LiteBox is a security-focused library OS from Microsoft that reduces attack surface by minimizing the host interface. It supports both kernel and user-mode execution with a modular architecture featuring "North" shims and "South" platforms. The library provides a Rust-based interface inspired by nix/rustix and enables use cases like running unmodified Linux programs on Windows, sandboxing Linux applications, executing on SEV SNP, and running OP-TEE programs. The project is under active development with APIs subject to change before stable release.

<p>Interesting approach. Reducing the host interface to lower attack surface makes a lot of sense, especially for sandboxing and running untrusted workloads more safely.</p>
