Network Security Threats

Network Security Threats

1. Brute force attack

   • Gaining unauthorised access to a network by using a computer program to try all possible password combinations until the correct password is found.

2. 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.

3. Trojan

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

4. Worms

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

5. Adware

   • Adware includes banners and popups that are automatically onto a computer. Whilst this does not cause any damage, adware is undesirable and can slow down the performance of a computer.
