ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

A payment application must reduce PCI DSS scope and limit the value of stolen card records. Architects will store tokens in the main database, replacing each primary account number (PAN), while a separate vault maps tokens to real PANs. Which tokenization characteristic most directly achieves this risk reduction?

  • Tokenization works by applying format-preserving encryption, so authorized systems can derive the PAN on demand.

  • Each token is a random value with no mathematical link to the PAN, so it is useless without the secure mapping service.

  • Tokens contain an embedded checksum that allows systems to verify and reconstruct the PAN when needed without a vault.

  • Tokens are encrypted PANs created with long symmetric keys, making brute-force attacks computationally infeasible.

Random Mixed
Questions are selected randomly from all chosen topics, with a preference for those you haven’t seen before. You may see several questions from the same objective or domain in a row.
Rotate by Objective
Questions cycle through each objective or domain in turn, helping you avoid long streaks of questions from the same area. You may see some repeat questions, but the distribution will be more balanced across topics.

Check or uncheck an objective to set which questions you will receive.
