Collect Sysdig logs

This parser extracts security event data from Sysdig JSON logs, transforming and mapping the raw log fields into the Google Security Operations UDM format. It handles various fields, including metadata, principal or target information, security result details, and Kubernetes-related context, enriching the data for analysis within Google SecOps. The parser also performs data type conversions, error handling, and conditional logic based on field values to ensure accurate and comprehensive UDM representation.

Before you begin

Ensure that you have the following prerequisites:

• Google SecOps instance.
• Privileged access to Sysdig Secure.

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 Google Security Operations API.

Option 1

Set up feeds

To configure a feed, follow these steps:

1. Go to SIEM Settings > Feeds.
2. Click Add New Feed.
3. On the next page, click Configure a single feed.
4. In the Feed namefield, enter a name for the feed; for example, Sysdig Logs.
5. Select Webhookas the Source type.
6. Select Sysdigas the Log type.
7. Click Next.

8. Optional: Specify values for the following input parameters:

   • Split delimiter: the delimiter that is used to separate log lines, such as \n .

9. Click Next.

10. Review the feed configuration in the Finalizescreen, and then click Submit.

11. Click Generate Secret Keyto generate a secret key to authenticate this feed.

12. 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.

13. From the Detailstab, copy the feed endpoint URL from the Endpoint Informationfield. You need to specify this endpoint URL in your client application.

14. Click Done.

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 Webhook in Sysdig

1. Sign in to Sysdig Secure with Admin privileges.
2. Go to Profile > Settings > Event Forwarding.
3. Click +Add Integrationand select Webhookfrom the drop-down.

4. Specify values for the following input parameters:

   • Integration Name: Provide a descriptive name for the webhook (for example, Google SecOps Webhook).
   • Endpoint: Enter the Webhook <ENDPOINT_URL> , followed by <API_KEY and <SECRET> .

   • Data to Send: Select from the drop-down the types of Sysdig data that should be forwarded.

   • Test the integration, then toggle Enabledto activate it.

   • Click Save.

Option 2

Forward data directly to Google SecOps

1. Sign in to Sysdig Secure using your administrator credentials.
2. Go to Settings > Event Forwarding.
3. Click +Add Integrationand select Google Chroniclefrom the drop-down.
4. Specify values for the following input parameters:
   • Integration Name: Provide a descriptive name for the integration (for example, Google SecOps Integration).
   • Customer ID: The Google Customer ID associated with your Google Cloud account. (In Google SecOps, find this in Settings > Profile).
   • Namespace: Optional: Use as a tag to identify the appropriate data domain for indexing and enrichment.
   • JSON Credentials: Upload your Google SecOps JSON credentials.
   • Region: Select your region, such as US, Europe, or Asia.
   • Data to Send: Select the types of Sysdig data that should be forwarded from the drop-down.
   • Test the integration, then toggle Enabledto activate it.
   • Click Save.
