The ICS Cyber Kill Chain The ICS Cyber Kill Chain is a report written by Michael J. Assante and Robert M. Lee of the SANS Institute, published in 2015. This report describes the specific processes attackers use to target ICS and abstracts these processes into the ICS Cyber Kill Chain. The report outlines two phases … Read more
1. Classification of Industrial Robots 1. According to the form of operating coordinates, they can be divided into: (1) Cartesian Industrial Robots The motion part consists of three mutually perpendicular linear movements (i.e., PPP), and its working space shape is rectangular. The movement distance in each axis can be read directly on each coordinate axis, … Read more
1. Functions to be Achieved by the Industrial Robot Control System The robot control system is an important component of the robot, used to control the manipulator to complete specific work tasks. Its basic functions are as follows: 1. Memory Function: Stores job sequences, motion paths, motion modes, motion speeds, and information related to production … Read more
1. Industrial Control Security Vulnerabilities Are a Type of Cybersecurity Vulnerability Currently, there is no exact definition of industrial control security vulnerabilities internationally or domestically, but there are relatively mature research results regarding the definition of cybersecurity vulnerabilities. For example, China’s national standard “Information Security Technology – Network Security Vulnerability Identification and Description Specification” (GB/T … Read more

Industrial robots consist of three basic components: the main body, the drive system, and the control system. The main body includes the base and the actuators, which consist of the arm, wrist, and hand; some robots also have locomotion mechanisms. Most industrial robots have 3 to 6 degrees of freedom, with the wrist typically having … Read more
