SAP Decrypt password in less than 24 hours
You would like to know more about what is happening on your SAP systems - then I recommend that you take a closer look at the Solution Manager Usage Procedure Logging (UPL) functionality. What code is often executed? Which database tables are accessed regularly? What unused developments exist? - The UPL provides answers to these questions. You can implement the functionality into your existing SAP landscape without additional licence costs and with moderate effort. What information does the UPL provide? Usage Procedure Logging is used to log and record user behaviour data roughly comparable to the ST03N workload statistics. UPL is able to record the call and execution of the following ABAP objects: Reports Functional Blocks Classes Methods Subroutines SQL Calls In addition, UPL is able to detect dynamic programme calls and generate transparency about the modifications used. All usage data is recorded in detail and automated and, if desired, made available centrally in the SAP Solution Manager. Benefits 1) Hardly measurable Performance Impact 2) Central collection of data of all systems in the SAP Solution Manager's BW 3) No complex setup 4) Once activated, the collector and extractor jobs run regularly and without further manual activities Possible usage scenario If you have Solution Manager 7.2 in use, you can use UPL within the framework of "Custom Code Lifecycle Management" (in German: management of customer developments). After one activation of the BW content and some standard jobs, you select one or more systems for which you want to activate UPL. If you already have the SP05 installed, there is a separate "Guided Procedure" for configuring the UPL in SOLMAN_SETUP.

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 are the following reasons that may lead to the termination of this step: CANNOT_SKIP_ATTRIBUTE_RECORD: The attributes cannot be read in the OCS file. The file probably cannot be opened for reading because it has been deleted in the meantime, or the permissions at the operating system level are insufficient. CANNOT_DETERMINE_EPS_PARCEL: The OCS file does not exist in the EPS inbox; presumably it was deleted.

Within this step, a pricing strategy is chosen. The strategy chosen must be based on the value for money. The selection shall also be justified. The price of the service will continue to be determined, as will formal decisions on clearing models and discounts. This step is less important for the SAP basis. While it is necessary to set a price for the IT products to be defined in terms of appreciation and offsetting, it does not require an elaborate pricing system. STEP 8: MARKET COMMUNICATION The step of market communication describes the way in which the respective service is advertised and how it is to be communicated with customers in this regard. It's about the communication tools that are planned, which describe the place of communication, the communication tools that describe what to advertise, and the content. These are usually derived from the target group to be applied for. For the SAP basis, the content is an essential feature of the market communication. That is, depending on the target group, information must be created and communicated. STEP 9: INTERNAL COMMUNICATION Internal communication describes how the above-mentioned aspects can also be successfully communicated internally, i.e. in the direction of one's employees.

"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.

For example, SAP administration using WebAS with ABAP and Java, system configuration and system updates, applying patches and corrections, and updating users and authorizations.

The freeware Scribble Papers puts an end to the confusing paper chaos. The tool is also suitable for storing, structuring and quickly finding text documents and text snippets of all kinds in addition to notes.

Therefore, call "Change Permissions Data".
