CSPACE-INTEG-01: The current boot passed Shielded VM integrity monitoring¶
| Property | Value |
|---|---|
| Severity | high |
| Platform | GCP Confidential Space (AMD SEV-SNP) |
| Lifecycle stage | deploy |
| Mode | Passive: read-only cloud API calls. |
How to fix¶
- Find what changed in the boot chain (firmware, bootloader, kernel or Secure Boot keys). If the change was intended, update the integrity policy baseline (setShieldedInstanceIntegrityPolicy updateAutoLearnPolicy); if not, treat the instance as compromised and rebuild it.
After the fix, scan again: the check should report PASS.
When it is not assessed¶
SKIP:
- Need --gcp-instance, --gcp-zone, and --gcp-project; skipping check.
ERROR:
- Could not read instance config: …
