Certified Information Systems Security Professional (CISSP) — Question 346

A database server for a financial application is scheduled for production deployment. Which of the following controls will BEST prevent tampering?

Answer options

• A. Data sanitization
• B. Data validation
• C. Service accounts removal
• D. Logging and monitoring

Correct answer: B

Explanation

Data validation is crucial as it ensures that the data being inputted into the database meets specific criteria, thus reducing the risk of tampering. While data sanitization and service account removal are important for other security aspects, they do not directly address the integrity of data inputs. Logging and monitoring are useful for detecting tampering after it occurs but do not prevent it in the first place.
