Security Aspects for BSP 

It is important to consider security aspects when you create Web applications using the BSP programming model. Security functions are available both for when you create BSP applications as well as for when you operate them.

Security in AS-ABAP

For basic information about security aspects in an AS-ABAP system in which you are creating your BSB application, see Network Infrastructure and Security in AS-ABAP.

Note in particular the Configuration for SSL Support.
Furthermore, a function is provided for increasing performance in the case of multiple logons, namely the Logon Ticket Cache.

Certain Virus Scan Profiles are delivered by SAP in the standard system. A virus scan can be performed when uploading HTTP (see also Virus Scan Interface).

The Internet Communication Manager (ICM) receives the HTTP requests from the Internet and returns a response.

Logging on to BSP Applications

To access a BSP application, AS-ABAP uses the HTTP framework from the Internet Communication Manager (ICF), which provides functions for Logging on to the AS-ABAP.

Refer in particular to Activating and Deactivating Services. For security reasons, the only services that should be active in the HTTP service tree are those services that you really need. If, however, you activate nodes at a higher level, this means that the whole part of the service tree below this level is completely open and is therefore not secure if an anonymous user is defined, for example.

For a list of the services that have to be activated depending on their usage in note 517484.

To create logon procedures for your BSP application there is a simple procedure for developing and configuring the system logon. Security functions are included in this procedure. For more information see System Logon.

Accessing a BSP Application

A browser accesses your BSP application using HTTP or HTTPS. The most important aspects are summarized in Accessing a BSP Application.

Furthermore, you can determine that your BSP should always be accessed using HTTPS. For more information about defining the transmission options, see the description of the Properties of a BSP application.

Security Risk List

A white list infrastructure in the HTTP framework fends of XSS attacks: Security Risk List.

URL Generation
