In this paper, we study the effect of attacks on networked systems and propose a new security index to analyze the impact of such attacks using H2 norms of attacks to target and monitoring outputs. In addition, we pose, and subsequently solve, optimisation problems for selecting inputs or outputs that point to attacks with maximum impact and least detectability. To demonstrate the applicability of the analysis methods proposed in this paper IEEE 9-bus and 50-generator 145- bus systems are considered as test cases.
