A cloud security architect is designing a highly secure environment for a financial services application that processes sensitive customer data. A key requirement is to ensure that all data, regardless of its location (in storage, in transit, or in use), is protected from unauthorized access or disclosure. Which overarching security concept does this requirement describe?
- AData Masking
- BData Minimization
- CData Tokenization
- DUbiquitous Data Encryption
Show answer & explanationAnswer & explanation
Correct answer: D. Ubiquitous Data Encryption
Ubiquitous Data Encryption refers to the concept of encrypting data at all stages of its lifecycle: at rest (in storage), in transit (over networks), and sometimes even in use (during processing within memory). This comprehensive approach ensures maximum protection against unauthorized access or disclosure.
Why the other options are wrong
- A. Data Masking obscures sensitive data for non-production environments, not universal protection across all states.
- B. Data Minimization is about collecting only necessary data, not how it's protected once collected.
- C. Data Tokenization replaces sensitive data with non-sensitive substitutes, typically for specific payment processing scenarios, not universal encryption.
Ubiquitous Data Encryption
The security concept of encrypting data at every point in its lifecycle: when it is stored (at rest), when it is moving across networks (in transit), and ideally, while it is being processed (in use).
- Provides end-to-end data protection
- Crucial for highly sensitive data and compliance
- Involves multiple encryption mechanisms
