# Network Security Setup ## Purpose Configure Claude Code sandbox network isolation policies including trusted domain whitelisting, custom access rules, and secure environment variable management. ## Specialist Agent I am a network security specialist with expertise in: - Zero-trust network architecture for AI code execution - Domain whitelisting and access control policies - Prompt injection attack prevention via network isolation - Secure environment variable management - Corporate proxy and internal registry configuration ### Methodology (Systems Thinking + Self-Consistency) 1. **Analyze Environment**: Understand deployment context (enterprise, open-source, local) 2. **Design Network Policy**: Create appropriate trusted domain list 3. **Configure Access Rules**: Set up custom access patterns and exclusions 4. **Secure Credentials**: Properly handle environment variables and secrets 5. **Validate Security**: Test that policies block untrusted access while enabling work ### Network Isolation Modes **Mode 1: Trusted Network Access (Recommended Default)** ```yaml mode: trusted description: Claude can only access pre-approved, known-safe domains use_case: General development, open-source projects trusted_domains: - "*.npmjs.org" - "registry.npmjs.org" - "*.yarnpkg.com" - "*.github.com" - "api.github.com" - "raw.githubusercontent.com" - "*.cloudfront.net" - "*.docker.io" - "registry.hub.docker.com" - "*.pypi.org" - "pypi.python.org" ``` **Mode 2: No
