Applying separation of concerns approaches into business process context generally results in several initiatives oriented to automatic generation of aspect code, generation of specific code according to the kind of concern (code for mapping roles and permissions derived from RBAC model for example), or proposition of new mechanisms as dedicated aspectual languages. Most of these initiatives only consider functional behaviours of business process, omitting special behaviours derived from quality attributes such as security, which can be modelled as concerns that must be supported in the business process. In this paper we propose the integration of cross-cuttings standardized control access policies (based on RBAC model and Oasis XACML) into legacy business processes, using a separation of concerns approach.
