​Internet security

​​The Internet is a global network of millions of computing devices that are connected to each other. There are mainly two types of computer in a network:
1. Server: Computers that provide information.
2. Client: Computers that request information.  

A client depends on the server to provide and manage information. The client side of a web application is a web browser from which the information is requested. The web server provides the information.

This ​KS3 Computer Science module introduces ​internet security to your students, explaining:

  • ​​Client-server model
  • World Wide Web
  • Misleading websites
  • Threats to computers such as malware, phishing and brute-force attack
  • How to check the correctness of information on the Internet
