CompTIA CASP CAS-004 Question # 68 Topic 8 Discussion

If the asymmetric private key defined in the write-once read-many (WORM) portion of the System on Chip (SoC) is compromised, the IoT device manufacturer cannot simply replace or update the key through software changes due to the nature of WORM memory. The compromised key would necessitate the production of a new IoT device with a redesigned SoC that includes a new, secure private key. This is because the integrity of the encryption module is fundamental to the device's security, and a compromised key cannot be allowed to persist in the hardware.
