ISC Risk Management Practice Question
You are assessing an Engineered System that utilizes a Trusted Platform Module (TPM) for secure boot. A scan reveals that the firmware version is outdated and susceptible to a known key-injection vulnerability. Which action should the ISSEP prioritize?
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
✓
Perform a firmware update using the manufacturer's signed secure update process.
Firmware vulnerabilities involving the TPM and secure boot chain represent a fundamental compromise of the root of trust. Remediation must prioritize the update of the firmware to restore the integrity of the secure boot sequence.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Update the security policy to include manual verification of boot logs.
Why it's wrong here
Manual logs are insufficient to address a hardware-level vulnerability in the secure boot chain.
- ✗
Configure an IDS to block unauthorized firmware update attempts.
Why it's wrong here
This does not address the vulnerability; it only monitors for malicious update attempts.
- ✗
Disable TPM-based secure boot until the vendor releases a patch.
Why it's wrong here
Disabling secure boot removes the system's primary protection against low-level malware.
- ✓
Perform a firmware update using the manufacturer's signed secure update process.
Why this is correct
Firmware updates are the only way to patch hardware-level vulnerabilities in the TPM/secure boot mechanism.
