We recommend that you enable virus scanning if you plan to allow files to be uploaded to the Web shop. For Web Channel 1. If you have not installed a virus scanner for the J2EE server, you must disable the virus scan in the application Web descriptor for the component to function.

This is not recommended for productive usage. No No virus scan is performed. Yes The input field Virus Scan Profile is available where you enter the virus scan profile that is used as the default Web Channel virus scan profile. The Web descriptor parameter com. If this parameter is set to true, then the secure cookie attribute is set. This setting applies to all application cookies that support this parameter. A list of these cookies can be found below. To improve security it is recommended to set the attribute.

Only Attribute for Web Channel applications. If this parameter is set to true, then it applies to all application cookies that support this parameter. For more information, see Session Security Protection in this guide. The below table shows which Web Channel cookies support these attributes. To make the protection more secure a secret can be specified in the Web descriptor using the context parameter com.

If you change the value of parameter com. CookieHashSalt for a deployed and active application, old cookies do not work. The cookie protection is currently available for the recoverCart cookie. The user session is terminated shortly after this condition is detected. Note that the session timeout limits the chances an attacker has to guess or steal an existing user session and to use a valid session ID from another user. For this reason, we strongly recommend that the Web Channel administrator uses third-party tools to protect against these types of attacks.

This is especially true if any redirect to external service providers, for example payment service providers, is made. This is done by uploading a zip file containing the application configuration files. The functionality contains a protection against ZIP bombs. This instructs the browser not to provide the autocompletion functionality for this component.

When you integrate third-party payment service providers, we recommend that you comply with your company security guidelines. Following the recommendations given in SAP Note , proceed as follows: 1.

The data flow is then as follows: The back-end system sends the data to the defined SSH forwarding port. All communication between the systems is encrypted using SSH. You need to maintain the used Web Channel destinations as described in the section Communication Destinations of this guide. In addition, the certificate used by the UME to create SAP logon tickets or assertion tickets must be known by the back-end system. To add or remove WECB applications from the list of available applications, you must change the Java system property wcb.

Several entries can be separated by a comma. To prevent unauthorized preview operations from being carried out in the applications URL, previewed applications are enhanced with a unique URL parameter value known as a token. During the creation of the URL, the token is generated and stored in the Java database.

The lifetime of this token is defined in milliseconds using the context parameter in the web. The default token lifetime is one hour. When the Web Channel application preview is called, it is checked first to ensure that the token for the given appId and configId is available and valid.

In case of an incorrect token, a TokenNotValidException is triggered. Otherwise, the preview is started. The URL parameter wec-configid is only considered in preview mode. In all other cases, the active online configuration is started. WECB users must use password change functionality from the UME or from the back-end system, depending on the user management configuration.

We recommend using UME logon to improve security. Here you can define the authentication and user identification type to use, specify self-registration settings, select e-mail. This process can be set up as single page registration, or as a guided activity. Depending on the configuration, the user account is either active immediately after registration allowing the user to log on right away , or must be activated following registration.

In the latter case, an activation mail is sent to the users e-mail address. This e-mail includes a URL containing an activation key. The user has to open the URL to activate the user account. It is also possible to define a validity period for the activation key. The validity of the activation key is defined in days. This functionality is enabled in the User module in Web Channel Builder. When users forget their password, they can generate a new one. To do so, they must provide data to identify themselves.

The type of data to be provided is selected in the User module. A security question can also be specified. The system sends the new password to the user's e-mail address.

When the user logs on with the new password, they must immediately change it. The user in this scenario works on an anonymous technical user an SU01 user , and a reference business partner. The name and address of the guest user is only required during checkout.

To avoid prolonged system resource allocation, enable the fast session timeout feature. Due to the fact that the guest user scenario does not use authentication, the scenario is potentially vulnerable against session fixation attacks.

We recommend deactivating URL session rewriting. Web Channel user management enables the assignment of a user group that is used for user creation through self-registration and user administration. The user group must be specified in the configuration settings for the User module in Web Channel Builder. To authenticate this confirmation e-mail, a digital signature can be used. Since digitally signed e-mails are user-dependent, you can decide if you want to authenticate your emails.

Therefore, the user profile of this technical user needs to be adapted in transaction SU The sent e-mails are classified as Confidential by default. This ensures that an administrative user is not able to read the sent e-mails in transaction SOST. Since SAP does not deliver proprietary tools to digitally sign e-mails, you need to use third-party tools. It is mandatory to restrict the access to the administration pages from the Internet.

This should be done by HTTP proxy or a reverse proxy. Access to administration pages is limited by security roles. This allows customers to recover shopping cart contents if, for example, the session terminates unexpectedly.

A persistent recoverCart cookie is created to retrieve the anonymously collected shopping cart if it was not posted. If a customer computer is used by different users with the same user account, the cookie is shared by all these users.

If JavaScript is disabled on the browser, the application may not work as expected. This functionality cannot be deactivated. JavaScript and CSS can be outsourced to an external server, not necessarily running with the same protocol of the Web Channel application. As a result, a security warning popup appears when several data sources are not opened from the same protocol.

To access the fields, choose Details of the active configuration Modules and open the uicomponentconfig link. The fields are located on the Settings tab. We recommend you create a robot. These request parameters cannot be changed once a session has started. Whenever an attempt is made to change critical request parameters while a session is running, the system displays an error page to the user.

By default, changing the Web Channel application ID parameter, wecappid, would result in the system displaying an error page. However, you can adjust the parameter value in such a way that a change can be permitted without generating an error. To do so, specify the following context parameter in the web. If enabled, the current session is invalidated and the new URL is allowed. If disabled, error page is shown that wec-appid cannot be changed within the session.

Specify the project stage as Production. The project stage can be used to set up the current state of the Web Channel application in a typical product development life cycle. Set the request parameter javax. This is normally only used to test in productive mode in the development and test phase.

Config Tool Set Java system parameter com. Start the configtool. Select the instance on the navigation tree and the VM parameters on the right detail pane, then select the System tab. Create a new parameter with the name com. Restart your application.

Web Descriptor Set the context parameter javax. Do not assign the authorizations to use the parameters to the normal service and internet user roles. The authorization should be granted using a special role that can be assigned to users in special cases for instance if application support is needed. If the project is in production mode, the system parameter wec. The parameter is set to False by default. We recommend setting the parameter to False in productive mode.

In this mode the parameter should only be activated in exceptional cases, such as when application support is required. The exception hierarchy is shown in the following diagram:. You can map exceptions to a dedicated error page of your choice. Whether you do this for every servlet filter exception or to a parent exception depends on your scenario.

Mapping is performed in the web. When modifying help texts, we advise against entering HTML code that allows, for example, crosssite scripting attacks. Compliance with this standard is relevant for companies processing credit card data. Refer to the security guide for your back-end system for information about implementing payment card security, and the steps required to comply with the PCI-DSS.

This trace obtains the information for a particular session, and is used by developers or by support personnel.

The log location is set to com. Please note that session tracing only functions in a non-clustered environment where no load balancing takes place. This means that Web Channel applications can only be deployed to a single instance with one server node.

To switch the trace on, perform the following steps: 1. Enter the credentials of a user who is authorized to use the admin area. The homepage of the admin area is displayed. Select the tab Session Logging. From the list of available Web Channel applications of the deployment unit, you can now select the Web Channel application for which session logging shall be performed.

You can also activate session logging of excluded locations, if required. Follow the instructions on the Session Logging page. After having stopped the trace by clicking the button, a link appears where you can download the log file. To ensure that sensitive data, such as credit card numbers and back account data, are not traced, you can turn off tracing for a given component. This is done using a UI component parameter called trace.

When set to False, the trace of the UI component is prevented, and the information that would have been traced is replaced by default text, such as Component attribute TRACE is set to false. Debug trace is prevented.

OData was initiated by Microsoft to provide a standard for platform-agnostic interoperability. OData is a Web protocol for querying and updating data. It is easy to understand and extensible, and provides consumers with a predictable interface for querying a variety of data sources.

No Web services currently exist to create Web service users. Furthermore, Web services do not support password changes, meaning that Web services cannot handle initial or expired passwords. To create users and perform password changes, access the user management functionality offered by the User Management Engine UME or by User Management transaction SU01 in the back-end system.

The logon policy is valid in Web Channel for Web services and Web applications,. For this reason, the policy that you select must support both authentication processes.

Authentication Required. For Web services that require authentication, set the authRequired attribute to true in the wsconfig. If authentication is required but no user credentials are provided, the system returns a Unauthorized HTTP status code. If authentication is required and the incoming Web service request is not secure, the system returns a Forbidden HTTP status code.

Authentication Servlet Filter. The system performs the authentication process using the servlet filter class WebServicesAuthenticationFilter. The servlet filter class must run after the WebServicesSessionInitializationFilter, because the servlet filter class requires a Web Channel Web service session context.

We strongly recommend that you keep the authentication filter activated. Basic Authentication. Basic authentication is supported as specified in RFC The WWW-Authenticate header is not added to the response. Measurements are taken to enable a secure storage of the client certificate on the client side, for example on a mobile device.

Single Sign-On. Set the Policy Configuration setting in the Users module in Web Channel Builder to ticket or to an authentication stack that supports single sign-on mechanisms. Depending on the project stage, the system sends detailed error information, including stack traces, to the Web service consumer.

To prevent any information disclosure, we recommend that you set the project stage to Production in productive mode. You can locate Web service traces by filtering within the Java package com. You can write Web service requests and their responses into the trace file. Since both requests and responses can contain sensitive data, the caller needs to explicitly allow them to be written; you do this by passing the wec-debug parameter either as URL or header parameter. Furthermore, special authorization is required to use the wec-debug parameter.

To enable the debug trace in the log configuration, and to filter all request and response traces in the log viewer, you can use the following location: com. The Web service framework provides a proper initialized environment for Web service development.

Beneath application scoped framework objects, which are initialized during bootstrap of the application or by lazy load mechanism, the framework also creates session-based objects, the lifetime of which is restricted to the HTTP session.

To determine a Web service application and its application-based configurations and module definitions, an ID is required. To ensure that the called application is configured for Web service runtime scenarios, the system uses the method checkIfRuntimeScenarioIsValid.

Stateful Session Support. Web Channel framework allows you to keep the state. In case of stateful session, the WecSession object is stored in the HTTP session, and the session is not destroyed until the ReleaseState service operation is called or the session times out. You can enable stateful support using the Java system property wec.

If the system property is set to true, you can initiate stateful behavior by calling the service operation KeepState. The two system service operations are only visible in the metadata and available to be run if the Java System Property is enabled. If you use security constraints to control specific HTTP verbs, you must take into account the fact that verb tampering could be used to bypass Web authentication and authorization. After you create security constraints, configure Web Services to require authentication.

Special care must be taken if no authentication artifacts are provided for the Web services, as this causes the Web container to take over the authentication process.

Use authorization tracing to determine the required authorizations. For more information, see the following section, as well as the Authorization chapter in this guide. External services created for remote function calls triggered by Web service functionality are identified by the additional character sequence WS in the external service name. You must implement your own protective measures. The following table provides an overview of the measures to perform to ensure Web Channel application security.

Topic Security Measure Details. Set up a secure network topology using firewalls and reverse proxies. If using delegated user administration, do the following: qyFNd In the relevant Customizing activities, maintain the user roles that can be assigned.

Jw Web Channel applications switch to HTTPS only when authentication takes place Based on the scenario you select, specify parameters for session security protection. Disable URL session rewriting. Enable virus scanning by doing the following: Jw Set up an external virus scanner and ensure that it is also enabled on the J2EE server.

The following table provides an overview of the most important document changes: Version Date Description 1. The following table provides an overview of some attack scenarios and references to subsections that contain details on how to protect your application: Attack Scenarios Attack Type Description Relevant Subsections Broken access control Authenticated users are not required to perform User Administration and restrictions on the activities.

Contact Scenario In the contact scenario, the Internet user is linked to a business partner that represents a contact person for one or more customers. Creating Web Shop Customers You can create Web shop customers using either tool-based or manual methods. Maintaining Web Shop Customers The table below shows the tools that can be used to maintain the user part of an Internet user. NOTE Create your own user roles as described in Authorization Proposals in this chapter, and specify the authorization values according to your needs.

User Roles for Development, Testing, and Support Specific authorizations are used to control Web Channel functionality that is useful in the developing and testing phase, or to provide support in the productive phase. Guest User Scenario In the guest user scenario, no explicit user authentication takes place and all actions are performed by the technical service user.

In all other cases, the prefix is TU technical user. NOTE If different authorization levels are needed, you must create several roles with different authorization values. User who is currently logged on Used for stateful communication with the back-end system Used for stateful connection for LORD scenario to maintain additional sales document Used for connections to the application server that has called the IPC application for pricing information.

CAUTION As there are potential security risks in using this approach, we strongly recommend that you ensure that this solution is feasible for you. NOTE If a Web shop customers computer is used by different users with the same user account, the cookie is valid for all of these users. NOTE If you change the value of parameter com. NOTE If a customer computer is used by different users with the same user account, the cookie is shared by all these users.
