Preparation of full access to SAP systems and solutions in case of disasters (High Availability/Disaster Recovery)
Understanding the structure and functioning of the system is particularly important for IT administration. It is not for nothing that "SAP Basis Administrator" is a career field in its own right. Instead of data and application development, the focus here is on providing the software environment on which the company's tools are created. SAP Basis is therefore comparable to the server and platform infrastructure and its administration in companies - as distinct from application and web development.
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:
SQ01 Maintain SAP Query
In the beginning, in our company, the installation and management of the systems were dealt with by the functional consultants/consultants of the respective systems. The CRM consultant was responsible for the SAP CRM system, the SRM consultant for the SAP SRM, etc.
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.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
By defining a target group within a company, the SAP basis decides for whom the services and IT products should be delivered.
This must be evaluated and decided jointly.
