Does this skill store my API keys or secrets?

No, the skill follows a security-first policy that explicitly avoids storing secrets in configuration files, recommending the use of local .env files and environment variable references instead.

How does this skill prevent data exfiltration?

It restricts Claude's sandbox access to only whitelisted, trusted domains, automatically blocking unauthorized attempts to send sensitive data to external or malicious servers.

Can I completely disable network access for Claude?

Yes, the skill includes a specific 'No Network Access' mode designed for maximum security when working on highly sensitive or offline projects.

Can I use this with internal company registries?

Yes, the Custom Access mode allows you to whitelist internal domains such as private NPM or Docker registries and provides detailed configurations for corporate proxies.

安全与测试

Configures robust network isolation and trusted domain policies for secure Claude Code sandbox environments.

关于

The Network Security Setup skill provides a comprehensive framework for securing the Claude Code execution environment by implementing zero-trust network architectures. It enables developers to define trusted domain whitelists for package registries and APIs, configure corporate proxies, and manage environment variables safely to prevent data exfiltration and prompt injection attacks. Whether working on sensitive enterprise codebases or open-source projects, this skill ensures that Claude's network access is strictly controlled and verified, maintaining high security standards without compromising development velocity.
