System Introduction The computer monitoring system of the hydropower plant adopts a hierarchical distributed open system structure totally controlled by the computer, which consists of the main control layer of functions and the local control unit (LCU) layer of objects. The main control layer consists of the operator station, data server station, external communication station, […]
Wind Power System Introduction Based on computers, communication devices, and test control units, the wind power monitoring system provides a basic platform for real-time data collection, switch status monitoring, and remote control of wind power plants. It can work with detection and controls devices to form an arbitrarily complex monitoring system. It plays a vital […]
ICS Security Solutions for Typical Industrial Scenarios System Introduction Based on computers, communication devices, and test control units, the electric power monitoring system provides a basic platform for real-time data collection, switch status monitoring, and remote control of thermal power plants. It can work with detection and controls devices to form an arbitrarily complex monitoring […]
Top 10 countries in attack counts: The above diagram shows the top 10 regions with the most malicious IP addresses from the NSFOCUS IP Reputation databases at February 2, 2020.
Policies for Building the Defense-in-Depth System for Industrial Control Networks For the sake of ICS security protection, we can build a defense-in-depth system by implementing the following policies:
ICS Information Security Assurance Framework ICS Security Assurance Principles In response to related compliance requirements put forward by the industry and the country, the ICS information security assurance framework will be developed to combine both technology and management, taking full account of the enterprise’s business requirements and ICS operating characteristics. By switching ICS protection from […]
2.4 ICS Security Trend All in all, with IT and OT converging at a rapid pace, ICSs will be exposed to more threats that are evolving faster and faster. The threat evolution is reflected in the following aspects:
2.3.2 ICS Vulnerability Trend As industrial control has been delving deeper in recent years, more and more ICS vulnerabilities are discovered by researchers. As vulnerabilities publicly available are only a small portion of those hidden in ICSs, the possibility of ICS vulnerabilities being stashed as potential cyber weapons cannot be ruled out. The following sections […]
2.3 Vulnerabilities in ICS Assets Most ICS security mechanisms are short of authentication, encryption, and audits, and therefore such ICS assets are rather vulnerable. When connecting to the Internet, ICSs are susceptible to external probes or identification via special fields included in information returned through public or private communication protocols, web services, telnet, and FTP. […]
