How does this skill prevent data exfiltration?

It implements strict network isolation and domain whitelisting, ensuring Claude can only communicate with approved, safe domains and blocking attempts to send data to unknown external servers.

Is there a mode for completely offline development?

Yes, the 'No Network Access' mode provides complete isolation for maximum security, disabling all external connectivity for highly sensitive projects.

Does this skill handle secret management?

It provides best practices for environment variables, specifically identifying which variables are safe to include in the sandbox and which must stay in local .env files to prevent credential leaks.

Can I use this with internal company registries?

Yes, the skill includes 'Custom Access' and 'Enterprise Configuration' modes specifically designed for internal npm, Docker, or other private corporate registries and proxies.

What happens if I try to access a domain not on the whitelist?

The network policy will block the connection attempt, protecting your environment from unauthorized external calls while providing feedback to help you adjust your whitelist if necessary.

Seguridad y Pruebas

Configures secure sandbox network isolation through domain whitelisting, custom access policies, and protected environment variable management.

Acerca de

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.
