Skip to 0 minutes and 12 secondsWelcome to our course. I'm Steve Riddle. And I'll be guiding you through the next three weeks. This course has been developed by a team of colleagues here in our leading security research group in the School of Computing Science at Newcastle University. Over the next three weeks, we'll be looking at some of the latest research in cybersecurity and looking at some practical advice in online privacy, payment safety, and security at home. We'll see that cybersecurity really comes down

Skip to 0 minutes and 40 secondsto a trade-off between three things: privacy, usability, and security. When making online payments, of course, we want our money to be secure. But we also want to be able to get at it easily. So there's a trade-off. To control access to our home, we might use some biometric authentication system, where there's a risk in giving so much information about ourselves for security that we end up compromising our privacy. And as we'll see this week, controlling the amount of data that's held about us online can be done. But controlling privacy can be at the expense of usability. This week, Dr.

So how can you find out what information you do share online? How can you control it? And what are the effects on usability from doing so?

Welcome to the course

Over the next three weeks we are going to explore how the internet is changing how you think about security.

We will do this by focussing on a topic per week, each one designed by experts in cyber security research here at Newcastle University:

  • Week 1: We explore personal privacy online.
  • Week 2: We look at online payment safety.
  • Week 3: We examine security in the home of the (not too distant) future.

A three legged stool - privacy, usability and security

As we’ll see, each of these topics involves a trade-off between three goals: privacy, usability and security. Is it possible to satisfy all three, or do we always have to compromise on at least one of these goals? At the end of the course, you’ll understand the background to this trade-off more clearly and be in a better position to make informed choices.
