Examples Mobile App
Mobile App Security
iOS/Android application with backend API. The device is untrusted territory - assume the attacker has full control of the client.
Mobile Architecture
End-to-end mobile application security from device to backend data stores.
The Device is Enemy Territory
Never trust the mobile client. Attackers can jailbreak/root devices, hook functions with Frida, bypass SSL pinning, decompile the app, and modify requests. All validation must happen server-side. The client is only for UX - never for security.
Mobile Device
Untrusted client with local storage and biometrics.
Network Layer
TLS with certificate pinning. Assume network is hostile.
API Gateway
Rate limiting, authentication, and WAF protection.
Backend Services
API server, auth service, and push notifications.
Data Layer
Database and file storage. Most trusted zone.
