SAP, one of the most preferred corporate logistics information systems today, is widely preferred by institutions to manage critical processes such as finance, human resources, maintenance and production. SAP's technical and system complexity poses serious risks, especially in terms of cybersecurity. In this chapter, a security hardening model has been created to ensure SAP's cybersecurity. In this context, critical assets were first identified and risk assessments were made on these assets. After the risk assessment, threats related to risk assets were analyzed using the MITRE ATT&CK framework and preventive activities to reduce threats were determined using the MITRE ATT&CK framework.
