From: EPASAD: ellipsoid decision boundary based Process-Aware Stealthy Attack Detector
We demonstrate an MSA scenario where PASAD framework fails to detect the attack because of the attack’s projection towards the loose side. Subfigure a shows measurements generated by the reactor’s cooling water outlet temperature sensor (XMEAS(21). The red measurements are captured under a micro-stealthy attack (MSA1). Note that all other aspects and subfigures have same definition as Fig. 1
