Network sercuity threats

Network sercuity threats

1. Trojan horse

   • 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.

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. Worm

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

4. 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).

5. 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.

6. DDoS

   • when the requests come from many sources so you cannot just block a single IP address.

7. Brute force

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