Tauri Content Security Policy (CSP) Configuration

This skill covers Content Security Policy configuration for Tauri v2 desktop applications.

Why CSP Matters in Tauri

CSP is a security mechanism that mitigates common web vulnerabilities in Tauri applications:

1. XSS Prevention: Restricts which scripts can execute, blocking injected malicious code
2. Resource Control: Limits where the WebView can load assets from (scripts, styles, images, fonts)
3. Trust Boundaries: Strengthens the isolation between frontend WebView and backend Rust code
4. Attack Surface Reduction: Prevents unauthorized network connections and resource loading

Tauri operates on a trust boundary model where frontend code has limited access to system resources through a well-defined IPC layer. CSP adds an additional layer of protection within the frontend trust zone.

How Tauri Implements CSP

Tauri uses a two-part protection strategy:
