Google Cloud Professional Cloud Security Engineer Practice Exam

In a scenario where logs need PII detection, what is a practical approach to handle it?

1. Provide analysts with a manual access review process

2. Implement a filter mechanism before sharing the log data

3. Utilize Cloud Functions for automated PII scanning and handling

4. Share all logs with an additional warning notice

The correct answer is: Utilize Cloud Functions for automated PII scanning and handling

Utilizing Cloud Functions for automated PII scanning and handling represents a practical and efficient approach to address the need for PII detection in logs. Cloud Functions allows for serverless execution of code in response to specific events, making it an ideal tool for dynamically processing log data. In this scenario, a Cloud Function could be triggered whenever new log data is generated or ingested. This function can automatically scan the logs for any personally identifiable information (PII), such as names, email addresses, or social security numbers, using regular expressions or other scanning techniques. If any PII is detected, the function can take predetermined actions, like redacting or masking the sensitive information, logging the incident for compliance purposes, or even alerting administrators to the issue. This method is not only automated but also scalable, as it can handle varying volumes of logs without manual intervention. Automating the PII detection process reduces the risk of human error and ensures timely detection of sensitive information, which is crucial for compliance with data protection regulations like GDPR and CCPA. Furthermore, this approach integrates well within the Google Cloud ecosystem, utilizing existing cloud-native services to enhance security and efficiency.
