Data Security in SAP NetWeaver ILM System Connections

System Landscape Components

The SAP NetWeaver ILM system landscape includes the following main components:

Application system (AS ABAP)
WebDAV-Server on which ILM stores are set up
System on which the service for the control of ILM stores runs
Since two different services are available for controlling ILM stores, two system landscape variants are possible.
- The Storage and Retention Service (SRS) runs either in the application system (AS ABAP) or on a separate AS ABAP.

- XML Data Archiving Service (XML DAS) runs on an AS Java.

Data Security for System Connections

Communication between systems takes places with HTTP connections.

HTTP Connection between Application System and ILM Store Service

If the service (SRS or XML DAS) runs on a separate system, you need an HTTP connection from the application system to that system. You use an HTTP or HTTPS protocol. The configuration of the HTTP connection is described in the documentation for the relevant service.

If you use the local SRS service of the application system to control ILM stores, you do not need a connection.

HTTP Connection between ILM Store and ILM Store Service

The ILM Stores that are set up on a WebDAV server need to be connected to a service with an HTTP connection. A WebDAV protocol, which is an enhancement of the HTTP protocol, is used. The configuration of the HTTP connection is explained in the documentation for the relevant service.

User Authentication for System Connections

The application system can access the service with an HTTP connection only if the connection is made by a user who has the corresponding authorizations. This user must be created in the system on which the service run and entered in the data for the HTTP connection.

In the case of a connection from the service to the WebDAV server, user authentication is performed according to the options offered by the WebDAV server. SAP supports basic authentication with a user of the WebDAV server (with password) as well as with SSL.
