kernel isolation

About this tag
Discussions tagged with kernel isolation on WindowsForum.com focus on Microsoft's efforts to reduce the attack surface of the Windows kernel and strengthen system security. Topics include LiteBox, a Rust-based library OS that minimizes kernel exposure for applications, and Virtualization-Based Security (VBS) enclaves, which isolate sensitive processes. A critical vulnerability (CVE-2025-47159) in VBS enclaves is also covered, highlighting risks to this isolation mechanism. Additionally, Microsoft's work on reducing reboot requirements for updates is discussed, as it relates to kernel-level changes that enable live patching. These threads explore how kernel isolation techniques protect against exploits and improve overall system integrity.
