This article provides procedures for deploying and configuring the Microsoft Sentinel for SAP data connector agent container with expert, custom, or manual configuration options. For typical deployments we recommend that you use the portal instead.

Content in this article is intended for your SAP BASIS teams. For more information, see Deploy a SAP data connector agent from the command line.

Prerequisites

Make sure that your system complies with the prerequisites documented in the main SAP data connector prerequisites document before you start.

Manually add SAP data connector agent Azure Key Vault secrets

Use the following script to manually add SAP system secrets to your key vault. Make sure to replace the placeholders with your own system ID and the credentials you want to add:

#Add Abap username
az keyvault secret set \
  --name <SID>-ABAPUSER \
  --value "<abapuser>" \
  --description SECRET_ABAP_USER --vault-name $kvname

#Add Abap Username password
az keyvault secret set \
  --name <SID>-ABAPPASS \
  --value "<abapuserpass>" \
  --description SECRET_ABAP_PASSWORD --vault-name $kvname

#Add Java Username
az keyvault secret set \
  --name <SID>-JAVAOSUSER \
  --value "<javauser>" \
  --description SECRET_JAVAOS_USER --vault-name $kvname

#Add Java Username password
az keyvault secret set \
  --name <SID>-JAVAOSPASS \
  --value "<javauserpass>" \
  --description SECRET_JAVAOS_PASSWORD --vault-name $kvname

#Add abapos username
az keyvault secret set \
  --name <SID>-ABAPOSUSER \
  --value "<abaposuser>" \
  --description SECRET_ABAPOS_USER --vault-name $kvname

#Add abapos username password
az keyvault secret set \
  --name <SID>-ABAPOSPASS \
  --value "<abaposuserpass>" \
  --description SECRET_ABAPOS_PASSWORD --vault-name $kvname

#Add Azure Log ws ID
az keyvault secret set \
  --name <SID>-LOGWSID \
  --value "<logwsod>" \
  --description SECRET_AZURE_LOG_WS_ID --vault-name $kvname

#Add Azure Log ws public key
az keyvault secret set \
  --name <SID>-LOGWSPUBLICKEY \
  --value "<loswspubkey>" \
  --description SECRET_AZURE_LOG_WS_PUBLIC_KEY --vault-name $kvname

For more information, see the Quickstart: Create a key vault using the Azure CLI and the az keyvault secret CLI documentation.

Perform an expert / custom installation

This procedure describes how to deploy the Microsoft Sentinel for SAP data connector via the CLI using an expert or custom installation, such as when installing on-premises.

Prerequisites: Azure Key Vault is the recommended method to store your authentication credentials and configuration data. We recommend that you perform this procedure only after you have a key vault ready with your SAP credentials.

To deploy the Microsoft Sentinel for SAP data connector:

Download the latest SAP NW RFC SDK from the SAP Launchpad site > SAP NW RFC SDK > SAP NW RFC SDK 7.50 > nwrfc750X_X-xxxxxxx.zip, and save it to your data connector agent machine.

Note

You'll need your SAP user sign-in information in order to access the SDK, and you must download the SDK that matches your operating system.

Make sure to select the LINUX ON X86_64 option.
On your same machine, create a new folder with a meaningful name, and copy the SDK zip file into your new folder.

Clone the Microsoft Sentinel solution GitHub repository onto your on-premises machine, and copy Microsoft Sentinel solution for SAP applications solution systemconfig.json file into your new folder.

For example:

mkdir /home/$(pwd)/sapcon/<sap-sid>/
cd /home/$(pwd)/sapcon/<sap-sid>/
wget  https://raw.githubusercontent.com/Azure/Azure-Sentinel/master/Solutions/SAP/template/systemconfig.json 
cp <**nwrfc750X_X-xxxxxxx.zip**> /home/$(pwd)/sapcon/<sap-sid>/

Edit the systemconfig.json file as needed, using the embedded comments as a guide.

Define the following configurations using the instructions in the systemconfig.json file:
- The logs that you want to ingest into Microsoft Sentinel using the instructions in the systemconfig.json file.
- Whether to include user email addresses in audit logs
- Whether to retry failed API calls
- Whether to include cexal audit logs
- Whether to wait an interval of time between data extractions, especially for large extractions
For more information, see Manually configure the Microsoft Sentinel for SAP data connector and Define the SAP logs that are sent to Microsoft Sentinel.

To test your configuration, you might want to add the user and password directly to the systemconfig.json configuration file. While we recommend that you use Azure Key vault to store your credentials, you can also use an env.list file, Docker secrets, or you can add your credentials directly to the systemconfig.json file.

For more information, see SAL logs connector configurations.
Save your updated systemconfig.json file in the sapcon directory on your machine.

If you have chosen to use an env.list file for your credentials, create a temporary env.list file with the required credentials. Once your Docker container is running correctly, make sure to delete this file.

Note

The following script has each Docker container connecting to a specific ABAP system. Modify your script as needed for your environment.

Run:

##############################################################
# Include the following section if you're using user authentication
##############################################################
# env.list template for Credentials
SAPADMUSER=<SET_SAPCONTROL_USER>
SAPADMPASSWORD=<SET_SAPCONTROL_PASS>
LOGWSID=<SET MICROSOFT SENTINEL WORKSPACE ID>
LOGWSPUBLICKEY=<SET MICROSOFT SENTINEL WORKSPACE KEY>
ABAPUSER=SET_ABAP_USER>
ABAPPASS=<SET_ABAP_PASS>
JAVAUSER=<SET_JAVA_OS_USER>
JAVAPASS=<SET_JAVA_OS_USER>
##############################################################
# Include the following section if you are using Azure Keyvault
##############################################################
# env.list template for AZ Cli when MI is not enabled
AZURE_TENANT_ID=<your tenant id>
AZURE_CLIENT_ID=<your client/app id>
AZURE_CLIENT_SECRET=<your password/secret for the service principal>
##############################################################

Download and run the predefined Docker image with the SAP data connector installed. Run:

docker pull mcr.microsoft.com/azure-sentinel/solutions/sapcon:latest-preview
docker run --env-file=<env.list_location> -d --restart unless-stopped -v /home/$(pwd)/sapcon/<sap-sid>/:/sapcon-app/sapcon/config/system --name sapcon-<sid> sapcon
rm -f <env.list_location>

Verify that the Docker container is running correctly. Run:
```
docker logs –f sapcon-[SID]
```
Continue with deploying Microsoft Sentinel solution for SAP applications.

Deploying the solution enables the SAP data connector to display in Microsoft Sentinel and deploys the SAP workbook and analytics rules. When you're done, manually add and customize your SAP watchlists.

For more information, see Deploy the Microsoft Sentinel solution for SAP applications from the content hub.

Manually configure the Microsoft Sentinel for SAP data connector

When deployed via the CLI, the Microsoft Sentinel for SAP data connector is configured in the systemconfig.json file, which you cloned to your SAP data connector machine as part of the deployment procedure. Use the content in this section to manually configure data connector settings.

For more information, see Systemconfig.json file reference, or Systemconfig.ini file reference for legacy systems.

Define the SAP logs that are sent to Microsoft Sentinel

The default systemconfig.json file is configured to cover built-in analytics, the SAP user authorization master data tables, with users and privilege information, and the ability to track changes and activities on the SAP landscape.

The default configuration provides more logging information to allow for post-breach investigations and extended hunting abilities. However you might want to customize your configuration over time, especially as business processes tend to be seasonal.

Use the following sets of code to configure the systemconfig.json file to define the logs that are sent to Microsoft Sentinel.

For more information, see Microsoft Sentinel solution for SAP applications solution logs reference (public preview).

Configure a default profile

The following code configures a default configuration:

"logs_activation_status": {
      "abapauditlog": "True",
      "abapjoblog": "True",
      "abapspoollog": "True",
      "abapspooloutputlog": "True",
      "abapchangedocslog": "True",
      "abapapplog": "True",
      "abapworkflowlog": "True",
      "abapcrlog": "True",
      "abaptabledatalog": "False",
      "abapfileslogs": "False",
      "syslog": "False",
      "icm": "False",
      "wp": "False",
      "gw": "False",
      "javafileslogs": "False"

Configure a detection-focused profile

Use the following code to configure a detection-focused profile, which includes the core security logs of the SAP landscape required for the most of the analytics rules to perform well. Post-breach investigations and hunting capabilities are limited.

"logs_activation_status": {
      "abapauditlog": "True",
      "abapjoblog": "False",
      "abapspoollog": "False",
      "abapspooloutputlog": "False",

      "javafileslogs": "False"
    },
....
  "abap_table_selector": {
      "agr_tcodes_full": "True",
      "usr01_full": "True",
      "usr02_full": "True",
      "usr02_incremental": "True",
      "agr_1251_full": "True",
      "agr_users_full": "True",
      "agr_users_incremental": "True",
      "agr_prof_full": "True",
      "ust04_full": "True",

      "agr_flags_incremental": "True",
      "sncsysacl_full": "False",
      "usracl_full": "False",

Use the following code to configure a minimal profile, which includes the SAP Security Audit Log, which is the most important source of data that the Microsoft Sentinel solution for SAP applications uses to analyze activities on the SAP landscape. Enabling this log is the minimal requirement to provide any security coverage.

"logs_activation_status": {
      "abapauditlog": "True",
      "abapjoblog": "False",
      "abapspoollog": "False",
      "abapspooloutputlog": "False",
      "abapchangedocslog": "True",
      "abapapplog": "False",
      "abapworkflowlog": "False",
      "abapcrlog": "True",
      "abaptabledatalog": "False",
      "abapfileslogs": "False",
      "syslog": "False",
      "icm": "False",
      "wp": "False",
      "gw": "False",
      "javafileslogs": "False"
    },
....
  "abap_table_selector": {
      "agr_tcodes_full": "False",

SAL logs connector settings

Add the following code to the Microsoft Sentinel for SAP data connector systemconfig.json file to define other settings for SAP logs ingested into Microsoft Sentinel.

For more information, see Perform an expert / custom SAP data connector installation.

    "connector_configuration": {
      "extractuseremail": "True",
      "apiretry": "True",
      "auditlogforcexal": "False",
      "auditlogforcelegacyfiles": "False",
      "timechunk": "60"

This section enables you to configure the following parameters:

Parameter name	Description
extractuseremail	Determines whether user email addresses are included in audit logs.
apiretry	Determines whether API calls are retried as a failover mechanism.
auditlogforcexal	Determines whether the system forces the use of audit logs for non-SAL systems, such as SAP BASIS version 7.4.
auditlogforcelegacyfiles	Determines whether the system forces the use of audit logs with legacy system capabilities, such as from SAP BASIS version 7.4 with lower patch levels.
timechunk	Determines that the system waits a specific number of minutes as an interval between data extractions. Use this parameter if you have a large amount of data expected. For example, during the initial data load during your first 24 hours, you might want to have the data extraction running only every 30 minutes to give each data extraction enough time. In such cases, set this value to 30.

Configuring an ABAP SAP Control instance

To ingest all ABAP logs into Microsoft Sentinel, including both NW RFC and SAP Control Web Service-based logs, configure the following ABAP SAP Control details:

Setting	Description
javaappserver	Enter your SAP Control ABAP server host. For example: `contoso-erp.appserver.com`
javainstance	Enter your SAP Control ABAP instance number. For example: `00`
abaptz	Enter the time zone configured on your SAP Control ABAP server, in GMT format. For example: `GMT+3`
abapseverity	Enter the lowest, inclusive, severity level for which you want to ingest ABAP logs into Microsoft Sentinel. Values include: - 0 = All logs - 1 = Warning - 2 = Error

Configuring a Java SAP Control instance

To ingest SAP Control Web Service logs into Microsoft Sentinel, configure the following JAVA SAP Control instance details:

Parameter	Description
javaappserver	Enter your SAP Control Java server host. For example: `contoso-java.server.com`
javainstance	Enter your SAP Control ABAP instance number. For example: `10`
javatz	Enter the time zone configured on your SAP Control Java server, in GMT format. For example: `GMT+3`
javaseverity	Enter the lowest, inclusive, severity level for which you want to ingest Web Service logs into Microsoft Sentinel. Values include: - 0 = All logs - 1 = Warning - 2 = Error

Configuring User Master data collection

To ingest tables directly from your SAP system with details about your users and role authorizations, configure your systemconfig.json file with a True/False statement for each table.

For example:

    "abap_table_selector": {
      "agr_tcodes_full": "True",
      "usr01_full": "True",
      "usr02_full": "True",
