Network security basics for building better corporate systems

Grasping network security basics is an essential first step. This guide also helps you understand the current threats as well as the tech developments like SDN that will make your network more secure.

Introduction

It's tempting to focus on the latest high-tech security tool but most infosec pros acknowledge that all those digital, cloud-based bells and whistles won't protect a network if the network security basics aren't in place. In the segments to this guide we cover basic first steps, touch on fundamentals like the importance of visibility even in the virtual age, while also peering into the future of network security. Readers of this guide should come away with a deeper understanding of network security basics and an overall "lay of the land" which it comes to securing the network.
