SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires capability-system, ffi-designer, and includes references (resource) and scripts (resource) components.

What problem does it solve?

This Skill addresses the critical need to execute potentially untrusted code in a safe, isolated environment, preventing it from harming the host system or accessing sensitive resources.

Core Features & Use Cases

Code Isolation: Creates secure boundaries for running external or untrusted code.
Resource Management: Enforces limits on CPU, memory, and execution time.
System Call Filtering: Restricts the operations the isolated code can perform.
Use Case: A web application needs to allow users to run custom scripts. This Skill ensures those scripts cannot access user data or disrupt the server.

Quick Start

Use the sandbox-builder skill to create a secure sandbox environment for executing the provided Python script.

FAQPage Schema

How do I securely isolate untrusted code execution in a serverless platform?▼

Securely isolate untrusted code execution by building sandboxes that enforce resource limits, filter system calls, and apply filesystem and network namespacing using Rust, C, and Python.

What does system call filtering do when sandboxing untrusted code?▼

System call filtering restricts the specific operations isolated code can perform, preventing external scripts from accessing sensitive user data or disrupting the host server environment.

How do I set up resource limits for untrusted Python scripts running on a web server?▼

Set up resource limits for untrusted Python scripts by configuring a secure sandbox that enforces strict boundaries on CPU, memory, and execution time to prevent server disruption.

Can I use filesystem and network namespacing for multi-tenant systems isolation?▼

Yes, you can use filesystem and network namespacing for multi-tenant systems isolation to create secure boundaries, preventing untrusted code from harming the host system or accessing resources.

Do I need a capability system to build sandboxes for browser plugins?▼

Yes, building sandboxes for browser plugins requires a capability system to manage isolation, enforce resource limiting, apply system call filtering, and configure filesystem and network namespacing.
