Security automation is the use of technology that performs tasks with a reduced human assistance in order to integrate security processes, applications, and infrastructure.
The ISA/IEC 62443 series of standards, developed by the ISA99 committee and adopted by the International Electrotechnical Commission (IEC), provides a flexible framework to address and mitigate current and future security vulnerabilities in industrial automation and control systems (IACSs).
All IEC 62443 standards and technical reports are organized into four general categories called General, Policies and Procedures, System, and Component.
Industry 4.0 refers to a new phase in the Industrial Revolution that focuses heavily on interconnectivity, automation, machine learning, and real-time data. Industry 4.0, encompasses IIoT and smart manufacturing, physical production, and operations with smart digital technology, machine learning, and big data to create a more holistic and better-connected ecosystem for companies that focus on manufacturing and supply chain management.
The International Electrotechnical Commission (IEC) has officially designated the IEC/ISA 62443 series of standards as “horizontal,” meaning that they are proven to be applicable to a wide range of different industries.
Almost all industrial businesses are engaged in some form of cyber security. However, the issue of where to prioritize first to increase the security of OT systems comes up frequently. Options often include endpoint protection, network anomaly detection, asset visibility and inventory for improved vulnerability management, and network protection such as segmentation and separation.
Although OT professionals or manufacturers frequently claim otherwise, the truth is that these systems are actually unique. They react slowly to both change and conventional IT security scanning. They have extensive integration. Due to their vast lifecycles, they do run a lot of legacy operating systems. They contain a lot of embedded systems, which are difficult to administer or scan in the same manner as a Windows computer or cloud server. Additionally, responding to a false security alarm has a terrible operational risk. With the proper OT security toolbox, they can be handled. Many of the same controls, such as the CIS Top 20 or NIST CSF, can be used to achieve consistency between IT and OT.
