CompTIA Project+ (PK0-005)Basics of IT and GovernanceMedium
A project involves migrating a large volume of historical customer data to a new cloud-based data warehouse. The data contains personally identifiable information (PII) and needs to be protected both during transfer and when stored in the cloud. Which security consideration is paramount for protecting this data throughout its lifecycle in the cloud?
- AServer Uptime Guarantees
- BNetwork Latency Optimization
- CLoad Balancing
- DData Encryption
Show answer & explanationAnswer & explanation
Correct answer: D. Data Encryption
Data encryption is paramount for protecting sensitive data, especially PII, both in transit (during migration) and at rest (when stored in the cloud data warehouse). It renders the data unreadable to unauthorized parties.
Why the other options are wrong
- A. Server uptime guarantees address availability, not the confidentiality of the data itself.
- B. Network latency optimization focuses on speed, not data protection.
- C. Load balancing distributes traffic for performance and availability, not data security.
Data Encryption
The process of converting data into a coded format to prevent unauthorized access. It ensures data confidentiality and integrity both when data is in transit and at rest.
- Uses algorithms and keys to transform data.
- Essential for protecting sensitive information like PII.
- Commonly applied to databases, files, and network communications.
Memory trick: Encryption Keeps Everything Confidential.
