The appropriate SAP Basis team provides support for 24/7 systems. One of the biggest advantages is, the team is familiar with the company infrastructure. They work with it on a daily basis and can provide quick solutions to concrete problems.
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.

Companies face a major challenge. The world is not going digital, but it is already. The age of digitisation and the related technological changes, as well as the demands of customers, bring new opportunities and new challenges for companies. In addition, the product strategy is changing, including that of SAP. In order to achieve the associated goals of the company and to implement them as effectively and efficiently as possible, the SAP basis must contribute to the design of an IT roadmap and to the design of the digitisation and also cloud strategy. A detailed review of the IT Roadmap recommendation is carried out within the master thesis in chapter 7.9.
SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page: www.sap-corner.de.
The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
User name without restrictions - critical? Depending on the release of the SAP_BASIS component in your system, invisible special characters may end up in the user name. This is especially critical if only spaces or alternate spaces are used for the user name when creating a new user. In Unicode systems, "alternative" spaces, so-called "wide spaces", can be used in addition to the normal space character (hexadecimal value 20). For example, the key combination "ALT+0160" can be used to insert non-breaking spaces. If a user is now created whose user name consists exclusively of such alternative spaces, this can be confusing. This is because entries for this user ID do appear in change documents, but the impression is created that the entry was created by a non-existent / deleted user. This circumstance can lead to confusion. In addition, certain special characters in the user name can also lead to errors, for example in the Change and Transport System (CTS). This is because the user name is also used in the CTS-ORG to create a file with the same name in the transport directory. Furthermore, there are letters/characters that look identical in different alphabets, but have a different hexadecimal value in the character set. This means that confusion in user names cannot be completely ruled out. Seemingly identical user names then stand for different users.
"Shortcut for SAP Systems" is a PC application that simplifies or even facilitates many activities in the SAP basis.
For internal purposes, the SAP administrator also prepares documentation and uses it to search for errors, the cause of which he or she tries to combat.
There is enough space in the transport directory (UNIX: /usr/sap/trans).
