Typical ICS Security Incidents As ICSs are increasingly informatized and open, more and more attacks are hitting ICSs, doing an increasing harm. ICS-targeted attacks use the IT network as a springboard to affect the operating of OT systems. Currently, attacks against ICSs are carried out to achieve three purposes: disrupting the normal operating of ICSs, […]
Technical Trend of ICS Information Security 1.3.1 General Introduction As the application of IT technologies in industrial fields is expanding in breadth and depth, ICSs are facing an increasing number of security risks. ICSs’ original security protection systems which feature border separation and protection tend to be associated and integrated with business. With the emergence […]
Development of ICS Information Security Since the Stuxnet virus explosion, countries all over the world have taken ICS security issues to a new height by actively working out and introducing related policies, standards, technologies, and solutions. A look into ICS security developments around the world reveals that the USA is the first to research and […]
Distribution of IoT-based Family Samples We analyzed IoT-based malicious family samples captured by NSFOCUS threat hunting systems (see Figure 7-1), those captured by NSFOCUS Threat Intelligence (NTI) and those captured by VirusTotal (see Figure 7-2). The two figures, though presenting different data sources, both indicate that Gafgyt and Mirai take the first two places on […]
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 January 12, 2020.
1.2 Development of ICS Information Security As industrial informatization advances at a rapid pace and the industrial Internet, industrial clouds, and other new technologies spring up, information and network technologies and IoT technologies have found wide application in smart grid systems, intelligent transportation systems, and industrial production systems. For the sake of inter-system collaboration and […]
Development of ICS Security 1.1 Development of Industrial Intelligence The following figure shows the development history of industrial control systems (ICSs). The history of ICSs can date back to the 18th century when James Watt improved the steam engine by adding a throttling controller, i.e., a centrifugal governor. The centrifugal governor works like this: It […]
With the advancement of IT-based transformation and the rapid development of IT, various network technologies have seen more extensive and profound applications, along with which come a multitude of cyber security issues. Come to find out what information security issues you should beware of in the workplace.
6.3 Worm In the 2018 H1 Cybersecurity Insights , we pointed out that most worm viruses were discovered more than five years ago. This indicates how capable these viruses are of propagating and evolving and how difficult it is to remove them completely from the network. According to data throughout the year, this was still […]
