Raccogliere i log di Microsoft Windows AD

Questo documento include le seguenti informazioni:

• Architettura di deployment e passaggi di installazione, oltre a qualsiasi configurazione richiesta che produca log supportati dal parser di Google Security Operations per gli eventi di Microsoft Windows Active Directory. Per una panoramica sull'importazione dati in Google Security Operations, consulta Importazione dei dati in Google Security Operations.
• Informazioni su come il parser mappa i campi nel log originale ai campi del modello UDM (Unified Data Model) di Google Security Operations.

In base all'architettura di deployment, configura l'agente Bindplane o l'agente NXLog per importare i log di Microsoft Windows Active Directory in Google Security Operations. Ti consigliamo di utilizzare Bindplane Agent per inoltrare i log di Windows Active Directory a Google Security Operations.

Le informazioni contenute in questo documento si applicano al parser con l'etichetta di importazione WINDOWS_AD. L'etichetta di importazione identifica quale parser normalizza i dati di log non elaborati nel formato UDM strutturato.

Prima di iniziare

Prima di configurare l'agente Bindplane o l'agente NXLog, completa le seguenti attività:

• Configura tutti i sistemi in modo che utilizzino il fuso orario UTC.
• Configura i server Microsoft Windows AD.
• Esamina i dispositivi e le versioni supportati.
• Controlla i tipi di log supportati.

Configurare i server Microsoft Windows AD

1. Su ogni server Microsoft Windows Active Directory, crea e configura uno script PowerShell per salvare i dati di log in un file di output. Bindplane Agent o NXLog Agent legge il file di output.

   # Set the location where the log file will be written
   $OUTPUT_FILENAME="<Path_of_the_output_file>"
   
   If (Test-Path -Path $OUTPUT_FILENAME) { Remove-Item -path $OUTPUT_FILENAME -ErrorAction SilentlyContinue}
   
   # USER_CONTEXT: Gets all Active Directory users and their properties.
   Get-ADUser -Filter * -properties samAccountName | % { Get-ADUser $_.SamAccountName -properties * | ConvertTo-JSON -compress | Out-File -encoding utf8 $OUTPUT_FILENAME -Append }
   
   # ASSET_CONTEXT: Gets all Active Directory assets and their properties.
   Get-ADComputer -Filter * -properties samAccountName | % { Get-ADComputer $_.SamAccountName -properties * | ConvertTo-JSON -compress | Out-File -encoding utf8 $OUTPUT_FILENAME -Append }
   

2. Sostituisci quanto segue :

   • Sostituisci il valore di $OUTPUT_FILENAME con la posizione del file di output.
   • Memorizza i dati in formato JSON.
   • Imposta la codifica su UTF-8.
   • Utilizza il parametro -Filter anziché il parametro -LDAPFilter quando chiami i cmdlet Get-ADUser e Get-ADComputer.

3. Crea un'attività ricorrente che esegue lo script per recuperare e scrivere i dati nel file di output.

   1. Apri l'applicazione Utilità di pianificazione.
   2. Fai clic su Crea attività.
   3. Inserisci un nome e una descrizione per l'attività.
   4. Seleziona la casella di controllo Esegui con i privilegi più elevati per assicurarti che vengano recuperati tutti i dati.
   5. Nella scheda Trigger, definisci quando vuoi ripetere l'attività.
   6. Nella scheda Azione, aggiungi una nuova azione e fornisci il percorso del file in cui è memorizzato lo script.

Rivedere i dispositivi e le versioni supportati

Microsoft Windows Server viene rilasciato con le seguenti edizioni: Foundation, Essentials, Standard e Datacenter. Lo schema degli eventi dei log generati da ogni edizione non differisce.

Il parser di Google Security Operations supporta i log delle seguenti versioni di Microsoft Windows Server:

• Microsoft Windows Server 2019
• Microsoft Windows Server 2016
• Microsoft Windows Server 2012

Il parser Google Security Operations supporta i log raccolti da NXLog Community Edition o Enterprise Edition.

Rivedi i tipi di log supportati

Il parser di Google Security Operations analizzerà e normalizzerà i dati recuperati dal contesto utente e dal contesto asset. Supporta i log generati con testo in lingua inglese e non supporta i log generati in lingue diverse dall'inglese.

Configura l'agente BindPlane

Ti consigliamo di utilizzare l'agente Bindplane per inoltrare i log di Windows Active Directory a Google Security Operations.

Dopo l'installazione, il servizio dell'agente Bindplane viene visualizzato come servizio observIQ nell'elenco dei servizi Windows.

1. Installa l'agente Bindplane su ogni server Windows Active Directory. Per saperne di più sull'installazione dell'agente Bindplane, consulta le istruzioni di installazione dell'agente Bindplane.

2. Crea un file di configurazione per l'agente Bindplane con i seguenti contenuti:

   receivers:
     filelog:
       include: [ `FILE_PATH` ]
       operators:
         - type: json_parser
       start_at: beginning
     windowseventlog/activedirectoryservice:
       channel: Directory Service
       raw: true
   processors:
     batch:
   
   exporters:
     chronicle/activedirectory:
       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`.iam.gserviceaccount.com",
       "client_id": `CLIENT_ID`,
       "auth_uri": "https://accounts.google.com/o/oauth2/auth",
       "token_uri": "https://oauth2.googleapis.com/token",
       "auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs",
       "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/`SERVICSERVICE_ACCOUNT_NAME`%40malachite-`PROJECT_ID`.iam.gserviceaccount.com",
       "universe_domain": "googleapis.com"
       }'
     log_type: 'WINDOWS_AD'
     override_log_type: false
     raw_log_field: body
     customer_id: `CUSTOMER_ID`
   
   service:
     pipelines:
       logs/ads:
         receivers:
           - filelog
           - windowseventlog/activedirectoryservice
         processors: [batch]
         exporters: [chronicle/activedirectory]
   

3. Sostituisci quanto segue :

   • FILE_PATH con il percorso del file in cui è stato memorizzato l'output dello script PowerShell menzionato in Configurare i server AD Microsoft Windows.

   • PRIVATE_KEY_ID, PRIVATE_KEY SERVICSERVICE_ACCOUNT_NAME,PROJECT_ID, CLIENT_ID e CUSTOMER_ID con i rispettivi valori del file JSON dell'account di servizio, che puoi scaricare da Google Cloud. Per saperne di più sulle chiavi dei account di servizio, vedi Creare ed eliminare le account di servizio account.

4. Per avviare il servizio dell'agente Bindplane (precedentemente noto come observIQ), seleziona Servizi > Esteso > il servizio observIQ > Avvia.

Configura l'agente NXLog

Il seguente diagramma mostra un'architettura in cui sono installati gli agenti NXLog per raccogliere e inviare eventi Microsoft Windows a Google Security Operations. Confronta queste informazioni con il tuo ambiente per assicurarti che questi componenti siano installati. Il tuo deployment potrebbe essere diverso da questa architettura e potrebbe essere più complesso.

Se utilizzi l'agente NXLog anziché l'agente Bindplane, verifica quanto segue:

• Uno script PowerShell viene creato e configurato su ogni Microsoft Windows Server che esegue Active Directory per raccogliere i dati USER_CONTEXT e ASSET_CONTEXT. Per ulteriori informazioni, consulta Configurare i server AD di Microsoft Windows.
• NXLog è installato su ogni server Microsoft Windows AD per inviare dati al server Microsoft Windows Server o Linux centrale.
• Il forwarder Google Security Operations è installato sul server Microsoft Windows Server o Linux centrale per inoltrare i dati di log a Google Security Operations.

Configura NXLog

1. Installa l'agente NXLog su ogni raccoglitore in esecuzione sul server Windows Active Directory. Questa applicazione inoltra i log al server centrale Microsoft Windows o Linux. Per saperne di più, consulta la documentazione di NXLog.

2. Crea un file di configurazione per ogni istanza di NXLog. Utilizza il modulo NXLog im_file per leggere dal file e analizzare le righe in campi. Utilizza om_tcp per inoltrare i dati al server centrale Microsoft Windows o Linux.

   Di seguito è riportato un esempio della configurazione di NXLog. Sostituisci i valori <hostname> e <port> con informazioni sul server Microsoft Windows o Linux centrale di destinazione. Nella sezione <Input in_adcontext> e nella proprietà File, aggiungi il percorso del file di log di output scritto dallo script PowerShell. Imposta sempre DirCheckInterval e PollInterval. Se non sono definiti, NXLog esegue il polling dei file ogni secondo.

   define ROOT C:\Program Files\nxlog
   define ADCONTEXT_OUTPUT_DESTINATION_ADDRESS <hostname>
   define ADCONTEXT_OUTPUT_DESTINATION_PORT <port>
   
   Moduledir   %ROOT%\modules
   CacheDir    %ROOT%\data
   Pidfile     %ROOT%\data\nxlog.pid
   SpoolDir    %ROOT%\data
   LogFile     %ROOT%\data\nxlog.log
   
   <Input in_adcontext>
       Module im_file
       File "<Path_of_the_output_file>"
       DirCheckInterval 3600
       PollInterval 3600
   </Input>
   
   <Output out_chronicle_adcontext>
       Module  om_tcp
       Host    %ADCONTEXT_OUTPUT_DESTINATION_ADDRESS%
       Port    %ADCONTEXT_OUTPUT_DESTINATION_PORT%
   </Output>
   
   <Route ad_context_to_chronicle>
       Path in_adcontext => out_chronicle_adcontext
   </Route>
   

3. Avvia il servizio NXLog in ogni sistema.

Configurare l'inoltratore su un server centrale

Per informazioni sull'installazione e la configurazione del forwarder su Linux, consulta Installazione e configurazione del forwarder su Linux. Per informazioni sull'installazione e la configurazione del forwarder su Microsoft Windows, vedi Installazione e configurazione del forwarder su Microsoft Windows.

1. Configura il sistema con il fuso orario UTC.
2. Installa il forwarder Google Security Operations sul server centrale Microsoft Windows o Linux.

3. Configura il forwarder Google Security Operations per inviare i log a Google Security Operations. Di seguito è riportata una configurazione di esempio dell'agente di inoltro:

     - syslog:
         common:
           enabled: true
           data_type: WINDOWS_AD
           batch_n_seconds: 10
           batch_n_bytes: 1048576
         tcp_address: 0.0.0.0:10518
         connection_timeout_sec: 60
