightweight security features crucial. Overall, both mobile and web applications necessitate tailored security strategies to address their unique risks and environments.
