What information can be found by dumping data at rest from a Purdue Enterprise Reference Architecture level 0/1 device?

Suggested Answer: C Vote an answer

Level 0 and Level 1 devices in the Purdue model include sensors, actuators, and controllers such as PLCs.
Dumping data at rest from these devices often reveals static cryptographic keys (C) stored within device memory or configuration files.
Firmware on read-protected chips (A) is generally inaccessible without specialized hardware attacks.
Frequency-hopping algorithms (B) pertain to wireless devices and are typically secured and not directly stored in the general memory dump.
GICSP stresses the risk of key compromise from device data extraction as it can enable unauthorized control or decryption of communications.
