Subscribe to events from Check Point CloudGuard

Standard

Check Point CloudGuard supports sending events to Eventarc for delivery to interested subscribers.

The Check Point CloudGuard platform provides you cloud-born security, with advanced threat prevention for all your assets and workloads – in your public, private, hybrid or multicloud environment – providing you unified security to automate security everywhere. Learn more about using Check Point CloudGuard.

To subscribe to events from Check Point CloudGuard, complete the following steps:

Before you begin

Ensure that you have enabled the Eventarc and Eventarc Publishing APIs:
Console
Enable the APIs
gcloud
```
gcloud services enable \
    eventarc.googleapis.com \
    eventarcpublishing.googleapis.com
```
If you are enabling a customer-managed encryption key (CMEK) for a channel, enable the Cloud Key Management Service API.
Console
Enable the API
gcloud
```
gcloud services enable cloudkms.googleapis.com
```

Retrieve the provider name used by Check Point CloudGuard

The provider name is required when creating and using a channel. You can list all Eventarc providers and retrieve their details, including supported event types, by running gcloud commands.

For example, you can list all third-party providers in any location:

gcloud eventarc providers list --filter='eventTypes.type!~^google*' --location=-

The output includes something similar to the following:

NAME: cloudguard
LOCATION: us-central1

For details, see List event providers.

Retrieve the events supported by Check Point CloudGuard

An event type is needed when creating an Eventarc trigger. You can list Check Point CloudGuard's supported event types, by running a gcloud command:

gcloud eventarc providers describe cloudguard \
    --location=LOCATION

Replace LOCATION with a supported Eventarc region.

For example:

gcloud eventarc providers describe cloudguard --location=us-central1

The output is similar to the following:

displayName: Check Point CloudGuard
eventTypes:
- type: cloudguard.v1.event
name: projects/project-id/locations/us-central1/providers/cloudguard
[...]

Make note of the event type to use when creating an Eventarc trigger.

Create a channel for Check Point CloudGuard events

To subscribe to events from Check Point CloudGuard, you must create a channel:

Console

In the Google Cloud console, go to the Eventarc > Channels page.

Go to Channels
Click Create channel.
Select a Channel type and Provider.

For example, select Third-party > Check Point CloudGuard.
In the Channel name field, enter a name for the channel.
In the Region list, select a supported Eventarc region.
Optionally, select the Use a customer-managed encryption key (CMEK) checkbox and, in the CMEK encryption key list, select a key ring that you have created for the region.

For more information, see Use customer-managed encryption keys.
Click Create.

gcloud

gcloud eventarc channels create CHANNEL_NAME \
    --provider cloudguard \
    --project PROJECT_ID \
    --location LOCATION

Replace the following:

CHANNEL_NAME: a name for the channel
PROJECT_ID: your Google Cloud project ID

You can find your project ID on the Welcome page of the Google Cloud console.
LOCATION: a supported Eventarc region

Note: For this Pre-GA feature, only us-central1 is supported as a location. You cannot create a channel in any other location.

You can optionally use a --crypto-key flag to specify a fully qualified Cloud KMS key name in the format projects/PROJECT_NAME/locations/LOCATION/keyRings/RING_NAME/cryptoKeys/KEY_NAME.

For more information, see Use customer-managed encryption keys.

For details, see Create a channel.

Retrieve specific details to convey to Check Point CloudGuard

After creating a channel, you can retrieve specific details to convey to Check Point CloudGuard:

Console

In the Google Cloud console, go to the Eventarc > Channels page.

Go to Channels
From the list of channels, click a channel to view its details.

The channel status should be Pending.
Copy the Channel full name and Activation token value. Both will be needed later to convey to Check Point CloudGuard and activate the channel.

gcloud

gcloud eventarc channels describe CHANNEL_NAME \
    --project PROJECT_ID \
    --location LOCATION

The output is similar to the following:

activationToken: aS7dXs1b79AcXsf
createTime: '2021-11-15T15:20:31.582356065Z'
name: projects/project-id/locations/us-central1/channels/cloudguard-channel
provider: projects/project-id/locations/us-central1/providers/cloudguard
pubsubTopic: projects/project-id/topics/eventarc-channel-us-central1-cloudguard-channel-077
state: PENDING
uid: c6703a91-ccd3-4c32-a729-967393f23a29
updateTime: '2021-11-15T15:21:03.689597653Z'

Note that the channel is in a PENDING state. To activate the channel, you must provide the activationToken value and the channel name to Check Point CloudGuard.

Learn more about the channel state.

Create an API key in Check Point CloudGuard

Before activating the channel, you must create an API key in Check Point CloudGuard.

Log into the Check Point CloudGuard console.
Select Settings > Credentials.
Click Create API Key.

The New API key created dialog opens.
Before closing the dialog, save the ID and Secret data. Once the dialog is closed, the data is not accessible.
```

PASSWORD=API_KEY_SECRET
```
Replace the following:
- API_KEY_ID: the ID of the API key.
- API_KEY_SECRET: the secret of the API key.
For more information, see Credentials.
Click OK.

Deploy an event receiver

To test the configuration, deploy an event receiver—in this case, a Workflows workflow that logs received events—and create an Eventarc trigger that routes events from Check Point CloudGuard to the event receiver. You must use a service account that has been granted the appropriate roles to access your Google Cloud project resources.

Enable the Workflows and Workflow Executions APIs:

Console

Enable the APIs

gcloud

gcloud services enable \
    workflows.googleapis.com \
    workflowexecutions.googleapis.com

Create a service account and grant it the roles/logging.logWriter and roles/workflows.invoker roles:
Console
1. In the Google Cloud console, go to the Service Accounts page.
  
  Go to Service Accounts
2. Select your project.
3. In the Service account name field, enter a name. The Google Cloud console fills in the Service account ID field based on this name. Optionally, add a description.
4. Click Create and continue.
5. In the Select a role list, select Logging > Logs Writer.
6. Click Add another role and select Workflows > Workflows Invoker.
7. Click Continue.
8. To finish creating the service account, click Done.
gcloud
```
gcloud iam service-accounts create MY_SERVICE_ACCOUNT
gcloud projects add-iam-policy-binding PROJECT_ID \
    --role="roles/workflows.invoker" \
    --member="serviceAccount:MY_SERVICE_ACCOUNT@PROJECT_ID.iam.gserviceaccount.com"
gcloud projects add-iam-policy-binding PROJECT_ID \
    --role="roles/logging.logWriter" \
    --member="serviceAccount:MY_SERVICE_ACCOUNT@PROJECT_ID.iam.gserviceaccount.com"
```
Replace MY_SERVICE_ACCOUNT with a name for your service account.
For more information about how to control access to Workflows resources, see Use IAM to control access.
Create and deploy a workflow that logs a received event:
Console
1. In the Google Cloud console, go to the Workflows page.
  
  Go to Workflows
2. Click Create.
3. Name your workflow logEventsWorkflow.
4. Choose a supported Workflows region; for example, us-central1.
5. Select the Service account you previously created.
6. Click Next.
7. In the workflow editor, enter the following definition for your workflow:
```
main:
  params: [event]
  steps:
  - logStep:
      call: sys.log
      args:
        data: ${event}
```
8. Click Deploy.
gcloud
1. Open a terminal or Cloud Shell.
2. In your home directory, create a new file called logEventsWorkflow.yaml.
3. Copy and paste the following into the new file and save it:
```
main:
  params: [event]
  steps:
  - logStep:
      call: sys.log
      args:
        data: ${event}
```
4. Deploy the workflow:
```
gcloud workflows deploy logEventsWorkflow \
    --source=logEventsWorkflow.yaml \
    --location LOCATION
```
  Replace LOCATION with a supported Workflows region; for example, us-central1.
Create an Eventarc trigger to route events from Check Point CloudGuard to the target workflow:
Console
1. In the Google Cloud console, go to the Eventarc > Triggers page.
  
  Go to Triggers
2. Click Create trigger.
3. Type a Trigger name.
  
  This is the ID of the trigger and it must start with a letter. For example, my-event-channel-trigger.
4. Select a Trigger type and Event provider.
  
  This is the partner service that is the source of events. For example, select Third-party > Check Point CloudGuard.
5. Select the appropriate Channel.
6. Select an Event.
  
  For example: cloudguard.v1.event
7. Optionally, in the Filters section, specify an appropriate attribute and value.
8. Select the Service account you previously created to invoke your workflow.
9. For the Event destination, select Workflows, and then select the workflow you previously created.
10. Click Create.
gcloud
```
gcloud eventarc triggers create TRIGGER \
    --location=LOCATION \
    --destination-workflow=logEventsWorkflow  \
    --event-filters=type=cloudguard.v1.event \
    --channel=CHANNEL_NAME \
    --project=PROJECT_ID \
    --service-account="MY_SERVICE_ACCOUNT@PROJECT_ID.iam.gserviceaccount.com"
```
Replace TRIGGER with the ID of the trigger or a fully qualified identifier. For example, my-event-channel-trigger.
For more information, see Create a trigger for a third-party provider.

Configure the integration to support event routing

Configure the integration to support the routing of events from Check Point CloudGuard. You can do this through Check Point CloudGuard's API using an API request tool or by making curl calls.

Convey the Eventarc channel full name and activation token to Check Point CloudGuard. For example:

CHANNEL_NAME=CHANNEL_FULL_NAME
TOKEN=ACTIVATION_TOKEN

curl -v --request POST \
    --url https://api.dome9.com/v2/Compliance/ContinuousComplianceNotification/eventarcChannelConnection \
    -u $USERNAME:$PASSWORD \
    --header 'accept: application/json' \
    --header 'content-type: application/json' \
    --data @- << EOF
    {
      "activationToken": "$TOKEN",
      "channelFullName": "$CHANNEL_NAME"
    }
EOF

Replace the following:

CHANNEL_FULL_NAME: the channel name, including the Google Cloud project ID and location of the resource. For example:
```
projects/PROJECT_ID/locations/LOCATION/channels/CHANNEL_NAME
```
ACTIVATION_TOKEN: the token is valid for 24 hours after the channel's creation. After 24 hours, the channel becomes INACTIVE.

If the curl command is successful, the output is similar to the following, and a channel connection ID is returned:

HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
Content-Length: 38
...
Connection #0 to host api.dome9.com left intact
"af094362-37da-4a42-ac73-882738406a45"

Save the channel connection ID (for example, af094362-37da-4a42-ac73-882738406a45) to use when setting up a notification handler:
```
CHANNEL_CONNECTION_ID=CHANNEL_CONNECTION_ID
```

If you run the gcloud eventarc channels describe CHANNEL_NAME command again, the channel state should now be ACTIVE. For example:

createTime: '2022-07-13T11:05:09.714896959Z'
name: projects/eventarc-test-project/locations/us-central1/channels/test-cloudguard
provider: projects/eventarc-test-project/locations/us-central1/providers/cloudguard
pubsubTopic: projects/eventarc-test-project/topics/eventarc-channel-us-central1-test-cloudguard-430
state: ACTIVE

Set up a notification handler to watch for specific access events in Check Point CloudGuard and forward notification of these events to Eventarc. For example:

NOTIFICATION_NAME=NOTIFICATION_NAME

curl -v --request POST \
    --url https://api.dome9.com/v2/Compliance/ContinuousComplianceNotification \
    --header 'accept: application/json' \
    --header 'content-type: application/json' \
    -u $USERNAME:$PASSWORD \
    --data @- << EOF
    {
    "changeDetection": {
        "eventarcData": {
            "channelConnectionId": "$CHANNEL_CONNECTION_ID"
        },
        "eventarcIntegrationState": "Enabled"
    },
    "name": "$NOTIFICATION_NAME"
    }
EOF

Replace NOTIFICATION_NAME with a unique name to identify the notification.

The output from the curl command is similar to the following:

HTTP/1.1 201 Created
Date: Thu, 13 Jul 2022 11:48:36 GMT
Content-Type: application/json; charset=utf-8
Content-Length: 887

Log into the Check Point CloudGuard console.
Select Posture management > Continuous posture.
Select the checkbox for the GCP CloudGuard Best Practices ruleset and click Edit.
Select the notification you previously configured and then click Save.

Test the routing of events

You can now test the entire configuration by accessing Check Point CloudGuard to trigger an event, and ensuring that the event from Check Point CloudGuard is routed to the workflow event receiver which logs the received event.

Create a Google Cloud resource to simulate a violation of the Check Point CloudGuard ruleset; for example, create a public Cloud Storage bucket.
Log into the Check Point CloudGuard console.
Select Posture management > Continuous posture.
Select the GCP CloudGuard Best Practices ruleset and click Run Assessment.

The assessment detects that the Cloud Storage bucket is public and generates an event for Eventarc. Note that the event generation might take some time.

To verify that a workflow execution was triggered by the received event, list the last five executions:

gcloud workflows executions list ${MY_WORKFLOW} --limit=5

The output is similar to the following, listing a NAME and STATE equal to SUCCEEDED for each workflow execution.

NAME: projects/1051295516635/locations/us-central1/workflows/logEventsWorkflow/executions/674b5783-deec-4d1b-be1d-b067f7b32971
STATE: SUCCEEDED
START_TIME: 2022-07-13T22:01:06.314980819Z
END_TIME: 2022-07-13T22:01:06.637825944Z

Every time a workflow executes a single run of the logic contained in a workflow's definition, it automatically triggers at least two execution logs: one at the start of an execution and one at the end. To view the logs do the following:
1. In the Google Cloud console, go to the Workflows page:
  
  Go to Workflows
2. To access a workflow's Details page, click the workflow's name.
3. To view the execution details, in the Executions tab, click a specific Execution ID.
