Collect Microsoft Windows DNS data

Supported in:

Google SecOps SIEM

This document:

• Describes the deployment architecture and installation steps, plus any required configuration that produce logs supported by the Google Security Operations Parser for Microsoft Windows DNS events. For an overview of Google Security Operations data ingestion, see Data ingestion to Google Security Operations.
• Includes information about how the parser maps fields in the original log to Google Security Operations Unified Data Model fields.

Based on your deployment architecture, configure BindPlane Agent or the NXLog agent to ingest Windows DNS logs into Google Security Operations. We recommend that you use BindPlane Agent to forward the Windows DNS logs into Google Security Operations.

Information in this document applies to the parser with the WINDOWS_DNS ingestion label. The ingestion label identifies which parser normalizes raw log data to structured UDM format.

Before you begin

Before you configure BindPlane Agent or the NXLog agent, complete the following tasks:

• Enable DNS diagnostic logging on the Windows DNS server.
• Configure all systems with the UTC time zone.
• Review supported devices and versions
• Review supported log types

Review supported devices and versions

The Google Security Operations parser supports logs from the following Microsoft Windows Server versions. Microsoft Windows Server is released with the following editions: Foundation, Essentials, Standard, and Datacenter. The event schema of logs generated by each edition do not differ.

• Microsoft Windows Server 2019
• Microsoft Windows Server 2016

• Microsoft Windows Server 2012 R2

  Google Security Operations parser supports logs collected by NXLog Enterprise Edition.

Review supported log types

The Google Security Operations parser supports the following log types that are generated by Microsoft Windows DNS servers. For more information about these log types, see the DNS Logging and Diagnostic documentation. The parser supports logs generated with English language text and is not supported with logs generated in non-English languages.

• Audit logs: For a description of this log type, see Audit events.
• Analytics logs: For a description of this log type, see Analytics events.
• Set up the Microsoft Windows DNS servers. For more information, see Installing and enabling DNS diagnostic logging.

Configure the BindPlane Agent

We recommend that you use BindPlane Agent to forward the Windows DNS logs into Google SecOps.

1. Install the BindPlane Agent on each Windows DNS server. For more information about installing the BindPlane Agent, see the BindPlane Agent installation instructions.

2. Create a configuration file for the BindPlane agent with the following contents.

   receivers:
     windowseventlog/dns_log:
     channel: Microsoft-Windows-DNSServer/Audit
     raw: true
   processors:
     batch:
   
   exporters:
     chronicle/dns_log:
       endpoint: https://malachiteingestion-pa.googleapis.com
       creds: '{
       "type": "service_account",
       "project_id": "malachite-projectname",
       "private_key_id": `PRIVATE_KEY_ID`,
       "private_key": `PRIVATE_KEY`,
       "client_email":"`SERVICE_ACCOUNT_NAME`@malachite-`PROJECT_ID`.`SERVICE_ACCOUNT_DOMAIN`",
       "client_id": `CLIENT_ID`,
       "auth_uri": "https://accounts.google.com/o/oauth2/auth",
       "token_uri": "https://oauth2.googleapis.com/token",

       "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/`SERVICSERVICE_ACCOUNT_NAME`%40malachite-`PROJECT_ID`.`SERVICE_ACCOUNT_DOMAIN`",
       "universe_domain": "googleapis.com"
       }'
     log_type: 'WINDOWS_DNS'
     override_log_type: false
     raw_log_field: body
     customer_id: `CUSTOMER_ID`
   
   service:
     pipelines:
       logs/dns:
         receivers:
           - windowseventlog/dns_log
         processors: [batch]
         exporters: [chronicle/dns_log]
   

3. Replace the PRIVATE_KEY_ID, PRIVATE_KEY SERVICSERVICE_ACCOUNT_NAME,PROJECT_ID, CLIENT_ID, SERVICE_ACCOUNT_DOMAIN and CUSTOMER_ID with the respective values from the service account JSON file which you can download from Google Cloud Platform. For more information about service account keys, see Create and delete service account keys documentation.

4. To start the observerIQ agent service, select Services > Extended > the observerIQ Service > start.

Configure NXLog and the Google Security Operations forwarder

The following diagram shows an architecture in which NXLog agents are installed to collect and send Microsoft Windows DNS events to Google SecOps. Compare this information with your environment to be sure these components are installed. Your deployment might be different from this representation.

If you use the NXLog agent instead of BindPlane Agent, complete the following prerequisites: - Install NXLog on clustered Microsoft Windows servers to collect and forward logs to the central Microsoft Windows or Linux server. - Install Google SecOps forwarder on the central Microsoft Windows or Linux Server.

1. Install NXLog on each Microsoft Windows DNS server. Follow the NXLog documentation.

2. Create a configuration file for each NXLog instance. Use the im_etw input module for extracting DNS analytical logs and im_msvistalog input module for audit logs.

   • For more information about the im_etw input module, see Event Tracing for Microsoft Windows (im_etw), including information about configuring NXLog for Microsoft Windows DNS.
   • For more information about the im_msvistalog input module, see Event log for Microsoft Windows 2008/Vista and later (im_msvistalog).

   Here is an example NXLog configuration. Replace <hostname> and <port> values with information about the central Microsoft Windows or Linux server. To optionally convert and parse logs to JSON, rather than XML, change the line Exec to_xml(); to Exec to_json();. For more information, see the NXLog documentation about the om_tcp module.

   define ROOT C:\Program Files\nxlog
   define WINDNS_OUTPUT_DESTINATION_ADDRESS <hostname>
   define WINDNS_OUTPUT_DESTINATION_PORT <port>

       Exec        $EventTime = integer($EventTime) / 1000;
       Exec        $EventReceivedTime = integer($EventReceivedTime) / 1000;
       Exec        to_xml(); # To collect JSON, use to_json()
   </Output>

   </Route>
   
   <Route audit_windns_to_chronicle>
       Path    auditeventlog => out_chronicle_windns
   </Route>
   

3. Install the Google Security Operations forwarder on the central Microsoft Windows or Linux server. See the Installing and configuring the forwarder on Linux or Installing and configuring the forwarder on Microsoft Windows for information about installing and configuring the forwarder.

4. Configure the Google Security Operations forwarder to send logs to Google Security Operations. Here is an example forwarder configuration.

     - syslog:
         common:
           enabled: true
           data_type: WINDOWS_DNS
           batch_n_seconds: 10

SourceModuleType im_file logs

Deprecated:

The following labels fields for UDM nouns are deprecated: about.labels, intermediary.labels, observer.labels, principal.labels, src.labels, security_result.about.labels, and target.labels. For existing parsers, in addition to these UDM fields, the logs fields are also mapped to key/value additional.fields UDM fields. For new parsers, the key/value settings in additional.fields UDM fields are used instead of the deprecated labels UDM fields. We recommend that you update the existing rules to use the key/value settings in the additional.fields UDM fields instead of the deprecated labels UDM fields.

Legacy debug logs

Deprecated:

The following labels fields for UDM nouns are deprecated: about.labels, intermediary.labels, observer.labels, principal.labels, src.labels, security_result.about.labels, and target.labels. For existing parsers, in addition to these UDM fields, the logs fields are also mapped to key/value additional.fields UDM fields. For new parsers, the key/value settings in additional.fields UDM fields are used instead of the deprecated labels UDM fields. We recommend that you update the existing rules to use the key/value settings in the additional.fields UDM fields instead of the deprecated labels UDM fields.

Field mapping reference: Event ID to UDM event type

This section describes how the parser maps Event Ids to UDM event_types. In general, events are mapped to the NETWORK_DNS metadata.event_type, except for Event IDs in the following section.

Note: The % values (e.g. %1, %2, %3, %{EventID}) are variable placeholders.
