Microsoft engineers, in collaboration with the Linux Virtualization Based Security (LVBS) project, have introduced LiteBox, a new open-source project designed to reduce the operating system's attack surface by limiting unnecessary access to system resources. LiteBox is described as "a security-focused library OS" that minimizes exposed interfaces while enabling flexible compatibility across platforms and execution environments.
LiteBox is a developer-facing technology and is not something users install directly. Instead, it is designed to be integrated into Windows apps, runtimes, or platform components.
