AZ-MEAS-01: vTPM boot measurements match the fleet's PCR baseline¶
| Property | Value |
|---|---|
| Severity | high |
| Platform | Hardware fleets (collector) |
| Lifecycle stage | hardware |
| Policy | P-09: Only signed images pinned to a measurement are launched |
| Evaluated from | Evidence sent to the service (collector bundles or registry scans), not from a cloud API scan. |
What it checks¶
It passes when:
- Quote signed by the attested vTPM key; PCRs … match the baseline.
How to fix¶
- Pin the PCR values of an approved boot (Environments → fleet policy) or investigate the changed boot component.
After the fix, scan again: the check should report PASS.
When it is not assessed¶
SKIP:
- Not assessed: the collector sent no vTPM quote (install tpm2-tools in the VM).
