Legacy power grids were typically designed with reliability as the main goal. With the transition to the smart grid, security concerns have begun to arise; due to the computational and communication capabilities of the integrated elements, smart grid technologies are becoming vulnerable to cyber-attacks. This chapter aims to enumerate existing threat vectors in the various layers of smart-grid architecture and provide insights of how security techniques should be implemented in order to ensure smart grid resiliency.
