The SAP Identity Management System (IdM) enables centralised user and permission management in a heterogeneous system landscape. By using an IdMSsystem, manual processes can be replaced by automated workflows that are mapped and administered centrally. Examples of scenarios: 1) User and Authorisation Management 2) ESS/MSS for the management of personnel data 3) Audit and monitoring for the verification of compliance with legal regulations What should be taken into account, however, if you want to introduce an Identity Management System? In this contribution, I would like to highlight fundamental points that need to be clarified before the introduction.

Basically, an excellent IT knowledge is required. In addition, SAP administrators must of course be particularly competent in this area and be able to deal confidently with all issues relating to SAP solutions. Since they often also work in international companies, it is an advantage if they have a very good command of written and spoken English.

In this article on SAP Security Automation I would like to take a look at the future of automated processes in the SAP Security area. For many companies, the topic of security automation still offers a lot of potential in terms of time savings and process optimisation. Our daily work environment offers numerous tasks that could be handled excellently automatically. For this reason, in this article I present two of the possibilities that already exist in the broad area of security automation. Security Automation via SAP Security Check The first option of Security Automation, which I want to introduce here, is the automatic verification of the existing permissions. Have you ever wondered who has critical permissions in your SAP system? And have you ever tried to do this by hand? Depending on the level of expertise and experience of the privilege administrator, this is a time-consuming work. If an audit is also announced and the SAP system is to be checked for critical permissions and segregation of duties, then it is very difficult to meet all requirements and secure the eligibility landscape in this respect. For this reason, various vendors provide solutions to automate the verification of the permission system with regard to critical permissions and segregation of duties using tool support. This allows permission administrators to use their valuable time to correct the errors rather than just looking for them. For example, we use a tool that runs through the verification of over 250 rules. We then get an evaluation of which rules are violated and which points are correct. A simple example of such rules is the use of the SAP_ALL profile. Another would be to grant the jump permission in debugging (S_DEVELOP permission object with the ACTVT = 02 field). These are two relatively simple examples of Security Check tools' rulebook. In addition, queries are also made, which are located in the field of Segregation of Duties. Using this tool allowed us to move from manual validation of critical permissions to an automatic process.

For example, many customer ABAP programs work by uploading or downloading data. There are potentially large security gaps here that allow access to server data. In addition, the widespread direct invocation of operating system commands that are not covered by a self-programmed authorization check is a major problem. Even though classic SQL injection, i.e., the entry of extended SQL commands, is a potential security vulnerability, it occurs rather rarely in SAP systems. More widespread is the unintentional dynamization of SQL calls because input parameters are not sufficiently checked. The need to check all in-house developments internally for such security vulnerabilities before they are delivered in SAP's own code has led to the development of the SAP Code Vulnerability Analyzer tool.

"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.

The website www.sap-corner.de offers many useful information about SAP basis.

You cannot insert an FCS support package in a non-FCS system (official state of delivery).

This effect made it impossible to establish a trustworthy, decentralised digital currency by 2008.
