ISC Practice Question: Systems Security Implementation Verification And Validation
When validating a secure boot implementation on a server, which component should be verified in the UEFI firmware settings?
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
✓
Verify that 'Secure Boot' is set to 'Enabled' and the 'Platform Key' (PK) is installed.
Secure Boot validation requires ensuring the UEFI firmware is set to enforce digital signatures on bootloaders.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Validate the TPM version is 2.0.
Why it's wrong here
A TPM is required for Measured Boot, but Secure Boot is a distinct UEFI feature.
- ✗
Check that 'Legacy Boot' is set to 'Disabled'.
Why it's wrong here
While recommended, this is not the core component of Secure Boot itself.
- ✓
Verify that 'Secure Boot' is set to 'Enabled' and the 'Platform Key' (PK) is installed.
Why this is correct
Secure Boot relies on the PK to establish the trust chain for the firmware and OS bootloader.
- ✗
Ensure the system clock is synchronized with a secure NTP server.
Why it's wrong here
This is important for logs and time-stamping, not Secure Boot.
