According to an article about system security that was published by NIST, “systems engineering provides the foundation for a disciplined and structured approach to engineering trustworthy secure systems”. This means that cyber networks would be safer when it is done by qualified system engineers. “Trustworthy”, in this instance, would also mean better security, more reliability, better performance, and dependability. The job of a system engineer has many disciplines. Some of them include “developing security views and viewpoints of the system architecture and design”, “identify and assess vulnerabilities and susceptibility to life cycle disruptions, hazards, and threats”, and “provide security considerations to inform systems engineering efforts with the objective to reduce errors, flaws, and weakness that may constitute security vulnerability” (Ross et al.). They basically try their best to create and maintain systems according to the requirements set by the stakeholder. This includes both the security objectives and user interface aspects. Cyber engineers also have to constantly analyze their network, looking for any vulnerabilities cyber attackers can take advantage of. To get rid of any risk, they have to continuously update their networks on a regular basis. This patches any bugs and weaknesses that have been identified, which ensures the safety of anyone that accesses the network. Cyber engineers have to work as a team to outline what they can do to improve their network and create contingency plans that would stop future cyber attacks from happening. Overall, the job of a cyber engineer makes cyber networks safer by constantly updating the security of the network, monitoring it for any suspicious activity, working together to track down cyber threats, and generally reducing the amount seen. Without them, the safety of a cyber network would be weakened and the chances for a cyber attack or data breach to happen would be high.
