Mobile app security (iOS/Android): storage, transport, code integrity, biometrics, permissions.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

rule_id: codeguard-0-mobile-apps

## Mobile Application Security Guidelines

Essential security practices for developing secure mobile applications across iOS and Android platforms.

### Architecture and Design

Implement secure design principles from the start:
- Follow least privilege and defense in depth principles
- Use standard secure authentication protocols (OAuth2, JWT)
- Perform all authentication and authorization checks server-side
- Request only necessary permissions for app and backend services
- Establish security controls for app updates, patches, and releases
- Use only trusted and validated third-party libraries and components

### Authentication and Authorization

Never trust the client for security decisions:
- Perform authentication/authorization server-side only
- Do not store user passwords on device; use revocable access tokens
- Avoid hardcoding credentials in the mobile app
- Encrypt credentials in transmission
- Use platform-specific secure storage (iOS Keychain, Android Keystore)
- Require password complexity and avoid short PINs (4 digits)
- Implement session timeouts and remote logout functionality
- Require re-authentication for sensitive operations

How to install

The exact contents, by fingerprint
mdr add cisco-ai-defense/skill-scanner/.cursor/rules/codeguard-0-mobile-apps.mdc@sha256:06d02cabcb1bf3c9

The line at the top of this page pins the label v1.0.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
