There many ways that engineers make cyber networks safer, this can summed up into the term “Industry 4..0”  this is defined as the rapid transformation of the virtual world of information and the physical world of machines, and the internet. The benefits of this include, Improved machine intelligence, more automated processes and self-monitoring in real time and the growth of efficient and scalable production.  With upcoming new technology this means there leaves room for vulnerability to things such as adware, phishing and malware. Security engineer analyzes networks and makes sure everything is running right and secure and tries exploit possible security issues that may arise in the future. Cyber security engineers perform assessments and penetration testing; provide development and implementation of secure network solutions by architecting and engineering trusted systems into secure systems, and manage audit/intrusion and security technology systems. Other ways Engineers make cyber networks safer is they perform assessments and penetration testing: provide development and implementation and offer solutions and troubleshooting to an organization.  Industrial cyber system applications can found in agriculture applications, water and wastewater processing facilities, as well as an in transportation. Engineers have made cyber networks safer in the way of SCADA (Site Control and Data Acquisition) and DCS (Distributed Control Systems). The general system layout of a SCADA system is 1) Sensors and actuators 2) RTUs/PLCs 3) Communication 4) Master Terminal Units. Sensors and actuators have helped in the way to alert security system with alarms and made it possible to detect danger in networks. PLCs have is an industrial digital computer that replaced traditional relays. These things effect assembly lines and they are noted for ease of programming making it easier for everything else. RTUs is an electronic device with intelligent microprocessor, they accomplish data logging and alarm handling. With the engineers making these products they evidently giving cyber networks the tools to make things safer.
