Over the past three weeks, we've explored the many potential threats to our digital lives. We've also taken a closer look at ways of keeping attackers from impersonating you online or infecting your devices with malware. Now we're going to delve a little deeper into the technology that underpins information security, focusing first on how to protect the internet itself and the network security problems that can affect it.
By the end of the week you'll be aware of some of the networking standards that allow different devices to connect to the internet and exchange information. You'll also be able to explain how data is transmitted across networks. And you'll understand the difference between the internet and the world wide web.
