Microsoft has announced Litebox, an open source “security-focused library OS supporting kernel- and user-mode execution.”

According to the project page, “LiteBox is a sandboxing library OS that drastically cuts down the interface to the host, thereby reducing attack surface.”

LiteBox, which is written in Rust and developed under the MIT license, is designed for use in both kernel and non-kernel scenarios, with example use cases including:

• Running unmodified Linux programs on Windows
• Sandboxing Linux applications on Linux

The LiteBox team is currently working toward a stable release and notes that some APIs and interfaces may change as development continues. Learn more from the GitHub page.
