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 and sends the data back over the internet to the attack instigator.

3. Trojan horse

   • Gains access to the computer by pretending to be a real software. It allows unauthorised backdoor access to a computer without the user being aware.

4. Worm

   • Attach themselves to network tools to spread automatically around a network very quickly. Do not require human intervention.

5. Phishing

   • Normally an email or text messaging scam where victims are conned into believing they are being contacted by an authentic organisation.

6. Virus

   • Insert themselves in normal programs. They can replicate themselves and transfer from one computer to another.

7. DDoS

   • When the requests come from many sources so you cant just block a single IP address.
