Among others, we offer the following services:
Within SAP R/3 Enterprise, the SAP Basis Plug-In is a prerequisite for you to use the SAP R/3 Plug-In. SAP Basis Plug-In and SAP R/3 Plug-In must always have the same release level, for example PI 2004.1 and PI Basis 2004.1. If you plan to upgrade SAP R/3 Plug-In within SAP R/3 Enterprise, you must also upgrade SAP Basis Plug-In. As of SAP Basis Plug-In 2005.1, the release levels of the two plug-ins no longer need to correspond. However, the SAP R/3 Plug-In Support Package for PI 2004.1, which contains new interfaces, still requires a specific SAP Basis Plug-In. For example, SAP R/3 Plug-In Support Package 10 for SAP Plug-In 2004.1 requires SAP Basis Plug-In 2005.1.

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.
SAP BASIS - THE SECURE FOUNDATION OF THE SAP SYSTEM
The security of an SAP system requires protection against unauthorised access, e.g. through the secinfo and reginfo files. A cleanly implemented authorisation concept protects against attacks within the SAP system. However, it is also possible to attack your SAP system via the network. Through the RFC Gateway Server, your system communicates with external servers and programmes. One particularly effective way to protect against this are so-called Access Control Lists (ACL). Find out what this is and how you can use it to better protect your SAP system. The SAP Standard offers different approaches for gate protection. All methods combined can provide even greater safety. For example, it is possible to use Access Control Lists (ACL) to monitor exactly which external programmes and which hosts can communicate with the gateway. Another option is to configure the gateway to support Secure Network Communication (SNC). Finally, there are various security parameters for the gateway. This article focuses on the use of ACL files such as secinfo and reginfo files. What is an ACL? Access control lists are files in which permitted or prohibited communication partners can be recorded. For the gateway to use these ACL files, parameters must be set in the default profile of the SAP system and of course the files must be maintained accordingly. With the help of logs and traces, which can be configured for this purpose, a precise investigation can be made in advance of the activation, which connections currently run via the gateway. This allows them to prevent important applications with which your system communicates from being blocked by the ACL files. The rules in the ACL files are read from top to bottom of the gateway to decide whether to allow a communication request. If none of the rules matches the requesting programme, it will be blocked. Network-based ACL The network-based ACL file contains permitted and prohibited subnets or specific clients.

SAP will provide all SAP Notes in the SAP ONE Support Launchpad digitally signed. This is to increase the security when the updates are loaded. If you have unsigned SAP hints, there is a risk that the notice has been changed unnoticed and malicious code will be added to your SAP system when you install the notice. This poses a significant threat to the SAP system, which is why the digitally signed provision of the clues is an important improvement. However, to use digitally signed notes in your system, you will need to take a few steps to prepare them. If you install SAPCAR version 7.2 or later and have a user with the necessary permissions, all you have to do is insert the Note 2408073 into your system and do the manual pre- and post-processing. A digital signature technically ensures that any change can be detected at the notice and can be checked by the system to see if the present note, which is to be inserted into the system, is unchanged. Prerequisites to use digitally signed SAP hints To prepare your SAP system for digitally signed clues, you first have to meet some requirements: Digital signed SAP hints are provided as SAR files. The SAR files are unpacked with SAPCAR and checked for their digital signature. SAPCAR must be available on the Application Server in version 7.20 or higher. Therefore, it is strongly advised to update SAPCAR. If SAPCAR is not at least in version 7.20, the digital signature verification fails and the message cannot be unzipped. Installation of the digitally signed clue is then not possible. The implementing user also needs some permissions to perform the necessary manual pre- and post-processing of the note on the system: Authentication for the transaction SLG1 Read permission for the S_APPL_LOG permission to write and delete data from the application directory Upgrade the SAPCAR version on your system to version 7.20 or higher SAP basis version 700 or higher, for older versions the notice must be inserted manually If you have met these requirements, you can use the implementation of note 24080 Start 73. Implementation SAP Note number 2408073.

With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.

In a central system, the central institution does that.

Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.


A potential attacker now has the ability to read out your database with the password hashes.
