Engineers play an important role in securing cyber networks. Engineers play an important role in the creation of networks. In creating new networks engineers can also aid in patching vulnerabilities in networks. This plays a vital role in both discovering holes in the network defenses but also patches and strengthens the networks security. Engineers also aid in the creation of the physical security of a network. In designing building to provide the most secure physical security to vulnerable network hardware is another way engineers make networks more secure. Updating networks is another way engineers make networks safer. Planning for growth and implementing updates is a vital part of network security. As a business grows and the demand of networks increase engineers play a vital role in ensuring networks stay functional for years to come.
