What is TPM Event Log?
Quick note explaining TPM Event Log for BIOS/UEFI and embedded firmware readers.
What is TPM Event Log?
TPM Event Log is a UEFI firmware security concept related to boot trust, variable protection, measurement, or firmware update policy.
Why it matters
- Explains advanced firmware-security mechanisms.
- Helps reason about trust anchors, measurements, and update protection.
- Useful for security-focused BIOS/UEFI analysis.
Practical example
Example: when debugging image authentication, check whether the signer is trusted by db and whether the image hash or certificate is blocked by dbx.
Quick checklist
- Which trust anchor or measurement path is involved?
- Does the policy match the platform state?
- Can the behavior be confirmed from logs, variables, or TPM event data?
Quick takeaway
TPM Event Log is a small concept, but it often becomes important when reading logs or debugging real firmware.
