App Security Checklist
Make use of the iOS Keychain for storing sensitive user data. This system-level feature enables secure storage of values such as passwords or credit card information.2. Enforce App Transport Security
Apple has implemented App Transport Security (ATS) to prohibit unclear HTTP links. Ensure you always prefer HTTPS to keep your network communication secure and heavily minimize the risk of man-in-the-middle attacks.
3. SSL Pinning
Add SSL Pinning to ensure secure interactions between the server and the iOS app. This binds a public key to a specific user, providing extra protection from man-in-the-middle attacks.
4. Debug Code
Ensure to remove any debug code before deploying the application. Debugging processes often contain sensitive information that can make your app an easy target for hackers.
5. Check the Authenticity of Third-Party Libraries
Always verify the integrity and authenticity of any third-party libraries you use in your app. These components can lead to severe security vulnerabilities if corrupted or compromised.
6. Data Protection
Apply Data Protection measures to ensure that your app’s data remains inaccessible when the device is locked. Leverage iOS’s Data Protection API to encrypt data based on varying security levels.
7. Screen Recording and Capture
Prevent unauthorized screen recording and capturing. Implement measures to detect and block such actions to protect sensitive on-screen information during app usage.
8. Disable Auto-Correction & Enable Masking
Disable the auto-correction feature on text fields containing sensitive information to prevent unintended data leaks. Similarly, enable masking so long-term alphanumeric values (e.g., passwords, credit card numbers) are displayed as special characters while being input, helping to protect the visibility of this data.
9. Dynamic and Static Analysis
Perform both dynamic and static analysis throughout the app development lifecycle. These methodologies help detect potential security vulnerabilities in real-time and test source code respectively. Make sure to fix any uncovered risks before propagation to ensure a safe environment for the users.
