Objective: Ensure only front-end Compute Engine instances have public IPs, while others do not.

Solution: Use an organization policy to enforce this requirement.

Steps:

Step 1: Open the Google Cloud Console.

Step 2: Navigate to the Organization Policies page.

Step 3: Create a new policy with the constraint constraints/compute.requireOsLogin (or similar constraint to manage public IPs).

Step 4: Define the conditions to allow public IPs only for the front-end instances.

Step 5: Apply the policy to the organization or specific projects as necessary.

By setting up an organization policy with specific conditions, you can control which instances are allowed to have public IPs based on their role or other attributes.

To enable developer teams to deploy new applications without the extensive overhead of network and security reviews, it’s recommended to mandate the use of infrastructure as code (IaC) and enforce policies through static analysis in CI/CD pipelines. This approach ensures that security and compliance policies are checked automatically during the development process.

Step-by-Step:

Adopt IaC: Use tools like Terraform or Google Cloud Deployment Manager to manage infrastructure as code.

CI/CD Pipeline Integration: Integrate static analysis tools such as TFLint or Checkov in the CI/CD pipeline to enforce security policies.

Policy Definition: Define security policies and best practices that need to be adhered to in the code.

Automated Checks: Configure automated checks in the CI/CD pipeline to review code against these policies before deployment.

Monitor and Audit: Continuously monitor and audit deployed applications to ensure ongoing compliance.

To keep track of "who did what, where, and when?" within GCP projects, the administrator should focus on Admin Activity logs and Data Access logs. Here’s a detailed explanation of why these two log streams are essential:

Admin Activity Logs:

These logs capture administrative actions performed in your Google Cloud resources. This includes actions like creating, modifying, or deleting resources.

Admin Activity logs provide detailed information about the user who performed the action, the resource that was affected, the action performed, and the timestamp.

Data Access Logs:

These logs capture read and write operations on data within your Google Cloud services. This includes actions like accessing or modifying data stored in databases, storage buckets, etc.

Data Access logs help track the access patterns of users and services to sensitive data, providing insights into who accessed which data and when.

Steps to Enable and Access Logs:

Navigate to the Google Cloud Console.

Go to Logging in the left-hand menu.

Enable Admin Activity and Data Access logs if not already enabled.

Use Logs Explorer to filter and view specific logs based on your requirements.

By monitoring both Admin Activity and Data Access logs, administrators can gain comprehensive visibility into the actions performed on their GCP resources and data, ensuring robust security and compliance tracking.

An API bundle:

All APIs (all-apis): most Google APIs

(same as private.googleapis.com).

VPC-SC (vpc-sc): APIs that VPC Service Controls supports

(same as restricted.googleapis.com).

VMs in the same VPC network as the endpoint (all regions)

On-premises systems that are connected to the VPC network that contains the endpoint

To ensure that application teams can only add users from within your organization to their groups, you need to configure the group settings in the Google Workspace Admin console. Here are the steps:

Access Google Workspace Admin Console:

Go to the Google Workspace Admin console.

Navigate to the Groups section.

Configure Group Settings:

Select the relevant groups used by the application teams.

Go to the group settings and set the group to only allow members from your domain.

This prevents external users from being added to these groups.

Apply and Save Changes:

Apply the changes to ensure that only users from within your organization can be added to these groups.

Verify Configuration:

Test the configuration by attempting to add an external user to the group and verifying that it is not allowed.

Benefits:

Security: Prevents unauthorized access by ensuring that only internal users can be added to groups.

Compliance: Helps in adhering to organizational policies regarding user access and management.

Managing IAM permissions at the KeyRing level is more efficient and scalable compared to managing them at the individual Key level. By creating a single KeyRing and placing all encryption keys within it, you can apply uniform IAM permissions to the entire KeyRing, simplifying the management of permissions.

Steps:

Create a KeyRing: Set up a single KeyRing in Cloud KMS for all the encryption keys required for the persistent disks.

Create Encryption Keys: Generate the necessary encryption keys within this KeyRing.

Set IAM Permissions: Assign IAM roles and permissions to the KeyRing to manage access control at this level, ensuring that all keys within the KeyRing inherit these permissions.

To identify all principals who can change firewall rules, you need to determine which users or service accounts have permissions that allow them to modify firewall rules in your Google Cloud project. The correct permissions to check for this are compute.firewalls.create and compute.firewalls.delete. These permissions enable a user to create and delete firewall rules, respectively.

The Policy Analyzer tool in Google Cloud allows you to query and analyze IAM policies to identify which principals have specific permissions. By using Policy Analyzer, you can effectively identify all principals with the compute.firewalls.create and compute.firewalls.delete permissions.

Open Policy Analyzer: Go to the Google Cloud Console, navigate to IAM & Admin, and select Policy Analyzer.

Set Up Query: Create a new query specifying the permissions compute.firewalls.create and compute.firewalls.delete.

Run Query: Execute the query to retrieve a list of principals who have these permissions.

Review Results: Analyze the results to identify all users and service accounts with the capability to modify firewall rules.

This method ensures you have a comprehensive list of all principals who can change firewall rules, enhancing your audit and security posture.
