How is SAP Basis structured?
SU25 Profile generator: upgrade and initial installation
In the result table USERTCODE are the transaction codes of the SAP users. Afterwards you simply have to output the complete list via "Object > Output complete list". Then save the list via "System > List > Save > Local file". The column Account contains the SAP user. This way you can see the used transactions grouped by SAP user.
It is possible to specify a trace level for each rule in the ACL file to monitor each communication channel individually. It can be used with SNC without any further configuration. The use of the file is controlled by the gw/acl_file parameter by simply setting it to the appropriate file name. Use of external programmes If an external programme wants to communicate with your SAP system, it must first register at the gateway. The programmes which this is approved are controlled by the reginfo ACL file. This defines rules that allow or prohibit certain programmes. The syntax of the file allows you to define not only the name of the programme, but also the host on which the programme runs and hosts that can use and exit the programme. The gw/reg_info parameter must be set to use this file. In addition, there is the ACL file secinfo, which allows to configure which users can start an external programme. This defines rules that allow certain usernames from the SAP system to use certain external programmes. In addition, you can also define the hosts on which these programmes will run. For example, it is possible to allow a user to run the programme "BSP" on the host "XYZ", but not on the host "ABC". This file is controlled by the gw/sec_info parameter. Using the gateway as a proxy Since the gateway of your SAP system can also serve as a proxy server, the prxyinfo ACLDatei should also be activated via the gw/prxy_info parameter. Suppose you have 3 SAP systems in your network: SRC, TRG and PRX. If SRC cannot communicate directly with TRG, but both with PRX it would be possible to use the gateway of the PRX system as a proxy server, i.e. to communicate via it. So, in order to prevent this from happening to everyone, this property should be urgently restricted. As with the other ACL files, rules are defined which hosts can communicate with which hosts via the gateway. The syntax of the different ACL files may vary depending on the release level. It is therefore advisable to read them in the appropriate SAP documentation before activating the ACL files. You can also find more support for using ACL files in the SAP Community Wiki.
Update & Upgrade
In practice, it is quite possible that the target specifications defined in the security concept do not match the current actual status. Therefore, especially with regard to SAP security, it must always be checked whether the necessary SAP basic settings also correspond to the minimum level. Although a manual check is possible, it is very time-consuming because the necessary regularizations have to be read, interpreted and technically implemented. The Security Architect - part of the Xiting Authorizations Management Suite (XAMS) software solution developed by Xiting - offers you the possibility to precisely examine the current status of the SAP Basis settings with the help of the integrated check mode, whereby it is also possible to check several systems via RFC, starting from a central system. The scope of the check of system settings and system security includes not only the SAP Basis settings presented here, but also other SAP Basis settings. The scope of the check mode can be extended by self-defined check IDs.
This SAP training covers the introduction/basics of SAP administration. You will learn the basic functions of the SAP system. You will learn the most important administrative tasks, such as user administration and roles, the SAP data transport system, security in the SAP environment, administrative background tasks and system monitoring.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
