SAP Security in Transition - SAP HANA Permissions
Planning / Implementation
Reduce resources: depending on the agreement of the contract, you can ask for the service resources only when needed. This will save you some costs.
SAP Basis is the foundation of every SAP system. This page explains what is behind the term and what SAP Basis is responsible for in detail.
Some useful tips about SAP basis can be found on www.sap-corner.de.
Migration
This access method depends solely on the rights assigned to the user. System users: Users of this user group are comparable to SAP*. They act as administrator in the system. Therefore, they should be deactivated / set to inactive as soon as possible, as soon as the system operation is ensured. You should still be aware of the SAP ERP environment to address this security risk. In a HANA system, there are privileges instead of permissions. The difference is first of all in terms of terminology. Nevertheless, the permissions are assigned differently (directly / indirectly) via the assignment of roles. These are thus accumulations of privileges. As in older SAP systems, system users must be disabled and certain roles that already exist must be restricted. Compared to an SAP ERP system, small apps are allowed instead of large applications. In this case, attention should be paid to an individual authorisation. It should be a matter of course for users to have implemented secure password rules. Settings Securing the system also means securing the underlying infrastructure. Everything from the network to the host's operating system must be secured. When looking at the system landscape, it is striking that the new technology brings many connections that need to be secured. The SAP Gateway, which is responsible for the connection between backend and frontend, is also a security risk and must be considered. All security settings of existing and future components must be validated to HANA compatibility. Secure communication of connections is obtained when you restrict access where possible. Encryption of the data of a HANA system is disabled by default. Be sure to encrypt sensitive data anyway. Especially data that is archived. If an attack is made on your system, you should be able to run forensic analysis, so you should enable the audit log. Moreover, few users should have access to it.
SAP Basis is also known as module BC or application Basis. In this context, SAP Basis refers to all transactions, programs and objects that control the functions of the overall system. This includes, among other things, user and authorization management as well as the configuration of interfaces via RFC.
"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.
SAP GUI for Windows, SAP GUI for Java, Web Dynpro for ABAP (WDA) and SAP GUI for HTML ("Web GUI") are widely used.
To store all the information on the subject of SAP - and others - in a knowledge database, Scribble Papers is suitable.
The SAPSolution-Manager can also support this as a tool of SAP e.g. through the Guided Procedures.
