Sound up-to-date know-how: With SAP Basis support, you can save time and money on training that would be needed in-house to keep your employees up to date. An SAP expert is always familiar with the latest technologies.
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.

The 5 most common errors in SAP test management In this blog post I would like to discuss the 5 most common errors in SAP test management, which in my experience occur regularly in this area. I hope that with this I can give you some guidance so that you can avoid these mistakes. No test management Quite simple. You have complex SAP software in use or are just introducing a new module tailored to your company, but the test process plays a subordinate role and tests take place only sporadically and unstructured? Then you have already made the first mistake. To ensure high software quality, avoid hidden consequential error costs and consciously plan for a test period instead of the risk of time bottlenecks, a methodical approach should be planned. Too much testing If you have decided to introduce test management, you need to weigh up the resources required for this. A large amount of testing quickly pushes the cost-benefit ratio into the realm of inefficiency, because the time required for testing drives up costs. On the other hand, the test quality should of course be high. Therefore, a structured and comprehensive approach is of high importance. Basically, you should make sure that the costs for the test effort do not exceed the average of the consequential failure costs.
The "Shortcut for SAP Systems" tool is ideal for doing many tasks in the SAP basis more easily and quickly.
In order to ensure the stability of the systems and to reduce the risk through proprietary developments, release and patch management must be implemented.
Since the respective GUI depends entirely on the concrete application, the presentation layer looks very different in practice.
