Introduction to Cyber

Learn what cybersecurity protects and who it protects it from. You meet the threat actors behind cyberattacks, find out what malware, viruses and exploits are and how they work, and see how organisations use layered defences, patching and incident response to stay safe. A starting point for anyone new to cybersecurity.
