Over the past few weeks, you’ve learned about technologies that can help improve the security of your digital information. You now have an understanding of how cryptography helps keep information private and prevents information from being modified and how to protect networks from attack.

But, as Cory explains, information cannot be protected by technology alone and it is important to have a good awareness of what kind of things can go wrong when an attack on your information has been successful.

This week will help you to recognise the signs of an attack, to know how and where to report the problem, and to consider what you can do to recover from the security breach and stop it happening again.
