CCSP · Question #236

Which of the following data protection methodologies maintains the ability to connect back values to the original values?

The correct answer is A. Tokenization. Tokenization is a data protection method that replaces sensitive data with a unique, non-sensitive identifier while retaining the ability to link back to the original value.

Why each option

Tokenization is a data protection method that replaces sensitive data with a unique, non-sensitive identifier while retaining the ability to link back to the original value.

ATokenizationCorrect

Tokenization replaces sensitive data with a unique identifier (token) that retains the ability to map back to the original data through a secure token vault or system, enabling reversible data protection. This reversibility is a key characteristic distinguishing it from other methods like anonymization.

BAnonymization

Anonymization irreversibly removes identifying information from data, making it impossible to link back to the original values.

CObfuscation

Obfuscation makes data difficult to understand but does not necessarily maintain a reversible link to the original values, often relying on complex algorithms rather than a direct mapping.

DDynamic mapping

Dynamic mapping is a general term that doesn't specifically refer to a data protection methodology designed for reversible value connection.
