CCSP Practice Question: A cloud security team is implementing…
A cloud security team is implementing tokenization for a payment system. Which THREE statements correctly describe tokenization characteristics?
⚠ Common exam trap
ISC2 often tests the misconception that tokenization is a form of encryption, but the key distinction is that tokenization uses a lookup table (vault) rather than a mathematical algorithm, making it non-reversible without vault access.
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
✓
The original sensitive data is stored in a secure token vault.
Tokenization replaces sensitive data (e.g., credit card numbers) with a token, and the original data is stored securely in a token vault. This vault is isolated and access-controlled, ensuring that only authorized systems can detokenize the data when needed. The vault is the authoritative source for mapping tokens back to original values, which is fundamental to tokenization's security model.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Tokenization uses encryption algorithms to protect data.
Why it's wrong here
Incorrect: Tokenization does not use encryption; it is a substitution.
- ✓
The original sensitive data is stored in a secure token vault.
Why this is correct
Correct: The mapping between token and original data is stored in a vault.
- ✓
The token is a randomly generated string with no mathematical relationship to the original data.
Why this is correct
Correct: Tokens are generated randomly and are not reversible.
- ✓
Tokens can be used for transactions without exposing the original data.
Why this is correct
Correct: Tokens are used in place of sensitive data for processing.
- ✗
Tokenization is reversible using the token alone.
Why it's wrong here
Incorrect: Tokenization requires access to the token vault to detokenize.
