Guide: Understanding and Answering Questions on Data Privacy

Data Privacy: It refers to the aspect of information technology (IT) that deals with the ability an organization or individual has to determine what data in a computer system can be shared with third parties.

Importance:
Data privacy is crucial as it underpins the realization of the full potential of data-driven innovation while maintaining the trust of consumers, especially in a world where data breaches are increasingly common.

How it works:
Data Privacy works by implementing strong policies, rules, and measures to safeguard the data from theft, misuse, unauthorized access, disclosure, alteration, and destruction. This includes methods like encryption, pseudonymization, data access controls, and data masking.

Exam Tips - Answering Questions on Data Privacy:
1. Understand the Concepts: Have a comprehensive understanding of what data privacy is, its importance, and how it works.
2. Application is Key: Examiners often look for candidates' understanding of the application of concepts and principles. Thus, be ready to answer questions that probe your capacity to apply these principles and practices to given situations.
3. Key Legislations: Understand the key legislations guiding data privacy like GDPR (General Data Protection Regulation), and know the penalties for non-compliance.
4. Familiarize with Privacy by Design: Know and understand the concept of 'Privacy by Design' (PbD).
5. Practice Past Questions: Familiarize yourself with past questions to understand the pattern and style of how questions can come. This can significantly boost your confidence during the exam.

Question 1

A company is migrating to cloud storage for their employees' personal files. Which of the following encryption methods will BEST protect their data privacy?

Server-side encryption Polymorphic encryption Client-side encryption Metamorphic encryption

Correct Answer: Client-side encryption

Client-side encryption allows data to be encrypted locally on the user's device before it's transferred to the cloud storage. This ensures that only the user who encrypted the data can access it, providing maximum data privacy. Server-side encryption, in-transit encryption, and at-rest encryption deal with different stages of data storage, while metamorphic and polymorphic encryption are not actual encryption methods.

Question 2

An employee of a healthcare organization was recently caught selling patients' personal information. Which of the following methods would have BEST protected the patient data?

Device encryption Segmentation Intrusion Prevention System (IPS) Data anonymization

Correct Answer: Data anonymization

Data anonymization is the process of removing or obscuring personally identifiable information (PII) from data sets, ensuring both data privacy and compliance with regulations. Device encryption, segmentation, IPS, 2FA, and VPN are all useful security measures, but they don't address the specific issue of protecting patient data from unauthorized disclosure by an insider.

Question 3

A company recently discovered malware exfiltrating sensitive customer data. Which of the following privacy controls should be implemented to prevent future occurrences?

Endpoint Detection and Response (EDR) SSL/TLS certificate Network-based Intrusion Detection System (NIDS) Data Loss Prevention (DLP)

Correct Answer: Data Loss Prevention (DLP)

Data Loss Prevention (DLP) is the most effective privacy control to prevent sensitive customer data exfiltration. DLP monitors data movement across the network and prevents unauthorized data transmission. Other suggested options such as EDR, NIDS, SSL/TLS certificates, WAF, and APM are useful for different purposes, but they don't offer the specific data exfiltration prevention that a DLP solution provides.
