Abstract:
Any cyber-physical system, including critical infrastructure such as a smart grid, is very likely being controlled by an Industrial Control System (ICS). However, ICSs have long been neglected in terms of security mechanisms. This work presents an overview of the current situation by conducting a literature review, focusing on attack vectors against Programmable Logic Controllers (PLC). Due to proprietary protocols and operating systems, it will present attacks against four major vendors: Siemens, Allen Bradley, Schneider, and Beckhoff.
