Network Security Setup

About

The Network Security Setup skill establishes a zero-trust network architecture within the Claude Code sandbox environment to protect your development workflow. It allows you to define strict network isolation policies, ranging from complete offline modes to granular whitelisting of trusted domains like npm, GitHub, and Docker Hub. This skill is essential for enterprise security compliance, as it prevents data exfiltration via prompt injection attacks and ensures that sensitive credentials are never exposed within the sandbox configuration, keeping your internal infrastructure and secrets safe.
