Basis comprises a number of middleware programs and tools from SAP. Basis is responsible for the smooth operation of the SAP Basis system and thus for R/3 and SAP ERP, for example. SAP thus provides the underlying basis (hence the name) that enables various SAP applications to be interoperable and portable across operating systems and databases.
The application layer is the core of an R/3 SAP Basis system. This layer communicates in both directions, to the presentation layer and to the database layer. The application programs on the application servers request the required data from the database layer, process it, prepare it for the user and pass it on to the presentation layer. Data that the user enters in the SAP GUI is passed on to the database via the application servers.

Administrators often need to replicate part or all of a database, for example, to create a system backup or test an upgrade before putting it into production. In the past, this was surprisingly difficult to do with most databases. With HANA, replication works instantly and offers richer features and better control than previous databases.
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.
