Our SAP Basis experts take care of the operation of your systems every day. They ensure that your SAP systems run smoothly and keep performance at its maximum.

The basic operation of SAP Basis includes the operational readiness of the SAP system, management of system changeability, configuration and administration of system profiles, analysis of system failures, operation and monitoring of technical interfaces, scheduling and monitoring of SAP standard jobs, and much more. The optional services as an extension include activities whose execution and frequency depends on the existing system environment and which can be optionally booked (client copies, execution of client transports and homogeneous/heterogeneous system copies, etc.). These include performing release upgrades, installing enhancement packages, adapting new printer types, device drivers or character sets, and much more.
Overview of used transactions
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.

Whenever you find a red traffic light on the Roles tab in the user master in SU01 - or a yellow traffic light on the Users tab in PFCG, you can usually solve the problem with a simple user synchronization. The fact that such a user adjustment is necessary can have several reasons. Among others: after a role transport to / when assigning users to roles via PFCG after restricting the validity of roles to users when roles are assigned indirectly via organizational management. Users usually notice the problem of a user comparison that has not been carried out quite quickly: Authorizations are missing, although at first glance they are available in the assigned authorization roles. This is because a user is assigned the correct authorization role - but the profile associated with the role is not up to date.
