Top Cybersecurity Types You Must Watch in the 21st Century


Various types of cyber threats plague today’s technological world. But knowing cybersecurity types, simple tips, and potential educational opportunities are essential. 

In today’s high-paced world, the growth of cybercrimes is exponential. They hit a sheer amount of ventures and individuals every single day. Even attackers have become equipped with the evolution of cyber security types. 

Any potential attack that disrupts digital information, operations, or misuse of data counts as a cyber security threat. It can be sourced from multiple actors, corporate spies, harmful groups, or organizations. Thus, sensitive data has not remained aloof from these people. 

Cybersecurity Types

Below are Top 5 Cybersecurity types you must be aware about

Password Attack

This is one of the cybersecurity types one needs to know. Do you often consider your documents or accounts secured after using passwords? The reality can be quite shocking as this method is not safe at all. Even simplified tactics can allow attackers to gain access to confidential information. 

By doing so, they can manipulate any given system. Cybercriminals adopt many techniques to crack passwords, and some of them include social engineering, casual guessing, and having access to a password database. 

Guessing passwords is not a cakewalk as it takes place through a systematic process. Known as a brute-force attack, it uses a program to attempt all possible variations or combinations. This can be highly effective at times, especially if the login credentials are not much strong. 

Another similar method is the dictionary attack when cybercriminals try to use a list of common passwords. It can further allow effortless access to any given computer or network. However, this issue can be solved by deploying effective cyber solutions. 

The best practices include multi-factor authentication and account lockout. With the first method, one can add an extra layer of security to their account or network. On the other hand, the latter option allows users to freeze their accounts after multiple invalid login attempts. 

Denial of Service

One of the popular cybersecurity types is Denial of Service. Popularly known as DoS, it is one of the most prevalent types of cyber security attacks. It leads to over flooding of any system or network till it can not reply to any request. A distributed version of this threat possesses a similar functionality. 

The only difference comes when the attack originates from a given cyber network. Attackers also engage in flood attacks to ruin the handshake process. Other techniques can also be performed simultaneously to trick the users.

They get sufficient time to disable a given network to enable other attacks. For instance, a botnet is a sub-category that lets millions of systems be infected with malware, and hackers gain complete regulation over the given matter. 

They are also called zombie systems by information technology specialists. Thus, they tend to attack and overwhelm the capabilities of any target’s processing. They can be found in multiple locations and cannot be located easily. 


Have you ever heard about the words worm, virus, or trojan? All of these are just some cybersecurity types or threats classified under malware. Let us have a look at their brief description and functioning. 

  • Trojan: It is a type of non-reproducing malicious code that is disguised on multiple occasions. It can be further disguised as a given program to be installed by multiple users. After that, the users select a fake executable, and the program is further implanted into the hard drive. The rest of the damage is caused afterward. 
  • Virus: Viruses generally deploy a standalone software program in the form of their vehicle. A component of malicious code is implanted into the system to take steps against a given computer or network. 
  • Spyware: This sort of cyber incident watches on unwitting individuals and collects data from their systems without their knowledge. Spyware can often record your keystroke or analyze the data you transmit over the internet.
  • Worm: Here comes a type of malware that can be reproduced and shared from one device to another. It is just a singular piece of software that has harmful consequences. 

Thus, malware attacks are becoming more prevalent than ever. Individuals must gear up to prevent these threats on their computer system or network. It is crucial to be diligent while using the internet, and you should avoid clicking on any suspicious link, popup, or email. Anti-malware software should be installed and updated over time. 


Yet again one of the popular cybersecurity types is Phishing. It is yet another type of significant cyberattack that incorporates sharing massive fraudulent emails to unsuspecting users. It is often disguised as a reliable source and can be deployed easily, and the legitimacy can be suspected by having an almost lifelike appearance. 

However, it gets linked with the recipient, particularly to a malicious file or script. Granting access and control to the targeted device is also fulfilled by these attacks. Installation of harmful files, extraction of data, and proper implementation takes place. 

These threats also occur through social networks, online communities, and direct messages. Attackers successfully gain information by leveraging social engineering, and they would have a deep insight into your interests, activities, and work. 

Some types of phishing attacks include pharming, whaling, and spear phishing. Surprisingly, these cyberattacks can take place via phone calls or text messages as well. Despite the type, the aftermath is often shocking to the core. 


Answering “how many types of cyber security” is not sufficient to find its solution. Organizations and individuals must follow proper guidelines to not become a victim of these threats. Keep your credentials always secured and update them regularly. 

Be sure that no unauthorized person or enterprise has control over your devices and data. Avoid opening suspicious messages or links. It is best to think multiple times before being a victim of such attacks. There is no denying that both public and private businesses are vulnerable to multiple threats. 

However, regular employees can alone not manage the cybersecurity services, which is one reason why organizations hire cybersecurity specialists for this purpose. Thus, you can get a degree in IT or computer science to enter this venture.
