The article highlights a critical gap in enterprise security infrastructure: while Trusted Platform Modules (TPMs) are ubiquitous in servers and cloud VMs for measured boot, there's no public database of known-good TPM measurements to verify system integrity at scale. This verification gap makes it impossible to effectively validate what software actually booted across large fleets, despite TPMs being a 20-year standard. The author explains how PCR values work and why the lack of verification infrastructure undermines remote attestation in practice.
Background
Trusted Platform Modules (TPMs) are security chips that measure system boot integrity through Platform Configuration Registers (PCRs) and provide remote attestation capabilities. They are standard in enterprise hardware and cloud VMs but lack critical verification infrastructure.
