Data ownership concept
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.

To store all the information on the subject of SAP - and others - in a knowledge database, Scribble Papers is suitable.
Here we present different scenarios for the process of resetting passwords. In all scenarios, the user selects the system and the client in which a password is to be reset from a web page. Only systems and clients where this user already exists and assigned a permission should be displayed. An initial password is then generated and sent to the user's email address. Only if a user lock is set by false logins, the user must be unlocked. If an administrator lock is in place, the user should be informed accordingly. Before implementing self-service, consider the password rules set in your systems and the use of security policies. Because these settings allow you to control how passwords are generated in your systems. We recommend that you read the instructions in Tips 4, "Set Password Parameters and Valid Signs for Passwords", and 5, "Define User Security Policy".
Optimization of SAP licenses by analyzing the activities of your SAP users
Both solutions offer you the added value of centralised reporting of existing users, newly created users, and role assignments. You can also extend the integrated workflows of both solutions to HANA permission applications. This enables you to use the risk analysis of the SAP Access Control solution also in relation to critical HANA permissions.
In contrast to storing passwords in the form of hash values, the user ID and password are transmitted unencrypted during the login of the client to the application server. The Dynamic Information and Action Gateway (DIAG) protocol is used, which may look somewhat cryptic but does not represent encryption. In addition, there is no cryptographic authentication between the client and the application server. This applies not only to communication between the user interface and the application server, but also to communication between different SAP systems via Remote Function Call (RFC). So, if you want to protect yourself against the access of passwords during the transfer, you have to set up an encryption of this communication yourself.
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.
In many cases, such authorisation problems lead to a hidden compliance violation, because this means that the traceability of user actions in the SAP system is no longer guaranteed.
