Which term describes the process of verifying hardware provenance to ensure it originates from trusted sources?

• A. Trusted Foundry
• B. Port Security
• C. CAM Table
• D. Source Authenticity

Answer: (D)

Verifying hardware provenance to ensure it comes from trusted sources is all about confirming the origin and trustworthiness of the component. This is what source authenticity covers: you check that a piece of hardware действительно came from a known, trusted manufacturer and hasn’t been substituted or tampered with in transit. In practice, this can involve supplier attestations, cryptographic certificates, and hardware attestation that verify provenance along the supply chain.

A trusted foundry relates to the secure environment where components are manufactured, which is connected but different from the act of verifying a specific item’s origin. Port security focuses on preventing unauthorized devices from connecting to a network port, not on proving where a hardware piece originated. The CAM table is simply the switch’s record of which MAC addresses are reachable on which ports, and it isn’t about provenance at all.
