SAP Basis - operation, structure and definition
SAP Business Server Pages
On the one hand, staff clerks (or other personnel officials) should be able to carry out their important work. On the other hand, the protection of personal data of one's own employees is one of the most important tasks of the authorisation system. Any mistake in this area can cause the company's data protection officers to wring their hands over their heads. For this reason, tools are currently being developed to provide security and visibility in the HR permissions area. The basic idea is a clear overview that shows which data certain users in the SAP system can access. Based on this, automatic checks can be developed, which run in the background and regularly check whether critical gaps have been created by changes to the permissions in the HR area. The use of such a tool can create more security, especially in the HR authorisation environment. In addition, the possibility of the overview function is very pleasant and relieving for all involved. Read more This blog post is intended to show what is already possible in the field of Security Automation. The topic will accompany us more and more in the SAP area in the next few years. Therefore, it is recommended to start thinking about how your company is prepared for security automation. If you are interested in setting up and preparing a company outside the security area, I can recommend the book 'Consulting Y' by Ferdinando Piumelli (Managing Director of mindsquare GmbH). In this book, Mr. Piumelli describes his observations and experiences of digital transformation as a strategy consultant for leading DAX30 companies. In doing so, he is focusing on the near future, which, in the spirit of the digital revolution, will have a major impact on the world's large companies and economy.
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.
Is that all there is to know about SAP Basis?
In transaction PFUD (see image above), you can perform the user match manually for all roles (or selected roles). You can choose between the matchup types Profile Matchup, Matchup of Indirect Assignments from Composite Roles, and Matchup HR Organizational Management. According to SAP documentation, the matchups differ as follows: Profile Matchup: "The program compares the currently valid user assignments of the selected single roles with the assignments of the associated generated profiles and makes any necessary adjustments to the profile assignments. Matching indirect assignments from composite roles: User assignments to composite roles result in indirect assignments for the single roles contained in the composite role. This match type matches the indirect assignments of the selected single roles to the user assignments of all composite roles that contain the single roles. If the selection set contains composite roles, the comparison takes place for all single roles contained in it. HR Organizational Management comparison: This comparison type updates the indirect assignments of all selected single and composite roles that are linked to elements of HR Organizational Management. The HR adjustment is inactive and cannot be selected if no active plan version exists or if a global deactivation has been made by setting the Customizing switch HR_ORG_ACTIVE = NO in table PRGN_CUST. Furthermore, the option "Perform cleanup" is interesting, which can be selected independently of the three adjustment types and does not refer to the role selection. The Perform Cleanup function can be used to remove residual data that resulted from incomplete deletion of roles and the associated generated profiles.
With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.

Even dialog systems are no longer in operation only from 8 a.m. to 6 p.m., but between 7 a.m. and 10 p.m. or longer.
