CAS-004 Security Engineering Practice Question
During a security audit, it was discovered that an HSM used for code signing is FIPS 140-2 Level 3 certified. The auditor is concerned about the key ceremony process. Which of the following is a required element of a secure key ceremony for an HSM at this level?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Keys are generated inside the HSM using a key ceremony with multiple officers
FIPS 140-2 Level 3 requires that cryptographic keys be created and stored in the HSM and never exist in plaintext outside the device. A key ceremony involves splitting keys into parts (m of n) and distributing them to multiple trusted individuals.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The HSM is configured to allow remote key backup over TLS
Why it's wrong here
Remote backup may expose keys.
- ✗
Keys are backed up to a USB drive stored in a safe
Why it's wrong here
Backups should also be encrypted and controlled.
- ✓
Keys are generated inside the HSM using a key ceremony with multiple officers
Why this is correct
This ensures keys never leave the HSM in plaintext.
- ✗
Keys are generated on a laptop and then imported into the HSM
Why it's wrong here
This would expose keys outside the HSM.
