- Platform-Specific Vulnerabilities: Mobile apps operate within a different ecosystem compared to web applications. They utilize different programming languages, frameworks, and libraries. As a result, vulnerabilities specific to mobile platforms may not be adequately addressed during web security testing.
- Client-Side vs. Server-Side Focus: Web security testing often emphasizes server-side vulnerabilities, such as SQL injection or cross-site scripting (XSS). Mobile apps, however, are more susceptible to client-side issues like insecure data storage, improper authentication handling, and local storage vulnerabilities.
- Device and OS Diversity: Unlike web applications, mobile apps run on various devices with different operating systems and versions. This fragmentation makes it challenging to cover all possible device-specific security issues during web-focused testing.
- Lack of Web Components: Some mobile apps do not use web views or browser-based components, reducing the relevance of web security testing methods.
- Data Exposure through APIs: Mobile apps frequently rely on APIs to interact with backend services. While web security tests might address API security, they might not consider mobile-specific issues like hardcoded API keys or insufficient data encryption on mobile devices.
- Offline Security Concerns: Mobile apps often store data locally, allowing them to work offline. This introduces additional security considerations not present in web applications, such as encryption, data synchronization, and secure storage of sensitive information.
- Permission Handling: Mobile apps frequently request various permissions to access device features. Web security testing might not account for improper or excessive permission handling by mobile apps.
- Jailbroken/Rooted Devices: Mobile apps installed on jailbroken or rooted devices may be susceptible to additional security risks that traditional web security tests might not account for.
