The SecServ prototype was originally designed as a security service with a special focus on access control for adaptive process management systems. Over time the scope of SecServ got extended and the system emerged to a technology platform for modeling and executing both imperative and constraint-based workflows.The overall archicture of SecServ is depicted in Fig. 1.

Fig. 1: Architecture of SecServ

- SecServ Modeler is a modeling environment for both imperative and constraint-based workflows.

- SecServ Server allows for the integrated execution of imperative and constraint-based workflows.

- SecServ Client can be used to access the SecServ Server and provides worklists for task execution.
