Integrate with SAP NetWeaver

The Scanner feature enables you to protect your SAP deployments using Workload Security, helping to secure critical information from attack, including a wide variety of threats such as malware, cross-site scripting and SQL injection. Workload Security scans content uploaded to the SAP NetWeaver technology platform to determine its true type and reports this to SAP systems via the NetWeaver-VSI interface. Content scanning protects against possible malicious script content that might be embedded or disguised inside documents. SAP administrators can then set policy according to which document types should be allowed.

Scanner is not supported on computers with a relay-enabled agent.

How it works

  1. SAP customer environments are secured through the SAP Virus Scan Interface (VSI), the security component of the SAP NetWeaver platform. The VSI is used to secure all forms of customer content including documents, embedded images, and active content including JavaScript and scripts in PDF and Office documents. The Scanner feature works seamlessly with SAP NetWeaver technology and the SAP HANA® platform.
  2. The Workload Security Scanner feature scans the content uploaded to the SAP NetWeaver technology platform to determine its true type and reports this to SAP systems via the NetWeaver VSI interface. Content scanning protects against possible malicious script content that might be embedded or disguised inside documents.
  3. SAP administrators can then set policy according to which actual document types should be allowed.

Workload Security and SAP components

Workload Security connects with the Deep Security Agent located on the SAP NetWeaver server. The agent connects with libsapvsa or dsvsa.dll, which are the virus adapters provided by Trend Micro for scanning purposes.

The components involved in this solution are:

  • Workload Security: The centralized web-based management console that administrators use to configure security policy and deploy protection to the Deep Security Agent.
  • Deep Security Agent: A security agent deployed directly on a computer. The nature of that protection depends on the rules and security settings that each agent receives from Workload Security.
  • SAP NetWeaver: SAP integrated technology computing platform. The SAP NetWeaver Virus Scan Interface (NW-VSI) provides virus scanning capabilities for third-party products that perform the actual scan. The NW-VSI interface must be activated.
  • SAP NetWeaver ABAP WinGUI: A Windows management console used for SAP NetWeaver. In this document, it is used for the configuration of the Deep Security Agent and the SAP NetWeaver Virus Scan Interface.

SAP architecture

Set up the integration between Workload Security Scanner and SAP NetWeaver

  1. Purchase the Scanner feature for your Workload Security account. When the order is complete, you will be able to see the feature in your Workload Security console. To check whether the feature is enabled, open the computer or policy editor and go to Settings. You should see a Scanner tab.
  2. Check the Supported features by platform page to see which operating systems support the Scanner feature.
  3. Install the Deep Security Agent on an SAP application server that's running one of the supported operating systems. See Install the agent‌.
  4. Add the SAP server to Workload Security and activate the agent on the SAP server. See Add the SAP server to Workload Security and activate the agent.
  5. Enable the SAP integration feature in a computer or policy. See Assign a security profile‌.
  6. Configure the SAP Virus Scan Interface (VSI) by calling the following transactions. See Configure SAP to use the agent:
    • VSCANGROUP
    • VSCAN
    • VSCANPROFILE
    • VSCANTEST

Depending on your operating system and environment, the output that you see may differ slightly from what is shown in this article.

Install the agent

The Deep Security Agent is installed with core agent functionality only. After the agent is installed on SUSE Linux Enterprise Server or Red Hat Enterprise Linux, you can enable protection modules on the agent. At that point, the plug-ins required for the protection modules will be downloaded and installed.

  1. Go to the Deep Security software download page and download the agent package for your OS.
  2. Install the agent on the target system. You can use rpm or zypper, depending on the OS. In this example, rpm is used by typing:
    rpm -ihv Agent-Core-SuSE_<version>.x86_64.rpm
  3. You should see output similar to what's shown in this example, which indicates that the agent installation is complete:

    SAP agent install

You can also deploy the agent using a deployment script generated from Workload Security.

The agent is now installed on the SAP server but no protection modules are active. To enable protection, you need to add the SAP server to Workload Security.

Add the SAP server to Workload Security and activate the agent

To add the SAP server, open the Workload Security console and on the Computers tab, click New. There are several ways to add the server, including synchronization with Microsoft Active Directory, VMware vCenter, Amazon Web Services, or Microsoft Azure. You can also add the computer using an FQDN or IP address. For detailed instructions, see About adding computers.

The status of your instance will be either Unmanaged (Activation Required) or Unmanaged (Unknown). Next, you will need to activate the agent before Workload Security can assign rules and policies to protect the computer. The activation process includes the exchange of unique fingerprints between the agent and Workload Security. There are two ways to activate the agent: agent-initiated or manager-initiated.

Manager-initiated activation: This method requires that Workload Security (the manager) can connect to the FQDN or the IP of the agent via the agent's listening port number for heartbeats. This can sometimes be difficult due to NAT port forwarding, firewall, or AWS security groups. To perform manager-initiated activation, go to the Computers tab in the Workload Security console, right-click the instance where the agent is installed and click Actions > Activate. If you use manager-initiated activation, we strongly recommend you also Protect Deep Security Agent from unauthorized managers.

Agent-initiated activation: The agent-initiated method requires that the Deep Security Agent can connect to Workload Security.

You will also need to enable agent-initiated activation from the Workload Security console, by clicking Administration > System Settings > Agents and selecting Allow Agent-Initiated Activation.

Next, use a locally-run command-line tool on the Deep Security Agent to initiate the activation process. The minimum activation instruction contains the activation command and the Workload Security URL (including the port number):

dsa_control -a dsm://[managerurl]:[port]/

where:

  • -a is the command to activate the agent, and
  • dsm://managerurl:443/ is the parameter that points the agent to Workload Security. ("managerurl" is the URL of Workload Security, and "443" is the default agent-to-manager communication port.)

The manager URL is the only required parameter for the activation command. Additional parameters are also available. (For a list of available parameters, see Command-line basics.)

To confirm the activation:

  1. In the Workload Security console, go to the Computers tab.
  2. Click the computer name and then click Details and check that the computer's status is "Managed".

Assign a security profile‌

At this point, the status of the agent is Managed (Online) but there is no protection module installed. This means that the agent and Workload Security are communicating but the agent is not using any configuration.

There are several ways to apply protection. In this example, the configuration is done directly on the SAP instance by activating anti-malware and SAP and assigning the default Scan Configurations.

  1. In the Computer or Policy editor, go to Anti-Malware > General.
  2. In the Anti-Malware section, set Configuration to On (or Inherited On) and then click Save.

    Anti malware configuration

  3. In the Real-Time Scan, Manual Scan, or Scheduled Scan sections, set the Malware Scan Configuration and Schedule, or allow those settings to be inherited from the parent policy.

  4. Click Save. The status of the anti-malware module changes to Off, installation pending. This means that the agent is retrieving the required module from Workload Security. For this to work, the client needs to access the Relay on the relay's listening port number. A few moments later, the agent should start downloading security updates such as anti-malware patterns and scan engines.
  5. In the Computer editor, go to Settings > Scanner.
  6. In the SAP section, set Configuration to On (or Inherited On) and then click Save.

After status of the agent changes to Managed (Online) again and the anti-malware and Scanner (SAP) modules are On, you can proceed with the SAP configuration.

Scanner on

Configure SAP to use the agent

The agent is now up and running and is able to scan the file system of its operating system. Next, we need to make the agent aware of the SAP application server. To use this, we must create a virus scan adapter inside the application server. The virus scan adapter must be part of a group. After the virus scan adapter and virus scan group are created, we can use virus scan profiles to configure what to scan and how to behave.

These are the required steps:

  1. Configure the Trend Micro scanner group
  2. Configure the Trend Micro virus scan provider
  3. Configure the Trend Micro virus scan profile
  4. Test the virus scan interface

The virus scan group and the virus scan adapter are both global configurations (client 00). The virus scan profile must be configured in each tenant (client 01, 02, etc.).

Configure the Trend Micro scanner group

  1. In the SAP WinGUI, run the VSCANGROUP transaction.

    VSCAN group

  2. In Edit mode, click New Entries. Create a new scanner group, specifying a group name in the Scanner Group area and a description of the scanner group in the Group Text area.

    Edit SAP VSCANGROUP

  3. Clicking Save or leaving the edit mode will prompt you to commit a "workbench request". In this example, a new workbench request is created to keep track of all the VSI-related changes:

    Save SAP VSCANGROUP

The next step is the actual configuration of the VSI integration. It is called a Virus Scan Adapter.

Configure the Trend Micro virus scan provider

  1. In the SAP WinGUI, run the VSCAN transaction.

    SAP VSCAN transaction

  2. In Edit mode, click New Entries. Creating a new entry displays a prompt in which the configuration of the VSI-certified solution takes place. In this example, the following configuration parameters are set:

    SAP VSCAN edit

    Setting Value Description
    Provider Type ADAPTER (Virus Scan Adapter) Automatically set (default)
    Provider Name VSA_<host name> Automatically set, serves as alias
    Scanner Group Select the group that you configured earlier All previously created scanner groups, which you can display using the input help
    Status Active (Application Server) Automatically set (default)
    Server nplhost_NPL_42 Automatically set, hostname
    Reinit. Interv. 8 Hours Specifies the number of hours after which the Virus Scan Adapter will be reinitialized and load new virus definitions.
    Adapter Path (Linux) /lib64/libsapvsa.so Default path
    Adapter Path (Windows) C:\Program Files\Trend Micro\Deep Security Agent\lib\dsvsa.dll Default path

  3. When you click Save or leave the edit mode, there is another prompt to pack this into a workbench request. After confirming, click the Start button. The Status light will turn green, which means the adapter is loaded and active:

    Save vscan

At this point, the VSI configuration is nearly finished. The application server is now ready to process file transactions using a virus scan provided by Trend Micro.

Configure the Trend Micro virus scan profile

  1. In the SAP WinGUI, run the VSCANPROFILE transaction, then select the SAP operation that requires virus scan. For example, check the "Active" checkbox for /SCET/GUI_UPLOAD or /SCET/GUI_DOWNLOAD and then click Save.

    SAP VSCAN profile

  2. In Edit mode, click New Entries. The virus scan profiles will define how specific transactions (file uploads, file downloads, etc.) are handled corresponding to the virus scan interface. To have the previously configured virus scan adapter used in the application server, a new virus scan profile needs to be created:

    Edit VSCAN profile

  3. In the Scan Profile box, enter "Z_TMProfile" and select the Active, Default Profile, and Evaluate Profile Configuration Param check boxes.

  4. While still in edit mode, double-click Steps to configure the steps:

    VSCAN profile steps

  5. Click New Entries.

  6. The steps define what to do when the profile is called by a transaction. Set the Position to "0", Type to "Group" and the Scanner Group to the name of the group that you configured earlier.
  7. After clicking Save or leaving the edit mode, you will eventually receive a notification about an existing virus scan profile, /SCET/DP_VS_ENABLED. You can ignore this notification because the profile is not active and is not used. After confirming this notification, you will be asked to pack this configuration in a "customization request". Creating a new request will help keep track of the changes that have been made:

    Save SAP VSCAN

  8. To create configuration parameters for a step, double-click the Profile Configuration Parameters node. Click New Entries and set the parameters:

    Parameter Type Description
    CUST_ACTIVE_CONTENT BOOL Check whether a file contains script (JavaScript, PHP, or ASP script) and block
    CUST_CHECK_MIME_TYPE BOOL Check whether the file extension name matches its MIME type. If they do not match, the file will be blocked. All MIME types and extension names can be exactly matched. For example:
    • Word files must be .doc or .dot
    • JPEG files must be .jpg
    • Text and binary files could be any extension (won’t block)

    See Supported MIME types.

  9. Double-click the Step Configuration Parameters node. Click New Entries and set the parameters:

    Parameter Type Description Default (Linux) Default (Windows)
    SCANBESTEFFORT BOOL The scan should be performed on the "best effort" basis; that is, all (security critical) flags that allow a VSA to scan an object should be activated, such as SCANALLFILES and SCANEXTRACT, but also internal flags. Details about exactly which flags these are can be stored in the certification. (not set) (not set)
    SCANALLFILES BOOL Scans for all files regardless of their file extension. disabled disabled
    SCANEXTENSIONS CHAR List of the file extensions for which the VSA should scan. Only files with the configured extensions will be checked. Other extensions are blocked. Wildcards can also be used here to search for patterns. * stands for this location and following and ? stands for only this character. For example, exe;com;do?;ht* => `*` means to scan all files. null ""
    SCANLIMIT INT This setting applies to compressed files. It specifies the maximum number of files that will be unpacked and scanned. INT_MAX 65535
    SCANEXTRACT BOOL Archives or compressed objects are to be unpacked enabled enabled
    SCANEXTRACT_SIZE SIZE_T Maximum unpack size 0x7FFFFFFF 62914560 (60 MB)
    SCANEXTRACT_DEPTH INT Maximum depth to which an object is to be unpacked. 20 20
    SCANMIMETYPES CHAR List of the MIME types to be scanned for. Only files with configured MIME types will be checked. Other MIME types are blocked. This parameter works only if CUST_CHECK_MIME_TYPE is enabled. (not set) (not set)
    BLOCKMIMETYPES CHAR List of MIME types that will be blocked. This parameter works only if CUST_CHECK_MIME_TYPE is enabled. (not set) (not set)
    BLOCKEXTENSIONS CHAR List of file extensions that will be blocked. (not set) (not set)

This configuration is per-client, so it must be done in each tenant of the SAP application server.

Test the virus scan interface

  1. In the SAP WinGUI, run the VSCANTEST transaction.

    SAP test VSCAN

  2. Every VSI-aware SAP application server also has a built-in test to check whether the configuration steps were done correctly. For this, an EICAR test virus (www.eicar.org) is packed in a transaction that can call a specific scanner. Not filling in anything will call the default profile, which was configured in the last step.

  3. Clicking Execute prompts a notification that explains what an EICAR test virus is. After confirming this, you will see how the transaction is intercepted:

    Execute VSCAN test

Infections shows information about the detected malware.

Content Information shows the correct MIME-type of the file.

The file name is always a randomly generated 7-letter alphabetic string followed by the virus scan profile name.

After this, there is an output about each step of the transaction:

  1. The transaction called the default virus scan profile, which is the virus scan profile Z_TMPROFILE.
  2. The virus scan profile Z_TMPROFILE is configured to call an adapter from the virus scan group Z_TMGROUP.
  3. The virus scan group Z_TMGROUP has multiple adapters configured and calls one of them (in this case, VSA_NPLHOST).
  4. The virus scan adapter returns value 2-, which means a virus was found.
  5. Information about the detected malware is displayed by showing Eicar_test_1 and the file object /tmp/ zUeEbZZ_TMPROFILE.
  6. The called default virus scan profile Z_TMPROFILE fails because step 00 (the virus scan group) was not successful and therefore the file transaction is stopped from further processing.

For a cross-check, there is also information about this "malware" event in the Workload Security console. To see the event, open the Computer editor and click Anti-Malware > Events.
