CompTIA Security+ (SY0-601) — Question 355

Two organizations are discussing a possible merger. Both organizations' Chief Financial Officers would like to safely share payroll data with each other to determine if the pay scales for different roles are similar at both organizations. Which of the following techniques would be best to protect employee data while allowing the companies to successfully share this information?

Answer options

• A. Pseudo-anonymization
• B. Tokenization
• C. Data masking
• D. Encryption

Correct answer: A

Explanation

Pseudo-anonymization is the correct choice as it allows data to be shared without revealing the identities of individuals, which is essential for protecting employee information. Tokenization and encryption are also valid methods of data protection, but they do not allow for the same level of data usability and comparison as pseudo-anonymization. Data masking alters the data, which may prevent accurate comparisons of pay scales.
