Define security policy for users
Authorization concepts in SAP systems
Object Privileges: Object Privileges are SQL permissions that control access to and modification of database objects (as a whole). The type of object (table, view, procedure) determines which database operations can be authorised. Database operations include SELECT, UPDATE, ALTER, DROP, and DEBUG.
Typically, users access a table's data through applications rather than directly. If so, you should take precautions and restrict access to sensitive data. End users typically do not access table-level data directly, but the data is displayed in business applications and their display is restricted in context by means of entitlement checks. However, there are cases where generic access to tables via the SE16, SE16N, SM30, SM31 or SM34 transaction is required for administrators, key users, verifiers, etc. For example, a verifier should have read access to all customising tables. However, you do not want to display security-related tables. Key users should be able to access certain reports regularly, but only read information relevant to their work. There are several ways to restrict access to tables by using table tools. This means that users can only access tables or table contents that they want to see. However, we would like to point out that the granting of permissions for these tools in the production environment is considered to be critical to security, since it is very easy to allow access to large amounts of sensitive data in the case of erroneous or excessive permissions. Therefore, only apply these permissions in a restricted way.
Schedule PFUD transaction on a regular basis
Even the best authorization tools cannot compensate for structural and strategic imbalances. Even a lack of know-how about SAP authorizations cannot be compensated for cost-effectively by means of tools.
You can greatly facilitate the maintenance of permissions in controlling by defining the RESPAREA field as the organisational level, and thus using your cost centre and profit centre hierarchies. In the SAP system, you can define cost centre hierarchies and profit centre hierarchies. For example, they can map the expiration organisation or a matrix organisation in your company. To facilitate the mapping of permissions for the controlling reports, you can grant permissions to nodes in those hierarchies. You can do this by assigning permissions through the RESPAREA field, which is used in certain authorization objects in the controlling. We would like to facilitate the creation of roles for these permissions by explaining to you which activities are necessary in advance to define the RESPAREA field as an organisational level.
The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".
The audit result lists the vulnerabilities by priority, with a high priority combined with a high hit safety of a finding and a low priority combined with low hit safety.
At www.sap-corner.de you will also find a lot of useful information on the subject of SAP authorizations.
You can do without taking obsolete profile data into account by adding the correction from SAP Note 1819126 and then setting the REC_OBSOLETE_AUTHS customising switch to NO in the table PRGN_CUST.
