Collect Microsoft LAPS logs

Supported in:

This document explains how to ingest the Microsoft LAPS (Local Administrator Password Solution) logs to Google Security Operations using Bindplane. The parser first extracts JSON formatted data from the message field and then further parses the EventData field within the extracted JSON. It then maps the extracted fields to the Unified Data Model (UDM) schema, categorizes the event type based on the EventId, and finally merges all the processed data into the output event.

Before you begin

Ensure that you have the following prerequisites:

  • Google SecOps instance
  • if running behind a proxy, firewall ports are open
  • Privileged access to a Microsoft Windows Server with LAPS

Get Google SecOps ingestion authentication file

  1. Sign in to the Google SecOps console.
  2. Go to SIEM Settings > Collection Agents.
  3. Download the Ingestion Authentication File. Save the file securely on the system where Bindplane will be installed.

Get Google SecOps customer ID

  1. Sign in to the Google SecOps console.
  2. Go to SIEM Settings > Profile.
  3. Copy and save the Customer ID from the Organization Details section.

Install the Bindplane agent

Windows installation

  1. Open the Command Prompt or PowerShell as an administrator.
  2. Run the following command:

    msiexec /i "https://github.com/observIQ/bindplane-agent/releases/latest/download/observiq-otel-collector.msi" /quiet
    

Additional installation resources

For additional installation options, consult the installation guide.

Configure the Bindplane agent to ingest Syslog and send to Google SecOps

  1. Access the configuration file:
    • Locate the config.yaml file. Typically, it's in the installation directory on Windows.
    • Open the file using a text editor (for example, Notepad).
  2. Edit the config.yaml file as follows:

    receivers:
      windowseventlog/laps_operational:
        channel: Microsoft-Windows-LAPS/Operational
        max_reads: 100
        poll_interval: 5s
        raw: true
        start_at: end
    
    processors:
      batch:
    
    exporters:
      chronicle/laps:
            # Adjust the path to the credentials file you downloaded in Step 1
            creds: '/path/to/ingestion-authentication-file.json'
            # Replace with your actual customer ID from Step 2
            customer_id: <customer_id>
            endpoint: malachiteingestion-pa.googleapis.com
            # Add optional ingestion labels for better organization
            log_type: 'WINDOWS_LAPS'
            override_log_type: false
            raw_log_field: body
    
    service:
      pipelines:
        logs/laps:
          receivers:
          - windowseventlog/laps_operational
          processors: [batch]
          exporters: [chronicle/laps]
    
  3. Replace <customer_id> with the actual Customer ID.

  4. Update /path/to/ingestion-authentication-file.json to the path where the authentication file was saved in the Get Google SecOps ingestion authentication file section.

Restart the Bindplane agent to apply the changes

  • To restart the Bindplane agent in Windows, you can either use the Services console or enter the following command:

    net stop BindPlaneAgent && net start BindPlaneAgent
    

Configure Microsoft Windows LAPS

  1. Type eventvwr.msc at an elevated command prompt and press ENTER to open Event Viewer.
  2. Go to Applications and Services Logs > Microsoft > Windows > LAPS.
  3. Expand LAPS.
  4. Right-click LAPS, and then click Properties.
  5. Select the Enable logging checkbox.
  6. Click OK when asked if the log is enabled.
  7. Click OK.
