This Journal is about how How engineers make cyber networks safer. The process of making cyber networks safer is complicated. This is because if it is a large network a large amount of people use it every day. The way these engineers makes these networks safer is complicated but are very advantages to a cyber network. One way cyber engineers make a network safer is to restrict access. This might sound counter intuitive but it is the best way to ensure that there are people with malicious intent on the network. This can be done through a few means, the first mean is by the use of firewalls. By controlling the traffic that comes into the network from outside the network this limits the number of people who could launch an attack on the network, or people on the network. The next thing a cyber engineer can do to ensure that their is strict access to a network is to use username and passwords for the network. This means that to get onto the network a person will need the credentials of a person who works for the company in question. This will also help to ensure that no outside threat gets into the network easily. That is the real job of an engineer, there will almost always be a way to get around security but its whether it would be worth it for the attacker to try and get around. If an attack would take years to break with minimal gain the hackers will look for an easier target.
