Before you start
The setup involves:
Creating a project to contain a service account key
Creating a service account inside the project, and an associated key
Giving the service account Viewer and Service Auditor access to the client's organisation
Enabling APIs required for scanning
These must be enabled on the project that contains the service account
Adding the integration in Portal using the service account key
For existing clients who have already configured the Google Cloud Integration using the old service account instructions, the differences are:
OAuth is no longer available
We recommend creating a new project to host the service account
This isn't strictly necessary, but it's recommended because APIs must be enabled on the project. Additionally, it will result in a cleaner setup.
The permissions are set up on the organisation level, not the project level
You can restrict access to specific projects by setting up the required permissions on the project or folder level. To ensure full coverage, though, we recommend configuring these permissions at the organisation level instead.
We ask for
ViewerandSecurity Auditorroles instead ofCompute Network ViewerandDNS ReaderSeveral APIs must be enabled.
Step 1 - Setting up Google Cloud
There are two different options available for setting up the Service Account - please find links to each of these below:
Option A - Using gcloud CLI
1. Ensure you're authenticated:
gcloud auth login
2. Create a project to contain the service account"
👉 It's recommended to use a standalone project that contains the permissions we need for cloud security scans instead of reusing an existing project.
First, get the ID of your organisation:
gcloud organizations list
ORGANIZATION_ID=<copy your organization ID here>
Then create a project:
PROJECT_ID="intruder-connector-$(date +%s)"
gcloud projects create $PROJECT_ID --organization=$ORGANIZATION_ID
3. Create a service account:
SA_NAME="intruder-connector-$(date +%s)"
gcloud iam service-accounts create $SA_NAME --project=$PROJECT_ID --display-name="Intruder Connector"
4. Create a key file for the service account:
gcloud iam service-accounts keys create "./${SA_NAME}-key.json" --iam-account="${SA_NAME}@${PROJECT_ID}.iam.gserviceaccount.com" --project=$PROJECT_ID👉 You will need to upload the key file to Intruder when connecting your account.
The service account key is confidential. Please store it securely following the best practices outlined here:
5. Add the Viewer and Security Auditor roles across your organisation for the service account:
gcloud organizations add-iam-policy-binding $ORGANIZATION_ID \
--member="serviceAccount:${SA_NAME}@${PROJECT_ID}.iam.gserviceaccount.com" \
--role="roles/viewer"
gcloud organizations add-iam-policy-binding $ORGANIZATION_ID \
--member="serviceAccount:${SA_NAME}@${PROJECT_ID}.iam.gserviceaccount.com" \
--role="roles/iam.securityAuditor"
6. Finally, enable APIs that we use to scan your projects for vulnerabilities
👉 Setting a billing account is required by Google for enabling some of the APIs we use to scan your projects. We use read-only access to those APIs and will never incur any charges to your account.
First, select a billing account to link to the project containing your service account:
gcloud billing accounts list
BILLING_ACCOUNT_ID=<insert the billing account's ACCOUNT_ID here>
Link your project to the billing account:
gcloud billing projects link $PROJECT_ID --billing-account=$BILLING_ACCOUNT_ID
Enable the APIs:
gcloud services enable \
--project=$PROJECT_ID \
serviceusage.googleapis.com \
cloudresourcemanager.googleapis.com \
sqladmin.googleapis.com \
iam.googleapis.com \
apikeys.googleapis.com \
accessapproval.googleapis.com \
essentialcontacts.googleapis.com \
cloudkms.googleapis.com \
bigquery.googleapis.com \
logging.googleapis.com \
compute.googleapis.com \
container.googleapis.com \
dns.googleapis.com \
storage.googleapis.com \
cloudasset.googleapis.com
Option B - Using the Google Cloud web console
1. Log in to console.cloud.google.com
2. Open the project picker in the top left navigation menu
3. Create a new project to contain the service account by clicking New project.
👉 It's recommended to use a standalone project that contains the permissions we need for cloud security scans instead of reusing an existing project
Give the project a name, select a billing account, and click
Create:
👉 Setting a billing account is required by Google for enabling some of the APIs we use to scan your projects. We use read-only access to those APIs and will never incur any charges to your account.
Open the project picker again
4. Select the newly created project
5. In the top navigation, search for Service accounts and navigate as shown
6. Click Create service account
7. Give the service account a name (here Intruder connector), note down the Service account ID and click Done
8. In the service account list, click on the newly created service account:
9. Note down the value in the Email field in the Details tab:
10. Open the Keys tab, and click on Add Key → Create new key
11. Select the JSON type and click on Create
12. The service account key is automatically downloaded to your computer. You will need to upload the file to Intruder when connecting your account.
Note: the service account key is confidential. Store it securely following the best practices outlined here: https://cloud.google.com/iam/docs/best-practices-for-managing-service-account-keys#credential-leakage
13. Open the project picker again, and select your organisation:
14. In the left navbar, select the IAM link:
15. In the View by principals tab, click on Grant access
16. In the Add principals field, enter the service account's Email from step 9, and in Assign roles, add the Basic → Viewer role. Then click Add another role, search for Security Auditor, add the Security Auditor role and click Save.
17. Open the project picker again, and select the project containing your service account. This is important, as the APIs must be enabled on this project in order to enable us to scan all your projects.
18. Finally, enable APIs that we use to scan your projects for vulnerabilities:
Service Usage APICloud Resource Manager APICloud SQL Admin APIIdentity and Access Management (IAM) APIAPI Keys APIAccess Approval APIEssential Contacts APICloud Key Management Service (KMS) APIBigQuery APICloud Logging APICloud Asset APICompute Engine APIKubernetes Engine APICloud DNS APICloud Storage API
The APIs can be enabled one by one by searching for them via the search bar at the top, clicking the search result and clicking Enable. For example, the Cloud Resource Manager API can be enabled as follows:
First, search for the API, then click on the result:
Then click on
Enable:
Depending on your organization's settings, some APIs may be enabled by default, and you don't need to enable them separately. If that's the case, you will see this instead of the
Enablebutton:
Step 2 - Add the integration in the Intruder Portal
With the service account credentials created, do the following:
Log in to
portal.intruder.ioNavigate to the
Discovery tabClick
Add asset source, then selectGoogle CloudClick on
Choose fileand select the service account key file
Click Add asset
Done! Your integration will now get imported, and will be ready for asset sync and cloud security scans.
