Two years ago, the authors assessed 20 mobile applications that worked with ICS software and hardware. At that time, mobile technologies were widespread, but IoT mania was only beginning. In that paper, the authors stated, “convenience often wins over security. Nowadays, you can monitor (or even control!) your ICS from a brand-new Android [device].”
Today, the idea of putting logging, monitoring, and even supervisory/control functions in the cloud is not so farfetched. The purpose of this paper is to discuss how the landscape has evolved over the past two years and assess the security posture of SCADA systems and mobile applications in this new IoT era.
