Engineers make cyber networks safer by protecting networks as well as devices and services from malicious attacks. They are trained to know the infrastructure behind systems to protect the secure network and where the network is most vulnerable to attack and monitor it for attacks. They provide integrity to the business that hires them to provide cyber-security for their company that their systems are protected. They also launch solutions that keep the information systems secure against cyberattacks. They also consistently monitor as well as test networks and systems to make sure the function properly and stay updated. The engineers also design and build new network infrastructure for businesses. In doing everything that they do engineers protect not only information but also provide the business with protection from loss that could result in the business closing for good. Engineers can also provide businesses with comprehensive protection, which allows for employees to surf the web without the risk from potential threats which is one of the most common ways an attack can happen to a business. An engineer should be able to figure out where an attack may take place and monitor that vulnerability more frequently than more secure parts of the network. Engineers also allow for technology to grow safely by keeping up with knowledge of changing and evolving technologies that come along with upgrading a company’s network. The networks that engineers generally maintain include extranet, local area network (LAN), intranet, and wide area network (WAN). At the end of the day engineers are probably the most important aspect in keeping a network secure over a long period of time. They help to reduced and try to have no incidents of an attack the result in loss for the company or of the company. They maintain the systems that they design and implement for companies that hire them.
