In the wave of intelligent manufacturing and “Industry 4.0”, industrial automation is upgrading from dedicated hardware PLCs to flexible programmable software platforms. As the core control unit of factory automation, PLCs play a fundamental supporting role in achieving the goals of intelligent interconnection and flexible production required by “Industry 4.0”. The performance upgrade of PLCs … Read more
Competitors are becoming increasingly intelligent and efficient, and are also becoming more adept at infiltrating industrial networks. Recent survey data from Booz Allen Hamilton reinforces this fact. The company surveyed 314 companies globally that operate industrial control systems (ICS) and found that 34% experienced more than two data breaches within a year. In 2015, the … Read more
In mid-May, “WannaCry” began to sweep the globe, affecting over 300,000 computers in more than 150 countries and regions within just a few days. The impact on key industries such as energy, electricity, transportation, healthcare, education, and manufacturing was shocking. Half a month has passed, and while the attacks seem to have subsided, the reality … Read more
Industrial Control Systems (ICS) are the core support of modern industrial fields, encompassing various types of control systems, among which the Supervisory Control and Data Acquisition (SCADA) system, Distributed Control System (DCS), Programmable Logic Controller (PLC), and Fieldbus Control System (FCS) are the most critical. These systems are not only widely used in power, water … Read more
On January 7, MITRE released the ATT&CK for ICS knowledge base, which mainly introduces the strategies and techniques used by cyber attackers when targeting industrial control systems (ICS), providing a reference for critical infrastructure and other organizations using industrial control systems to assess network risks. Why ICS? First, what is an industrial control system? It … Read more
