Towards Comprehensively Understanding the Run-time Security of Programmable Logic Controllers: A 3-year Empirical Study. (arXiv:2212.14296v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Programmable Logic Controllers (PLCs) are the core control devices in
Industrial Control Systems (ICSs), which control and monitor the underlying
physical plants such as power grids. PLCs were initially designed to work in a
trusted industrial network, which however can be brittle once deployed in an
Internet-facing (or penetrated) network. Yet, there is a lack of systematic
empirical analysis of the run-time security of modern real-world PLCs. To close
this gap, we present the first large-scale measurement on 23 off-the-shelf …
