Network Security Threats

Network Security Threats

1. Virus

   • A computer virus is a malicious software that can spread from computers by using files or documents
     • To prevent computer viruses, you must change your password often and make sure that they are strong. Use a variety of characters such as ! and numbers

2. Phishing

   • Phishing is a type of virus that posed as a trusted business to make the user share their details such as: credit card details, bank account numbers, login credentials and other sensitive data.
     • To prevent phishing scams, you should add or enable your anti-spam filters. This will block emails from being sent to you most of the time
     • To find out if something is phishing email, you need to check grammar, the real website and if you still feel suspicious, check with the real company. Find their email or phone number on their website

3. Spyware

   • Spyware records activity on the user’s computer such as keystrokes to get information such as your passwords. They can also be used to control their webcam and microphone.
     • To prevent spyware use a trusted antivirus software with anti-spyware features. You should also try to stay on secured browsers

4. Trojan Horse

   • Trojan Horse is a malicious programme that causes users to download it when they are unaware that it is dangerous. They hide the attackers true motive by disguising itself as something friendly.

5. DDoS Attack

   • A DDos Attack is a malicious attempt to disrupt the normal traffic of a targeted server or website. The server will be more likely to crash due to multiple computers to attack
     • To prevent a DDoS attack, create a DDoS prevention plan by going through a security assessment.

6. Computer Worms

   • Computer Worms are quite dangerous software that spreads from one computer to another to create botnets. Most of the time, they don’t target files.

7. DDoS Attack

   • SQL Injection is a code injection technique to allow the attackers to tamper with existing data or spoof identity by exploiting a security vulnerability in the victim’s computer.

8. Social Engineering

   • Social engineering is where you manipulate unsuspected users to give up confidential information. Criminals usually want your passwords and bank information or even your whole computer.

9. Brute Force Attack

   • Brute Force Attack is an aggressive attack that hackers use to guess the victims password.
     • To prevent this, people have to enable two step verification which is a system that is added. This system will make it so an attacker would have to pass the second verification test such as a code going to the user's email which they may not have access to. Make sure that you also have a strong password that contains different characters so that its harder for the hacker to get access. You can also enable a locking method which will prevent the hacker from trying to guess your password after multiple tries
