MARKETING & SELF-UNDERSTANDING
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.
An understandable and comprehensible strategy enables the SAP basis to derive it as easily as possible to practice and to the resulting requirements and activities. The main task of the SAP basis is to support new business models by implementing the strategy and to show how much technical and financial effort and benefit is generated. It is also the task of the SAP basis to identify the skills and resources necessary for them and to ensure their existence at an early stage.
SAP S/4HANA
In more complex system environments, thousands, if not tens of thousands, of SAP jobs can run per day. Their interdependencies create a high level of complexity. If administrators or admin teams want to maintain an overview, they have to rely on meaningful monitoring. It must be clear at all times which jobs are running and which are not, in order to ensure proper SAP operation. Ideally, one is informed of critical errors by e-mail or SMS. The trend towards internationalization, outsourcing and mixed operation with on-premise and on-demand systems means that SAP landscapes are often widely distributed. This makes monitoring more difficult and, at the same time, clarity must be maintained. Integrating SAP job management and job requests into a central system, such as SAP Solution Manager, therefore makes sense and is useful for supplementing IT service processes in a meaningful way and accelerating process flows.
Examples of names are: SAP Cross-Application, SAP Innovation & Technology, SAP Services & Innovation, SAP Operations & Innovation or SAP Service Provider & Business Innovator. DESCRIPTION OF OWN PERFORMANCE AND SERVICE PORTFOLIO In order to be consulted by upstream or downstream entities, it is necessary to provide a detailed and understandable description of your service portfolio. This means that it can be explicitly stated in which cases the SAP basis needs to be contacted and involved in order to make the necessary decisions and not jeopardise a project or company success. In addition to the range of tasks covered by the SAP basis, it is also necessary to specify for which tasks and topics the SAP basis is not responsible. This recommendation is to be considered as universal and applies to all IT departments in order to clearly distinguish them and document the performance of their own IT organisation. INTERNAL MARKETING DESIGN AND ESTABLISH Building on the recommendation [A3], it is recommended to design and establish an internal marketing. The aim is to provide a transparent picture of the activities carried out in terms of the company's success and which are not visible to everyone.
