Network Security

1. Trojan Horse

2. Spyware

3. Worm

4. DDoS

5. Phishing

6. Virus

7. Brute Force Attack

8. Phishing

   • Normally an email or text messaging scam where victims are conned into believing that they are being contacted by an authentic organisation (e.g. by their bank) and can give sensitive personal details (such as bank account passwords).

9. Spyware

   • Records the activity on your computer such as your keystrokes, thereby logging your passwords for instance and then sending the data back over the network to the attack instigator. Spyware can also be used to control your webcam and microphone.

10. Trojan Horse

    • ains access to a computer by pretending to be legitimate software. The trojan allows unauthorised backdoor access to a computer without the user being aware.

11. Brute Force Attack

    • When all possible password combinations are systematically tried, with the hope of getting it right.

12. DDoS

    • When a network resource becomes deliberately overloaded (‘flooded’) with unnecessary requests, preventing it from responding normally.

13. Worm

    • Spread like viruses but do not require human intervention. They attach themselves to network tools to spread automatically around a network very quickly.

14. Virus

    • Insert themselves in normal programs. Viruses can replicate themselves and transfer from one computer to another. They are activated by a user often as email attachments and attachment to other files and programs.
