The application uses Tauri 2.x's enhanced permission system for secure access control:

1. Core Permissions

   • Explicitly defined permissions for each capability
   • Granular control over API access
   • Window-specific permission sets

2. File System Security

   • Path traversal protection
   • Secure file operations
   • Directory scoping
   • Permission guards on file operations

3. IPC Security

   • Command permission validation
   • Message integrity checks
   • Scoped API access

1. Permission Guards

fn attachment_guard<R: Runtime>(
    app: &AppHandle<R>,
    cmd: &tauri::command::CommandItem,
) -> Result<(), tauri::Error> {
    if cmd.message.permissions().contains(&"fs:default".parse().unwrap()) {
        Ok(())
    } else {
        Err(tauri::Error::PermissionDenied)
    }
}

2. Secure Path Handling

let app_dir = app.path().app_data_dir()
    .ok_or("Could not resolve app data directory")?;
let attachments_dir = app_dir.join("attachments").clean();
let file_path = attachments_dir.join(&file_id).clean();
if !file_path.starts_with(&attachments_dir) {
    return Err("Invalid file path".to_string());
}

3. Permission Configuration

{
  "security": {
    "capabilities": {
      "default-window-capabilities": {
        "permissions": [
          "core:default",
          "fs:default",
          "window:default"
        ]
      }
    }
  }
}

1. Always use path validation
2. Implement proper error handling
3. Use permission guards
4. Validate file types
5. Check file sizes
6. Use proper scoping

1. Validate all inputs
2. Use proper error handling
3. Implement rate limiting
4. Use secure defaults
5. Follow least privilege principle

1. Proper CSP configuration
2. Limited domain access
3. Secure IPC communication
4. Permission-based API access
