The project in five facts.
Challenge, approach and results.
The diploma thesis addresses business process modelling using the BPMN 2.0 standard with particular emphasis on a comparative analysis of the Camunda Modeler and Signavio Process Manager tools and on incorporating security aspects into the process modelling phase. The interoperability of both tools was also verified, and it was found that the exchange of BPMN models is possible and reliable as long as the models comply with the BPMN 2.0 standard. In the practical part, an extension of the BPMN modeller was developed using the bpmn.io library, which enables the addition of security components to BPMN diagrams.
Solution and Method
The diploma thesis addresses business process modelling using the BPMN 2.0 standard with particular emphasis on a comparative analysis of the Camunda Modeler and Signavio Process Manager tools and on incorporating security aspects into the process modelling phase. The theoretical part presents the basic concepts of BPMN, XML notation of BPMN models, an overview of existing modelling tools, and legislative and security frameworks. Particular emphasis is placed on the role of business processes in managing cyber risks and the importance of security-aware modelling.
The central part of the work presents a comparative analysis of the Camunda Modeler and Signavio Process Manager tools. The analysis showed that Camunda Modeler is more user-friendly for process modelling due to its simple, clear and minimalist user interface, especially when the processes are intended for automation and direct execution. Signavio Process Manager, on the other hand, stands out in the areas of collaboration, documentation and process analytics, but due to the greater complexity of the user interface, it requires more time to use.
Results
The interoperability of both tools was also verified, and it was found that the exchange of BPMN models is possible and reliable as long as the models comply with the BPMN 2.0 standard. In the practical part, an extension of the BPMN modeller was developed using the bpmn.io library, which enables the addition of security components to BPMN diagrams. The extension enables visual marking of security-critical user tasks and the storage of additional security attributes in the BPMN XML notation.
This incorporates security aspects into the process design phase, which contributes to better understanding, early risk identification and greater process transparency. The results of the work confirm that BPMN can be effectively enhanced with security components and that Camunda Modeler represents a suitable basis for such extensions. The work contributes to better integration of process modelling and cyber security and opens up possibilities for further development and integration of security mechanisms in BPMN environments.
