Firewall is a device that secure the private network from unauthorized access. Model based  tool assistance  facilitate the design task and has contribute to the correctness of the filters. But the model based tool assistance approach is design time only does not manage actions at run time. So we shall propose model on run time auditing architecture to detect the attack while packet filtering in firewall technology. It is usually based on the log-files of the packet-filters.

Control Layer

In this paper an example of a hierarchical context-aware run-time reconfigurable control system is presented. The context-awareness is resulting from using policy-based computing as a technology allowing the control system to replace its decision making logic in run-time in response to changing environment conditions. The proposed solution allows system experts to specify policies (AGILE policies) used in the Supervision Layer for the purpose of making decisions regarding the most appropriate controller configuration and on the other side, they can specify policies (Fuzzy Logic policies) used in the Control Layer in order to generate control signals allowing to achieve specified control goals. Novelty of the proposed solutions lays in combination of two technologies, Open Decision Point technology originating from the Software Engineering domain Policy-based Computing that is originating from the Knowledge Engineering domain in application to non-linear control systems.

Robotic Applications

Autonomous Robots normally perform tasks in unstructured environments, with little or no continuous human guidance. This calls for context-aware, self-adaptive software systems. This paper aims at providing a flexible adaptive middleware platform to seamlessly integrate multiple adaptation logics during the run-time. To support such an approach, a reconfigurable middleware system “ACCADA” was designed to provide compositional adaptation. During the run-time, context knowledge is used to select the most appropriate adaptation modules so as to compose an adaptive system best-matching the current exogenous and endogenous conditions. Together with a structure modeler, this allows robotic applications’ structure to be autonomously (re)-constructed and (re)-configured. This paper applies this model on a Lego NXT robot system. A remote NXT model is designed to wrap and expose native NXT devices into service components that can be managed during the run-time. A dynamic UI is implemented which can be changed and customized according to system conditions. Results show that the framework changes robot adaptation behavior during the run-time.

Context Models

Today’s enterprises need to be agile, to be able to cope with unexpected changes, to increasingly be dynamic, and to continually deal with change. Change affecting business processes may range from ad hoc modification to process evolution. In this chapter we present dimensions of change concentrating on a specific ability of an enterprise to deal with change. To support business in being agile we propose a semantically enriched context model based on well known enterprise architecture. We present a context aware workflow engine basing on the context model and on rules which trigger process adaptations during run time.
