SMT1 Trusted - Trusting Connections
The digitization of businesses and the emergence of new technologies mean that admins have to adapt to constantly changing conditions. Currently, the following trends (which are becoming more and more evident in the market) can be mentioned:
User authentication is usually performed by entering a user name and password. This information is called user credentials and should only be known to the user, so that no third party can gain access to the system under a false identity. This post explains how a user's password protection can be circumvented and how to prevent it. SAP system legacy data The login data of a user, including password, are saved in the USR02 database table. However, the password is not in plain text, but encrypted as a hash value. For each user there are not only one but up to three generated password hashes. Different algorithms are used to calculate these values, but only the Salted SHA1 can be considered sufficiently safe. Table deduction USR02 The secure password hash is located in the fifth column of the pictured table deduction with the heading Password hash value. The corresponding data field in the column is called PWDSALTEDHASH. Weak Password Hash Risks You have a good and working permission concept that ensures that no processes or data can be manipulated or stolen. A potential attacker now has the ability to read out your database with the password hashes. The hash values are calculated using password crackers, which are available on the Internet at home, and the attacker now has a long list of user credentials. To damage your system, the user will now search for the appropriate permissions and perform the attack under a false identity. Identifying the actual attacker is virtually impossible. Check if your system is vulnerable too Your system generates the weak hash values if the login/password_downwards_compatibility profile parameter has an unequal value of 0.
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.

In the following dialogue, select a TADIR service and the programme ID "R3TR" and the object type "IWSG". Now you can select the OData service stored on the front-end gateway. Then switch to the Permissions tab to generate the current profile of the permission objects with the new Fiori permission. Once you have performed these steps, the treated role has the necessary permissions on the front-end side. Fiori Permission to call the OData service on the backend server Now go to the role maintenance in the PFCG on the backend server. Open the appropriate role in Change Mode. Now you can repeat the steps for the frontend as explained above. However, when selecting the TADIR service as the permission proposal, you now select the object type "IWSV". Here you can select the OData service of the specific Fiori application stored in the backend.
The default permissions to open and use a launchpad are the SAP_UI2_USER_700. The role for the administration is SAP_UI2_ADMIN_700. In the administration interface, the launchpad can be customised, so this permission should only be released to a few users for administration.
Tools such as "Shortcut for SAP Systems" complement missing functions in the SAP basis area.

So much information... how can you keep it so that you can find it again when you need it? That's what Scribble Papers is great for.
For this purpose, there is the RSMEMORY report.
