Remove weak password hashes from the system: Only updating the profile parameter does not provide you with the necessary security. There are still many weak hash values in your database that can be used to attack your system. These must be completely removed from the database. To do this, use the report CLEANUP_PASSWORD_HASH_VALUES. To do this, call the transaction SA38 and enter the name of the report in the input field. Run or F8 executes the programme and cleans your database Report CLEANUP_PASSWORD_HASH_VALUES This programme removes the outdated hash values across all clients.

Especially in larger companies, which also have multiple locations in different countries, it is often necessary to grant different employees the same permissions for different levels of organisation, such as accounting circles. In order to make maintenance and maintenance of the system easy in such a situation, it is useful to set the inheritance principle for SAP permissions. How does SAP Permissions Inheritance work? An inheritance is always about a master object passing certain properties to a derived (sub) object. Therefore, these properties do not need to be maintained several times. Also, changes to the master object are passed directly to the derived objects. This allows easier maintenance and drastically minimises the error rate. In the case of SAP Permission Inheritance, the required permissions are bundled in a Upper or Master role. Only the organisational levels have to be maintained in the roles derived from them. The permissions are automatically pulled from the master role. Create Inheritance for SAP Permissions The following shows how to create and use inheritances for SAP permissions. This requires only two steps: Creating a master role and defining derived roles. Step 1: Create a master role Inheritance always requires a parent role, because all properties are inherited from it. If this role, in which all shared permissions are bundled, is missing, the first step is to create this master role. To do this, open the PFCG transaction and enter the desired name of the master role in the Name field. It is possible to identify master and derived roles by using naming conventions. The "Single Role" button will then be used to create the desired role. In the following example I create the master role "findepartment_r".
STAD SAP Workload: Business Transaction Analysis
In order to have some advantage in terms of new SAP technologies, suitable PoCs (Proof of Concepts), research and pilot projects must be initiated to build know-how and evaluate boundary conditions or feasibility. Furthermore, this serves the evaluation of new business models by the underlying technology in collaboration with the respective business unit.
New risks in SAP HANA: In addition to the known risks, there are also new risks from the use of SAP HANA. A very good example are frequently used web applications that represent something new in the SAP area. In contrast to an SAP ERP system, HANA systems consist mainly of web applications, which were considered optional in the previous versions. These web applications can be found by various search engines on the Internet. This also applies to SAP Portal or Netweaver. There are URL schemes that help locate the system. This also applies to other SAP systems that use Web applications. This makes the new technology vulnerable to typical web attacks. SQL Injection, ABAP Code Injection, or XSS are all included. All risks known for a normal SAP system also apply to a SAP-HANA system. The data is stored unencrypted in RAM. Only then does the system gain this speed advantage. This results in risks such as a read-out by memory scraping malware. These pick up data in memory. Encryption costs performance, so it is not used by default. Especially during a migration HANA runs in a parallel system, therefore at least one new system comes to your landscape. Also note: HANA has its own tools and settings that need to be known and configured. The bottom line is that the system simply needs more attention when operating. Many settings often result in more errors. Three - points - HANA Security Plan 1) Roles and permissions In a previous SAP system, roles and permissions are certainly one of the main pillars of a secure system. Roles and permissions work differently in a HANA system. There are two types of users: 1) Default (limited): With this type of user, there are different access methods to the database. For example, the JDBC or HTTP technologies are used to give two examples.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
This requires only two steps: Creating a master role and defining derived roles.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
Even for companies that hand over the operation of the SAP Basis to an external service provider, there are often still tasks from the environment of user and authorization management at this point.
