Mobile apps handle sensitive user data — from personal information to financial credentials. A single security breach can destroy user trust and result in regulatory fines. Here are the essential security practices.
OWASP Mobile Top 10
- Insecure Data Storage: Never store sensitive data in SharedPreferences or UserDefaults without encryption.
- Insufficient Transport Security: Enforce TLS 1.3 and implement certificate pinning.
- Insecure Authentication: Use biometric auth + secure token storage (Keychain/Keystore).
- Code Tampering: Implement root/jailbreak detection and code obfuscation.
