Mobile App Security.

The practice of designing, building, and testing iOS and Android applications to protect user data, prevent reverse engineering, and resist runtime tampering. It belongs to the Mobile Security category of cybersecurity.

The practice of designing, building, and testing iOS and Android applications to protect user data, prevent reverse engineering, and resist runtime tampering.

Mobile app security covers the controls that protect a mobile application across its life cycle: secure coding, secure storage (Keychain, Android Keystore), certificate pinning, code obfuscation, anti-tamper checks, and proper use of platform sandboxing and permissions. It also includes server-side hardening of the APIs the app consumes. Threats include reverse engineering of the binary, runtime hooking with Frida or Objection, SSL stripping on hostile networks, and abuse of weak deep links or exported components. Industry references such as the OWASP MASVS and MASTG define a verifiable baseline, and Apple App Store and Google Play policies impose additional review gates.

Defences for Mobile App Security typically combine technical controls and operational practices, as detailed in the full definition above.

Common alternative names include: App security, Mobile application security.
