LiteBox is a security-focused “library OS” sandboxing project that aims to shrink the interface between an application and its host environment to reduce attack surface. Instead of relying solely on broad OS-level permissions, it focuses on isolating workloads by tightly controlling the boundary where code interacts with host services and system resources. The design emphasizes interoperability across different integration layers, describing a separation between “North” shims (how apps or runtimes plug in) and “South” platforms (where the sandbox runs), which helps the system adapt to multiple deployment contexts. A key aspect of the project is that it targets both kernel-mode and user-mode scenarios, enabling experimentation with different trust and performance tradeoffs. The repository positions LiteBox as a foundation for building hardened execution environments where untrusted or semi-trusted components can run with reduced privileges and a minimized host interface.
Features
- Sandboxing library OS approach to reduce host attack surface
- Drastically minimized host interface for isolated workloads
- “North” shim integration model for plugging in runtimes and apps
- “South” platform abstraction for portability across execution environments
- Designed for both kernel-mode and user-mode usage scenarios
- Security-first architecture aimed at stronger isolation boundaries
