Signature Enforcement
Definition
Windows policy that verifies trust and integrity before kernel code loads.
Detailed explanation
Signature Enforcement is the Windows policy that verifies trusted signatures and file integrity before kernel code loads. Production signing, WHQL, attestation signing, test signing, HVCI, Secure Boot, and the vulnerable-driver blocklist are related but distinct controls. A trusted signature establishes provenance, not suitability for every device. Windows 10 and 11 production systems generally require Microsoft-trusted signing paths for new kernel drivers. Code Integrity event records distinguish policy and hash failures, while a vulnerable but correctly signed binary can still be blocked through revocation or security intelligence.
