CRISC Information Technology and Security Practice Question
A risk manager is assessing the potential impact of quantum computing on the organization's cryptographic infrastructure. What is the MOST immediate action the organization should take?
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
✓
Conduct a cryptographic inventory to identify vulnerable systems
The first step is to inventory all cryptographic systems to understand where quantum-vulnerable algorithms are used, enabling a migration plan.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Purchase quantum-resistant hardware security modules
Why it's wrong here
Premature without understanding requirements.
- ✓
Conduct a cryptographic inventory to identify vulnerable systems
Why this is correct
Knowing the current state is essential for planning.
- ✗
Immediately replace all encryption with post-quantum algorithms
Why it's wrong here
Post-quantum algorithms are still being standardized; immediate replacement may not be possible.
- ✗
Discontinue use of public key cryptography
Why it's wrong here
Not feasible as many systems rely on it.
