Protecting networks from security threats
Lesson details
Learning outcome
I can compare threats to the security of a computer system and suggest protective actions to take.
Key learning points
- Threats to security can be compared by likelihood and impact.
- Protective measures are used to make it difficult for attackers to achieve their goals.
- Combinations of protective measures make computer systems more secure.
- Training users of a network about risks can help keep a network secure.
Keywords
Cybersecurity - the protection of computer systems from threats
Firewall - a system that filters network traffic to protect against unauthorised flows of data in or out of the network
Common misconception
Using security measures will stop every cyber attack.
Security measures reduce the risk of cyber attacks but cannot stop all of them. New threats and advanced techniques can sometimes bypass even the best defenses.
Teacher tip
Analogies are a good way of helping pupils understand the way that technology operates. For example, a firewall could be likened to leaving doors of a house open or locked.
