Question
A company is developing an application that will be used to perform e-commerce transactions for a subscription-based service. The application must be able to use previously saved payment methods to perform recurring transactions. Which of the following is the most appropriate?
Options
- ATokenization through an HSM
- BSelf-encrypting disks with field-level encryption
- CNX/XN Implementation to minimize data retention
- DToken-based access for application users
- EAddress space layout randomization
Explanation
trying to connect a remote site to the central Tokenization through an HSM (Hardware Security Module) is the most appropriate solution for securely storing and using previously saved payment methods for recurring transactions. Tokenization replaces sensitive data (like credit card numbers) with a token, which is a non- sensitive equivalent that cannot be reversed without the corresponding HSM. This ensures that sensitive payment information is never stored in an accessible format and protects customer data from breaches while still enabling the application to perform transactions.
