Frequently Asked Questions

This page includes answers to some frequently asked questions about Forseti Security.


Great! Please see the help page on how to submit your idea or get help.

Forseti documentation can be updated in the branch.

You can test your documentation changes locally, by following the instructions here.

After your updated documentation is merged, the Forseti team will merge it into the branch upon every major/minor release, which will trigger a new build of the website.

It depends on your setup:

  • If you want to be hands on, Forseti is a great solution to integrate into new or existing tooling.
  • If you want to be more hands free, Security Health Analytics is a great solution for a managed service.
Forseti Security Health Analytics
Customer deployed and managed Fully managed by GCP with SLA
Community support GCP support
Customizable auditing Comprehensive set of benchmarks (e.g. CIS certified)
Policy-as-code ecosystem (write the rules once,
and re-use them everywhere in your workflow)
Managed rules added by GCP
Real-time enforcement Scanning only
Basic integration with CSCC Deeper integrations with CSCC (reporting, dashboards, etc.)

Both services can be integrated with Cloud Security Command Center (CSCC) to receive notifications. Refer here for setting up Forseti to use CSCC.

Installation and deployment

For information about how to update Forseti to the latest release, see the Upgrade guide.

To correct mistakes in setup, edit your Forseti deployment script by Updating Forseti, or edit your Forseti configuration file by Configuring Forseti.

Following are the reasons you should run Forseti in a separate project:

  • Google Cloud Platform (GCP) API quota
    • Setting Forseti up in a separate project ensures that Forseti has the quota it needs for API calls and managing service accounts and roles.
  • Project permissions
    • Setting Forseti up in a separate project restricts who has access to your Forseti-related permissions and resources.
  • Forseti clean up
    • Setting Forseti up in a separate project allows you to easily clean up your Forseti-related data by deleting the project. Clean up includes the Compute Engine instance, Cloud SQL instance, Cloud Storage bucket, service accounts, and Cloud IAM policies.

If Forseti is reading data from only one project, your Forseti service account might have access only to that particular project. To get read access to all of the projects under your organization, add the service account to the organization’s Cloud IAM policy with the required roles. Your Organization Admin should be able to help you with that.

GCE VM instances have the unattended-upgrades tool to automatically update the operating system, software, or security patches from the Debian security repository.

However, kernel patches do not take effect until your VM instance is restarted. By default, GCE does not automatically restart running instances.So you must either restart your instances manually to update the kernel, or apply the mechanism provided by the unattended-upgrades tool to automatically do the restart.

Automatic updates from Debian security do not upgrade instances between major versions of the operating system. Debian also has a relevant guide:

Forseti is installed with the ubuntu account on the server VM. To update the cron job you need to SSH into the server VM and switch to the ubuntu user to update the cron job.

$ sudo crontab -u ubuntu -l # to see existing schedule
$ sudo crontab -u ubuntu -e # to edit cron schedule

Please follow the guidelines below, and the detailed steps in the referenced documentations, to install Forseti with internal IP only.

  • Prerequisites
  • Install Forseti
  • Configure Cloud SQL
    • enable internal IP
    • remove the external IP
  • Remove external IPs from the Forseti VMs
  • Firewall Rules: Depending on how your environment is setup, you’ll need to modify the firewall rules accordingly to allow SSH communication between the bastion host and Forseti VMs. A few suggestions:
    • Make sure the bastion host can access Forseti VMs
      • For example, create a tag-based rule allowing SSH connection between tag “bastion” and tag “forseti”, then tag the Forseti VMs and the bastion host as “forseti” and “bastion”, respectively
    • Modify firewall rules created by Forseti installer limiting them to the subnet instead of

You are all set! To verify it works, access the forseti VMs by connecting through a bastion host.

A few common causes if you cannot access Forseti VMs from the bastion host:

  • Your account does not have the appropriate permission
    • You might need to run to make sure gcloud could access your user credentials:
        gcloud auth login
  • Other firewall rules with higher priorities are blocking the SSH
  • Your metadata is not configured properly

Using Forseti

We have some starter documentation for defining rules. If you have more questions, you can ask for help at

By default, Forseti runs Inventory and Scanner every 2 hours at random minutes, using a simple cronjob. To change the cron value, edit the server’s deployment template.

The installation log is stored in /tmp/deployment.log on the Forseti Compute Engine instance. You can view it with any editor. For example:

vim /tmp/deployment.log

To find the Forseti Inventory, Scanner, and Enforcer logs:

  1. Go to the Google Cloud Platform Console Logs page.
  2. On the resources drop-down list, select GCE VM Instance.
  3. On the All logs drop-down list, select forseti.

You can implement bucket lifecycle rules to delete the output or migrate them to a lower cost class. You can also export the output to BigQuery.

  1. Follow the instruction here to add/change password of MySQL user root.

  2. ssh to the Forseti server VM.

  3. run command sudo vi /lib/systemd/system/forseti.service and you should see the following:

     Description=Forseti API Server
     ExecStart=/usr/local/bin/forseti_server --endpoint '[::]:50051' --forseti_db mysql://root@ --config_file_path /home/ubuntu/forseti-security/configs/forseti_conf_server.yaml --services explain inventory model scanner notifier
  4. Update the forseti_db flag to the following:

     Description=Forseti API Server
     ExecStart=/usr/local/bin/forseti_server --endpoint '[::]:50051' --forseti_db mysql://root:YOUR_PASSWORD@ --config_file_path /home/ubuntu/forseti-security/configs/forseti_conf_server.yaml --services explain inventory model scanner notifier
  5. Save and exit, run command sudo systemctl restart forseti to restart the forseti service and you should now be able to connect to the database with the password.

Security implications

Forseti uses a service account that is granted roles on the organization’s Cloud IAM policy. Because GCP roles are hierarchical, when someone has a Cloud IAM role at the organization level, child resources like folders and projects inherit the role. For example, if you grant the “Browser” role to someone at the organization level, they will also be able to see folders and projects within the organization.

For more information, see Service account for Forseti Security.

Because the Forseti service account needs many types of permissions to read certain data, you must grant grant Forseti the specific roles that it needs to do its job.
