Collect Lacework Cloud Security logs

Overview

This parser extracts fields from Lacework Cloud Security JSON logs, transforming them into UDM format. It maps raw log fields to UDM fields, handling various data types and enriching the event with additional context from tags, ultimately classifying the event type based on the presence of principal and target information.

Before you begin

• Ensure that you have a Google SecOps instance.
• Ensure that you have privileged access to FortiCNAPP Lacework.

Configure a feed in Google SecOps to ingest the Lacework logs

1. Go to SIEM Settings > Feeds.
2. Click Add new.
3. In the Feed name field, enter a name for the feed (for example, Lacework Logs).
4. Select Webhook as the Source type.
5. Select Lacework as the Log type.
6. Click Next.
7. Optional: Specify values for the following input parameters:
   • Split delimiter: the delimiter that is used to separate log lines, such as \n.
   • Asset namespace: the asset namespace.
   • Ingestion labels: the label applied to the events from this feed.
8. Click Next.
9. Review the feed configuration in the Finalize screen, and then click Submit.
10. Click Generate Secret Key to generate a secret key to authenticate this feed.
11. Copy and store the secret key. You cannot view this secret key again. If needed, you can regenerate a new secret key, but this action makes the previous secret key obsolete.
12. From the Details tab, copy the feed endpoint URL from the Endpoint Information field. You need to specify this endpoint URL in your client application.
13. Click Done.

Create an API key for the webhook feed

1. Go to Google Cloud console > Credentials.

   Go to Credentials

2. Click Create credentials, and then select API key.

3. Restrict the API key access to the Chronicle API.

Specify the endpoint URL

1. In your client application, specify the HTTPS endpoint URL provided in the webhook feed.

2. Enable authentication by specifying the API key and secret key as part of the custom header in the following format:

   X-goog-api-key = API_KEY
   X-Webhook-Access-Key = SECRET
   

   Recommendation: Specify the API key as a header instead of specifying it in the URL.

3. If your webhook client doesn't support custom headers, you can specify the API key and secret key using query parameters in the following format:

   ENDPOINT_URL?key=API_KEY&secret=SECRET
   

   Replace the following:

   • ENDPOINT_URL: the feed endpoint URL.
   • API_KEY: the API key to authenticate to Google SecOps.
   • SECRET: the secret key that you generated to authenticate the feed.

Configure a Lacework Webhook for Google SecOps

1. Sign in to the Lacework FortiCNAPP Console with administrative privileges.
2. Go to Settings > Notifications > Alert channels.
3. Click + Add new.
4. Select Webhook.
5. Click Next.
6. Specify a unique name to the channel (for example, Google SecOps).
7. Webhook URL: enter the <ENDPOINT_URL> followed by <API_KEY> and <SECRET>.
8. Click Save.
9. Select Alert rules and configure your required alert routing details.
