SAP SM37: How to monitor a background job?
Often you are obliged to perform a migration. There are various reasons, such as legal requirements or preparatory measures for an S/HANA conversion. We are happy to support you in your decisions.
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.
SAP System Analysis
Automation of processes In an IDM, IT business processes, creating, modifying and deleting a user are defined centrally by means of a unique set of rules. All the necessary steps are then completed using automated workflows. User administration no longer has to be administered separately for each system, but only in a single point of administration. Data Consistency Employee data is created only once in a leading system in an IDM architecture. All attached systems use this data in their user management on demand. In a change of department or a new activity, permissions are automatically adjusted. Security and Documentation In a centralised user administration, users can be locked down efficiently on all systems or access rights can be changed. The connection to the personnel process automatically initiates the change process as soon as the master record is adjusted in the Human Resources Department. Documentation solutions can also be used to archive all processes without any gaps. This creates transparency which also facilitates the detection of a functioning and secure authorisation concept during audit tests. Requirements for IDM systems People get electronic identity attributes describe the role of the person Quality requirements Reliability: Abuse prevention Readability: Documentation and logging Failover: Back-up systems in compliance with legal requirements Data Protection Act What should be taken into account in application processes? When implementing an IDM and also in the day-to-day operation of an IDM, there are certain things that should be taken into account when applying. I have summarised the most important points in the form of a checklist.
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.
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.
In order for the stored business logic of an application to be executed correctly, the executing user must also have the necessary permission objects in the flow logic of the OData services in his role. If Authority Checks are performed here, e.g. to query or change data on the backend server, the corresponding role must be authorised. These permissions are expressed in a role by permission objects, as in any ABAP report. If you follow these steps, your Launchpad users should have the Fiori permissions necessary to launch the launchpad, view all relevant tiles, and run the specific apps with their business logic.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
In view of his impasse, he opts for a drastic measure.
To do this, use the report CLEANUP_PASSWORD_HASH_VALUES.
