| Integrity | Varies by Context 注意：Security is lost if assets assumed to be immutable can be modified. |
潛在緩解措施
Phases : ImplementationStoring immutable code or data in read-only memory (ROM), fuses, or one-time programmable (OTP) memory provides strong integrity guarantees and provides a root of trust for securing the rest of the system.
