Show answer & explanationAnswer & explanation
Correct answer: D. Conducting a comprehensive data classification exercise to identify and label sensitive information.
Before any other control or agreement, understanding what data is sensitive and where it resides is fundamental. Data classification provides the necessary foundation for applying appropriate security controls and ensuring regulatory compliance.
Why the other options are wrong
- A. While important for third-party risk, data processing agreements rely on prior knowledge of the data's classification and sensitivity.
- B. Implementing an IDS is a technical control, but without understanding the data, its effectiveness in protecting sensitive information is limited.
- C. An incident response plan is crucial, but it's reactive; proactive understanding of data sensitivity must precede it.
Data Classification
The process of categorizing data based on its sensitivity, value, and regulatory requirements to determine appropriate protection measures.
- Foundation for data security policies.
- Enables compliance with privacy regulations.
- Helps prioritize security efforts.
Memory trick: Classify data first, then protect what you know.
