Lesson Details
Key learning points
- Cyber attacks can target individuals, organisations and countries.
- The effects of cyber attacks can be financial and disruptive.
- The WannaCry Ransomware Attack in 2017 affected more than 200 000 computers in 150 countries.
- The infection and spread of WannaCry may have been stopped by using a combination of security measures.
Common misconception
As long as you use all security measures, a computer system connected to a network can be totally safe from cyber attack.
No computer system on a network can be completely safe, even with all security measures. Cybercriminals can find new ways to attack, so security only reduces the risk and doesn't completely eliminate it.
Keywords
