A security-focused library OS open-sourced by Microsoft
About
- A security-focused library OS that supports both kernel-mode and user-mode execution, providing a sandboxing environment that reduces the attack surface by minimizing the host interface
- Written in Rust; supports interoperation between nix- and rustix-style upper interfaces and various lower platforms
- Main use cases: running Linux programs on Windows, sandboxing Linux applications, running in SEV SNP and OP-TEE environments, LVBS platform support, etc.
- An experimental base for next-generation OS architecture focused on security isolation, virtualization, and minimizing the system interface
- Combines safe Rust-based system code with a unified kernel-user mode execution model; usable for security research and cloud isolation technology development
