tauri-lifecycle-security_skill

Overview

This skill helps developers identify and mitigate security threats across the full Tauri v2 application lifecycle: development, build, distribution, and runtime. It distills practical controls, configurations, and verification steps so teams can reduce attack surface and enforce least privilege. The guidance is actionable and focused on real-world tradeoffs for desktop applications that combine a Rust backend and a WebView frontend.

How this skill works

The skill inspects each lifecycle stage and maps common threat vectors to specific mitigations: dependency scanning, development server hygiene, build system hardening, signing and key protection, secure distribution, and runtime policy configuration. It recommends concrete commands, configuration snippets, and operational practices (e.g., CSP, capabilities, scopes, prototype freezing) that you can apply directly to Tauri projects. It also explains why each control matters and where residual risk remains so teams can prioritize controls.

When to use it

• When starting a new Tauri project and defining security requirements
• Before integrating third-party dependencies or updating core runtime components
• When configuring CI/CD, signing keys, or release pipelines
• When enabling app updates or hosting binaries/manifest servers
• When designing runtime policies for WebView, capabilities, and file access

Best practices

• Adopt defense-in-depth: combine CSP, capabilities, permissions, and scopes
• Treat frontend code as untrusted; validate and authorize in the Rust backend
• Pin critical dependencies and run supply-chain scans (cargo audit, npm audit, cargo vet)
• Protect signing keys with hardware tokens and restrict their use in CI
• Harden developer machines, require commit signing, and restrict dev server exposure to trusted networks

Example use cases

• Hardening a desktop app before public release: add CSP, freezePrototype, and capability files
• Designing CI/CD for sensitive apps: use self-hosted runners or restrict third‑party access, require artifact signing
• Mitigating update tampering: publish signed manifests, checksums, and enable certificate pinning
• Creating least-privilege file access: define permission scopes that allow home access but deny .ssh and .gnupg paths
