Networked embedded and control systems are largely used in factory automation for production and logistics tasks. In this application domain, security has become a prominent issue due to the critical consequences a cyber attack may have in terms of safety and financial losses. Unfortunately security solutions compete against control applications for the often scarce resources of embedded platforms. In this paper, we show how security can be dealt with as one of different Quality of Service dimensions and traded for control performance in an adaptive QoS management scheme. The system is able to respond to increased resource requirements or to changes in the risk level by reconfiguring the application modes and the security modes. We offer an explanatory case study to show how this idea is implemented.

Abstract
Networked embedded and control systems are largely used in factory automation for production and logistics tasks. In this application domain, security has become a prominent issue due to the critical consequences a cyber attack may have in terms of safety and financial losses. Unfortunately security solutions compete against control applications for the often scarce resources of embedded platforms. In this paper, we show how security can be dealt with as one of different Quality of Service dimensions and traded for control performance in an adaptive QoS management scheme. The system is able to respond to increased resource requirements or to changes in the risk level by reconfiguring the application modes and the security modes. We offer an explanatory case study to show how this idea is implemented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
