Blog Post 7 - Understanding Network Security

I chose to write about network security, what it means and how to implement features to protect a network. Throughout our course and text, we’ve discussed the concept of information technology.

Whether it’s a personal home network, connecting a couple of computers to a printer, or something larger such as a major organization’s network of computers, or even bigger, the World Wide Web, all networks require some form of security. According to Cisco, “network security combines multiple layers of defense at the edge and in the network” (What is network security, 2019a). Our text discussed the different types of attacks computers can face, such as DDOS attacks, malware attacks, and trojans (Vahid & Lysecky, 2017). These types of attacks, as well as others, can go undiagnosed or prevented based on the level of security in place for each network.
