    GCP PCA · Question 27 · Security Design

    Your company stores highly sensitive intellectual property in a Cloud Storage bucket. You need to ensure that even if an employee with legitimate IAM permissions tries to download the data from their home network or a coffee shop, the request is denied. How should you enforce this?

    Answer options:

    A.

    Remove the employee's IAM permissions when they leave the office.

    B.

    Implement VPC Service Controls and configure an ingress rule allowing access only from the corporate IP range.

    C.

    Configure a VPC Firewall rule to block port 443 from non-corporate IPs.

    D.

    Use Cloud Armor to block the employee's home IP address.

    How to approach this question

    Identify the service that provides context-aware access control for GCP APIs.

    Full Answer

    B.Implement VPC Service Controls and configure an ingress rule allowing access only from the corporate IP range.✓ Correct
    VPC Service Controls mitigates data exfiltration risks. It allows you to define a perimeter around services like Cloud Storage. Even if a user has valid IAM credentials, VPC SC will block the request if it doesn't meet the contextual rules (e.g., originating from a trusted corporate IP).

    Common mistakes

    Choosing VPC Firewall rules (C), which do not apply to Google APIs.
