Android Security Hardening 🛡️🔐

Professional security practices for protecting sensitive user data, identity, and application integrity on Android devices.

⚡ When to Use

• Biometric Authentication: Fingerprint/Face ID for app lock.
• Local Encryption: Securing login tokens or user profiles.
• Keystore Management: Safe storage of cryptographic keys.
• Root/Emulator Detection: Verifying device integrity for high-risk apps.
• Certificate Pinning: Hardening HTTPS via network security config.

🏗️ The 5 Pillars of Security

1. Identity: Strong authentication (OIDC, Biometrics).
2. Confidentiality: Encrypting data at rest and in transit.
3. Integrity: Preventing tampering (App signing, Root check).
4. Available: Ensuring resilience (DDoS protection, Offline access control).
5. Audit: Logging security-relevant events safely.
