Running Untrusted Code: Best Practices and Tools

TLDRLearn about the best practices and tools for running untrusted code, including virtual machines and containers. Understand the risks and benefits of each approach.

Key insights

Virtual machines provide the highest level of security by isolating untrusted code in separate VMs with their own kernels.

🐳Containers are a lightweight option for running untrusted code, but they share the same kernel and may have vulnerabilities.

🔒Additional isolation layers like Docker and gVisor help mitigate the risks of running untrusted code in containers.

Firecracker is a microVM manager developed by AWS that offers lightweight virtualization for running untrusted code.

⏱️Startup time and resource usage should be considered when choosing the right tool for running untrusted code.

Q&A

What is the most secure way to run untrusted code?

Using virtual machines provides the highest level of security by isolating untrusted code in separate VMs with their own kernels.

Are containers a secure option for running untrusted code?

Containers offer a lightweight solution for running untrusted code, but they share the same kernel and may have vulnerabilities. Additional isolation layers like Docker and gVisor can help mitigate these risks.

What is Firecracker?

Firecracker is a microVM manager developed by AWS that provides lightweight virtualization for running untrusted code. It offers a secure and scalable solution for running code in isolated environments.
