SAP FICO Authorizations
ACCESS CONTROL | AUTHORIZATION MANAGEMENT FOR SAP®
Far more damage, however, can be caused by too extensive authorizations. For example, an employee may be authorized to access data for which he or she is not authorized. In the worst case, criminal activity can cause economic damage. To prevent this, an authorization concept must be in place that describes how authorizations are to be created and assigned to users.
Access to this data is critical, since the hash values can possibly be decrypted using tools, thus enabling unauthorized logon to the SAP system. Since identical passwords are often used for different systems, the determined password may also be usable for downstream systems. The current or former hash values of the passwords are stored in the tables USR02, USH02, USRPWDHISTORY, USH02_ARC_TMP, VUSER001 and VUSR02_PWD. These tables can be accessed either via classic table access transactions such as SE16 or via database administration transactions such as DBACOCKPIT. The authorizations required for table access via database tools depend on the respective system configuration and should be verified via an authorization trace (transaction STAUTHTRACE), if necessary.

Roles can be cut so that, for example, they only have display or change permissions. Furthermore, it could be differentiated between customising, master data and movement data maintenance.
A mass rolling out of rolls is a very useful thing. It is also possible to use Excel-based data - as in the case of the outlined application case with eCATT - because it is a one-time action for the roles considered and SAP standard programmes are used in the background. However, ongoing maintenance of the permissions system, with continuous changes to roles and their detail permissions, requires the mapping of much more complex operations. An exclusive control over Office programmes should be well considered. This does not mean, of course, that there are not very good partner products for the care of roles. Simply verify that SAP standard procedures are used and that authorisation is managed in accordance with SAP best practices.
Authorizations can also be assigned via "Shortcut for SAP systems".
SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page: www.sap-corner.de.
Cybersecurity is a broad field.
The freeware Scribble Papers puts an end to the confusing paper chaos. The tool is also suitable for storing, structuring and quickly finding text documents and text snippets of all kinds in addition to notes.
How secure business data is in SAP depends largely on the assignment of authorizations and access options for a company's users.
