Abstract: Service Oriented Architecture - It enables the automation of business processes while being completely flexible in responding to company-specific changes. However, companies must adapt their existing security mechanisms and open them up for business partners. This makes it possible to represent seamless and automated business processes, thereby leveraging the advantages of global markets through the new architectural concept. This presents both opportunities and risks. Companies must become aware of these dangers and assess them; only then can appropriate measures be taken to reduce the risk.
