Professional-Cloud-Security-Engineer Exam Dumps - Google Cloud Certified - Professional Cloud Security Engineer

Assured Workloads for Google Cloud allows you to deploy regulated workloads with data residency, access, and support requirements. It helps you configure your environment in a manner that aligns with specific compliance frameworks and standards.

To ensure that PII data is separated from non-PII data, using Cloud Pub/Sub and Cloud Functions to trigger a scan by the Data Loss Prevention (DLP) API is an effective approach. This method allows for automated detection and handling of PII.

Steps:

Set Up Cloud Pub/Sub: Configure a Cloud Pub/Sub topic to receive notifications whenever a file is uploaded to the shared Cloud Storage bucket.

Deploy Cloud Functions: Create a Cloud Function that is triggered by the Pub/Sub topic. This function will invoke the DLP API to scan the uploaded file for PII.

Move Detected PII Files: If the scan detects PII, the Cloud Function will move the file to a secure Cloud Storage bucket accessible only by the administrator.

Set Permissions: Ensure that appropriate permissions are set on the Cloud Storage buckets to restrict access to files containing PII.

Define Trusted Image Projects:

Identify the project or projects where your trusted operating system images are stored.

Ensure these images meet your organization’s security requirements and are regularly updated to mitigate vulnerabilities.

Create an Organization Policy:

Navigate to the Organization Policies page in the Google Cloud Console.

Create a policy constraint that restricts the creation of boot disks to only those images stored in your trusted image project(s).

The policy constraint to use is constraints/compute.trustedImageProjects.

Apply the Policy:

Apply this organization policy at the appropriate level (organization, folder, or project) to enforce that all new VM instances use images from the trusted repository.

This ensures consistency in the security posture across all projects within the organization.

Monitor Compliance:

Regularly monitor the compliance with this policy using audit logs and other monitoring tools.

Update the trusted images as necessary to ensure they remain secure and compliant with your security standards.

Trusted Image Projects Constraint

This approach allows you to control network traffic at the folder level. By attaching external IP addresses to the VMs in scope, you can ensure that the VMs have a unique, routable IP address for outbound connections. Then, by defining and applying a hierarchical firewall policy at the folder level, you can enforce that egress connections are limited to the specified IP range and only from the specified VPC network.

Objective: Implement external web application protection and validate policy changes before enforcement.

Solution: Use Google Cloud Armor's preconfigured rules in preview mode.

Steps:

Step 1: Open the Google Cloud Console.

Step 2: Navigate to the Google Cloud Armor section.

Step 3: Create or select a security policy.

Step 4: Apply preconfigured rules to the policy.

Step 5: Enable preview mode to simulate the effects of the rules without enforcing them.

Step 6: Monitor the logs to validate the policy changes.

Google Cloud Armor's preview mode allows you to test and validate the impact of security policies on your application traffic before applying them, ensuring that they work as intended without disrupting the service.

Scenarios for exporting Cloud Logging data: Splunk This scenario shows how to export selected logs from Cloud Logging to Pub/Sub for ingestion into Splunk. Splunk is a security information and event management (SIEM) solution that supports several ways of ingesting data, such as receiving streaming data out of Google Cloud through Splunk HTTP Event Collector (HEC) or by fetching data from Google Cloud APIs through Splunk Add-on for Google Cloud. Using the Pub/Sub to Splunk Dataflow template, you can natively forward logs and events from a Pub/Sub topic into Splunk HEC. If Splunk HEC is not available in your Splunk deployment, you can use the Add-on to collect the logs and events from the Pub/Sub topic. https://cloud.google.com/solutions/exporting-stackdriver-logging-for-splunk

Cloud Data Loss Prevention API allows to detect and redact or remove sensitive data before the comments or reviews are published. Cloud DLP will read information from BigQuery, Cloud Storage or Datastore and scan it for sensitive data.

"To support common use cases like setting a Time to Live (TTL) for objects, retaining noncurrent versions of objects, or "downgrading" storage classes of objects to help manage costs, Cloud Storage offers the Object Lifecycle Management feature. This page describes the feature as well as the options available when using it. To learn how to enable Object Lifecycle Management, and for examples of lifecycle policies, see Managing Lifecycles." https://cloud.google.com/storage/docs/lifecycle
