Boot integrity is the assurance that a system started using expected, authorized, and untampered startup components. It matters because early compromise can undermine everything that depends on the operating system starting from a trustworthy state.
What is Boot Integrity?
Boot integrity depends on trusted firmware, verified startup components, strong signing practices, and often hardware-backed measurement or verification. It is central to modern endpoint trust and resistance against low-level persistence attacks.
What Boot Integrity Commonly Supports
Common uses include endpoint hardening, trusted device enrollment, rootkit resistance, attestation, and secure operating-system startup.
Boot Integrity vs. Compromised Startup Path
Boot integrity means startup components are expected and trustworthy. A compromised startup path allows hidden low-level persistence or tampering before normal defenses engage.
Frequently Asked Questions
Why is boot integrity important?
Because security controls are much weaker if the platform beneath them starts in an untrusted state.
How is boot integrity strengthened?
Through Secure Boot, Measured Boot, firmware protection, signed updates, and hardware-backed trust roots.
