Top 6 Terminologies that are commonly used in Cyber Security

With many of the world’s largest and most cutting-edge businesses falling prey to cyber assaults in the previous five years, cyber security has become a worldwide sensation.

In that light, sensitive personal data such as social security numbers, identification documents, bank and credit card details, and personal data breaches can affect millions of people.

Unfortunately, we are still at risk of our digital data being stolen and skewed even if computers don’t exist. However, living in a digital world isn’t as daunting as you may believe – especially if you understand what you’re doing.

It might not be as challenging as it sounds to figure out how your gadget works. However, suppose you were able to solve the fourth-grade division. In that case, you can master cyber fundamentals that will get you quite far on your own in personal security and company security.

When it comes to being a cybersecurity expert, not only do you have to have the skills to do the task, but you also need the lingo. This is hardly news, given that whenever a new area of study emerges, it always creates its jargon, acronyms, and phrases

You project an image of experience and competence by talking about cyber security and using its terminologies. After all, stating that “the system has been hacked due to spyware introduced by a Black Hat hacker” implies you know what you’re talking about, and it also means that you can resolve the problem.

Explaining that the computer-thingy isn’t working because a bad guy with no connection to the company has stuffed it with malware won’t inspire much trust.

Before diving into the cyber security terminologies, let’s first understand the difference between a hacker and a cracker.

That said, let’s move on and help you get up to speed by offering a list of the top 6 terminologies used in cyber security that you should know.

  1. Cloud
  2. Any file or service can be accessed via the internet from anywhere in the world using this technology. It’s a collection of computers with massive storage capacities that remotely responds to requests. Instead of personal computers, data is stored on servers.

  3. Botnet
  4. A term for ‘robot network’. It’s a collection of compromised computer systems and internet-connected devices (e.g., security cameras, DVRs) that third parties can remotely control. Usually means something along the lines of an attack or malware spreading across many different victims’ computers at once to perform some nefarious activities such as sending spam or launching a distributed denial-of-service (DDoS.)

  5. Data Breach
  6. This term generally refers to the illegal access and use of protected data. Often, this can mean access to sensitive information such as credit card details and social security numbers. This may cause harm to the person whose identity has been stolen.

  7. Domain
  8. A group of computers, printers and devices that are interconnected and governed as a whole. For example, your computer is usually part of a domain at your workplace.

  9. Exploit
  10. The phrase “exploit” refers to a piece of computer code that takes advantage of a flaw or vulnerability to produce unintended or unanticipated behaviour. An expert hacker may use one or more exploits.

  11. DDoS
  12. A DDoS assault is an Internet cyber attack in which the aggressor tries to shut down a machine or network resource from authorized users by disrupting their services. The flood of incoming messages forces the target computer to slow down or even crash from being overloaded with data. These attacks cause increasing economic losses, but it’s difficult to calculate them because many go unreported.


Cyber security is a vast subject, and these six terms barely begin to scratch the surface. If you want to be seen as a serious cyber security professional, you should at least learn what these mean inside and out – and sound like an expert when you use them.

There’s a lot to cyber security, and it can be challenging to understand everything fully. It’s no surprise that the average business person and consumer aren’t well versed in all of these terminologies; however, knowing the top 6 terminologies listed above will help you get up to speed much faster.

The next time you’re talking with someone about cyber security, try using some of these terms (and impress your listener.)

Good luck!
