Review Admin Activity logs:

Admin Activity logs contain entries for API calls that modify or read the configuration or metadata of resources.

These logs are useful for monitoring and auditing administrative actions, including those that could indicate malicious activity on a Cloud SQL instance.

Using Identity-Aware Proxy (IAP) for managing SSH access to private VMs ensures secure access control and avoids the need for public IPs. IAP allows you to enforce identity-based access control policies.

Enable IAP: Ensure that IAP is enabled for your project. This can be done via the Google Cloud Console under "Security" -> "Identity-Aware Proxy".

Set Up Firewall Rule: Create a firewall rule to allow SSH traffic from the IAP IP ranges.

Navigate to "VPC network" -> "Firewall".

Create a new rule allowing ingress traffic on port 22 (SSH) from the IAP IP ranges.

Assign IAP-Secured Tunnel User Role: Grant the roles/iap.tunnelResourceAccessor role to the administrators who need SSH access.

Go to "IAM & Admin" -> "IAM".

Assign the IAP-Secured Tunnel User role to the relevant users or groups.

SSH Using IAP: Administrators can now use IAP to SSH into the instances. This can be done using the gcloud command:

gcloud compute ssh [INSTANCE_NAME] --tunnel-through-iap

Objective: Create a Service Account that can list Compute Engine instances in the project following Google-recommended practices.

Solution: Create a custom role and assign it to the Service Account.

Steps:

Step 1: Open the Google Cloud Console.

Step 2: Navigate to the IAM & Admin page and select "Roles".

Step 3: Click on "Create Role" and define a new role with a suitable name and description.

Step 4: Add the permission compute.instances.list to the custom role.

Step 5: Save the custom role.

Step 6: Go to the "Service Accounts" section.

Step 7: Create a new Service Account or select an existing one.

Step 8: Assign the newly created custom role to the Service Account.

By creating a custom role with the specific permission to list Compute Engine instances, you follow the principle of least privilege, which is a recommended security practice.

Objective: Implement an encryption at-rest strategy that balances key management complexity and control for sensitive and non-sensitive data, ensuring FIPS 140-2 L1 compliance.

Solution: Use Google default encryption for non-sensitive data and Cloud Key Management Service (KMS) for sensitive data.

Steps:

Step 1: Store non-sensitive data using Google Cloud’s default encryption, which automatically encrypts data at rest without additional configuration.

Step 2: For sensitive data, use Cloud KMS to create and manage encryption keys.

Step 3: Configure key rotation policies for the keys managed by Cloud KMS to meet compliance requirements.

Step 4: Ensure that all data encryption keys used by Cloud KMS comply with FIPS 140-2 Level 1 standards.

By using Google default encryption for non-sensitive data and Cloud KMS for sensitive data, you can manage encryption efficiently while maintaining control over key residency and rotation for sensitive data.

To migrate the current data backup and disaster recovery solutions to GCP while keeping the production environment on-premises, the most scalable and cost-efficient solution is using Google Cloud Storage with scheduled tasks and the gsutil command.

Setup Cloud Storage: Create a Cloud Storage bucket to store the backups.

Go to the Cloud Console and navigate to Cloud Storage.

Click "Create bucket" and follow the prompts to configure the storage bucket.

Install gsutil: Ensure gsutil is installed on the on-premises servers.

gsutil is a command-line tool for interacting with Cloud Storage.

Follow the installation guide here.

Create Backup Script: Write a script to upload data to Cloud Storage using gsutil.

#!/bin/bash gsutil -m cp -r /path/to/local/backup gs://your-bucket-name

Schedule Backup Task: Use a scheduling tool like cron on Linux to run the backup script at regular intervals.

Edit the crontab file with crontab -e and add an entry like:

Access Google Cloud Console:

Log in to the Google Cloud Console with administrative privileges.

Navigate to the "IAM & Admin" section.

Set Session Length Timeout:

Go to the "Settings" page within IAM & Admin.

Locate the "Session control" settings.

Configure the session length timeout to a shorter duration, such as 15 or 30 minutes. This ensures that user sessions expire automatically after the specified time of inactivity.

Apply and Enforce the Policy:

Save the changes and ensure the new session timeout policy is applied across all users and services.

Communicate the new policy to employees, highlighting the importance of session security and the rationale behind the change.

Additional Security Measures:

Consider implementing additional measures such as automatic screen locks and secure session management practices.

Educate employees on the importance of logging out of their sessions and securing their devices when not in use.

Session Management Best Practices

To enforce private connectivity between on-premises hosts and Google Cloud APIs while optimizing for cost and operational efficiency, using a dedicated or Partner Interconnect is the best solution. This setup ensures a reliable, high-bandwidth connection with private IP addressing.

Choose Interconnect Type: Decide between Dedicated Interconnect and Partner Interconnect based on your bandwidth needs and proximity to Google Cloud locations.

Set Up Interconnect:

For Dedicated Interconnect, order circuits through the Google Cloud Console.

For Partner Interconnect, select a supported service provider and order the connection through them.

Configure VPC and Private Google Access:

In your VPC, enable Private Google Access to allow on-premises hosts to access Google APIs privately.

Go to "VPC network" -> "Private Google Access" and enable it for your subnets.

Establish Connectivity: Work with your network team and (if applicable) your Partner Interconnect provider to set up the physical and logical connections.

Test Connectivity: Verify that on-premises hosts can reach Google Cloud services using private IP addresses.

This approach allows you to expose the web interface securely by using Identity-Aware Proxy (IAP), which provides authentication and authorization with Google credentials. The HTTP Load Balancer can distribute traffic to the VMs in the managed group, and the VPC firewall rule ensures that access is allowed from the IAP network range.
