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.
There is no way around containers, and even SAP will soon have to reorient itself here and allow the NetWeaver stack to be run in containers. There are many indications that Kubernetes will win the battle for supremacy among container management tools. SAP has also already invested in Gardener and is also intensifying its partnerships with IBM and Red Hat Openshift.
Objectives of the training SAP HANA - Installation and Administration:
The presentation layer is used to visualize the applications and data for the user. The presentation is done with the help of a graphical user interface (GUI). Furthermore, the presentation view consists of several modules, which are also summarized as SAP GUI. SAP Fiori is the presentation layer of the next generation and is therefore particularly user-friendly.
First you have to create an area menu in the area menu maintenance with the transaction code SE43 or SE43N. Then add the created menu to the SAP standard menu S000.
"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.
Load Support Package Usage Before you can insert Support Packages, you must first load the appropriate Support Packages.
In essence, it consists of a database management system (DBMS for short) and the data itself.
