Collect CloudPassage Halo logs

Supported in:

This Logstash parser code transforms CloudPassage Halo JSON log data into a unified data model (UDM). It extracts relevant fields from the raw logs, normalizes timestamps, maps data to UDM fields, and enriches events with additional context like severity and user information.

Before you begin

Ensure that you have the following prerequisites:

  • Google SecOps instance.
  • Privileged access to CloudPassage Halo.

Configuring an API key in CloudPassage

  1. Sign in to CloudPassage Halo.
  2. Go to Settings > Site Administration.
  3. Click the API Keys tab.
  4. Click Actions > New Api Key.
  5. Click Show for your key on the API Keys tab to display values.
  6. Copy both the Key ID and the Secret Key values.

Set up feeds

There are two different entry points to set up feeds in the Google SecOps platform:

  • SIEM Settings > Feeds
  • Content Hub > Content Packs

  6. Select Cloud Passage as the Log type.
  7. Click Next.
  8. Specify values for the following input parameters:
    • Username: enter the Key ID.
    • Secret: enter the Secret Key.
    • Event Types: type of events to include (if you don't specify event types, default events from the list will be used).
  9. Click Next.
  10. Review the feed configuration in the Finalize screen, and then click Submit.

Set up feeds from the Content Hub

created_at metadata.event_timestamp Converted to UDM timestamp format from the created_at field in the raw log.
critical security_result.severity If critical is true, severity is set to "CRITICAL". Otherwise, it's set to "INFORMATIONAL" for events and calculated based on findings count for scans.
id metadata.product_log_id Directly mapped from the id field in the raw log for events.
message security_result.description Extracted description from the message field using grok pattern.

rule_name security_result.rule_name Directly mapped from the rule_name field in the raw log.
scan.created_at metadata.event_timestamp Converted to UDM timestamp format from the scan.created_at field in the raw log for scans.
scan.critical_findings_count security_result.description Used to calculate the description for scan events. Also used to determine the severity level.
scan.module security_result.summary Used to generate the summary for scan events. Converted to uppercase.
scan.non_critical_findings_count security_result.description Used to calculate the description for scan events. Also used to determine the severity level.
scan.ok_findings_count security_result.description Used to calculate the description for scan events.
scan.server_hostname target.hostname Directly mapped from the scan.server_hostname field in the raw log for scans.
scan.status security_result.summary Used to generate the summary for scan events.
scan.url metadata.url_back_to_product Directly mapped from the scan.url field in the raw log for scans.
server_group_name target.group.attribute.labels.server_group_name Directly mapped from the server_group_name field in the raw log.
