What is network security?

Network security. It sounds so official, doesnt it? But really, at its heart, its just about protecting your digital stuff (and the digital stuff of others) from bad guys on the internet (or even within your own internal network). Think of it like this: you lock your house to keep burglars out, right? Network security is doing the same thing, but for your computers, phones, servers, and anything else connected to a network.
