Google Cloud Professional Cloud Security Engineer Practice Exam

Which encryption strategy is suitable for managing sensitive and non-sensitive data compliance?

1. Encrypt all data using custom keys

2. Encrypt non-sensitive data with Google default encryption

3. Encrypt all data with Cloud Key Management Service only

4. Store data without encryption for flexibility

The correct answer is: Encrypt non-sensitive data with Google default encryption

The selection of encrypting non-sensitive data with Google default encryption is suitable for managing compliance with sensitive and non-sensitive data for several reasons. First, using Google’s default encryption for non-sensitive data leverages a secure, standardized approach. Google Cloud automatically encrypts data at rest by default, which ensures that even without adding additional encryption mechanisms, the non-sensitive data is protected against unauthorized access. This is particularly beneficial for compliance, as it addresses the baseline security requirements often mandated by regulations and standards. Furthermore, this approach allows organizations to dedicate their resources towards implementing more rigorous encryption methods for sensitive data, which may require custom keys or specialized encryption strategies. By not over-encrypting non-sensitive data, organizations can maintain flexibility and efficiency, optimizing performance and managing costs without compromising compliance requirements. Proper use of encryption strategies, where sensitive data is given more robust protection while leveraging default security protocols for less critical data, is an effective way to balance compliance, security, and operational efficiency.
