Significant changes have also been brought about by SAP's cloud strategy. For example, the latest products such as SAP HANA and SAP S/4HANA are available entirely as cloud solutions.
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 lockout issues: Call the SM12 transaction and make sure that there are no programmes named RDDIMPDP. For more information, see Note 11677. ADDON_CONFLICTS_? This step checks to see if there are conflicts between objects in the queue and add-ons installed. If there are such conflicts, SPAM will cancel and prompt you to play the appropriate Conflict Resolution Transports (CRTs).
In every company with several SAP systems, there is a person responsible for the complete SAP Basis topics, usually there is even a separate department for this. This person ensures the trouble-free operation of the SAP systems. The person responsible also accompanies maintenance work or upgrades and intervenes in special situations, such as poor performance. Even for companies that hand over the operation of the SAP Basis to an external service provider, there are often still tasks from the environment of user and authorization management at this point.
With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.
The role of the Technical Lead functions as (partial) project leader for topics and projects of particular importance to the SAP basis.
While Bitcoin allows only rudimentary multi-signature functions, Ethereum opens the door to much more complex operations called smart contracts.
