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. DDoS

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

3. Virus

   • 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.

4. Phishing

   • Normally an email or text messaging scam where victims are conned into believing that they are being contacted by an authentic organisation and can give sensitive personal details.

5. Worm

6. Trojan Horse

   • The trojan allows unauthorised backdoor access to a computer without the user being aware.

7. 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.
