1. Viruses. The most popular that almost everyone has encountered in their life. While some people consider cybersecurity threats to be viruses, that's not entirely true. A virus is malicious code that is downloaded onto a computer without the user's permission. It can attach itself to other files and spread over network. One of the main goals of cyber security is to prevent such threats.

2. DDoS (Distributed Denial of Service). This threat attempts to disrupt normal traffic and website by flooding the system with as many requests as it can handle.

3. Malicious Software. This term refers to a program designed to harm a computer. These include viruses, spyware, Trojans, social engineering and worms.

4. Network Worms. No, this is not the game we all loved to play. It's like a virus. They can multiply like viruses but do not attach themselves to computer program files. They look for computer vulnerabilities and report them to the creators, who take appropriate action.

5. Trojans. Another popular threat that most of you have heard about. This is a type of malware that pretends to be a legitimate program. It can come in the form of a virus removal program but instead performs suspicious activities after getting installed and started.

6. Social Engineering. This is a threat that is used to deceive and manipulate users into gaining access to their PC. This is achieved through malicious links or physical access to the computer. This can cause serious problems for many companies if they don't know what cybersecurity is.

7. Phishing. This is a form of social engineering that attempts to obtain sensitive or confidential user information.

8. Spyware. It monitors your computer activities and collects personal information. Spyware or adware can be installed through malicious links, programs or applications.

9. Ransomware. It can be considered as the fastest growing cyber security threat. This is a type of threat that requires you to pay after encrypting user data, thereby making it inaccessible. It should be noted that paying ransomware does not guarantee recovery of encrypted data, so be careful.

10. WED. This threat occurs when a user exposes themselves to an insecure network. This is called MITM because the cyber criminal injects himself between the user and the server. The user submits information through a hacker without their knowledge.

11. SQL injection. This happens when an attacker injects malicious code into a server that uses SQL. Such injections are only successful if there is a security breach. If there are any, the attack will lead to access to the data.

By now you should have a better understanding of what cybersecurity is and what it does. Its task is to prevent all these threats to the user - there are quite a number of such threats. There are many cyber attacks, but this list is only the most common.
