Cybercrime is increasing day by day. To get rid of this we need Cyber Security. The Internet is accessible by most of the people today. Due to which online security is a great concern. Surfing the internet in a safe way is important. Cyber Security helps us to understand what are the malicious things we can encounter on the internet. Hence, aware us about the malicious content online. There are many terms in Cyber Security that we should know. This would help us to broad our knowledge about Online things.

Ensuring Online Security is easy, but sometimes we get worried about online Security.

What Is Cyber Security?

Cybersecurity refers to a set of techniques used to protect the integrity of networks, programs and data from attack, damage or unauthorized access.

Types of Cyber security threats

  • Ransomware is a type of malware that involves an attacker locking the victim’s computer system files. Further, demanding a payment to decrypt or unlock them.
  • Malware is any file or program which harms a computer user, such as worms, computer viruses, Trojan horses and spyware.
  • Social engineering is an attack that relies on human interaction to trick users into breaking security procedures in order to gain sensitive information that is typically confidential.
  • Phishing is a form of fraud where fraud emails are sent that resemble emails from reputable sources. However, the intention of these emails is to steal sensitive data, such as credit card or login information.

Above mentioned threats are common. You can clearly see these threats happening. You may be familiar with these threats. In cyber security, these attacks include some terms. These terms in cybersecurity should be known to you.

Common Terms In Cyber Security and Cybercrime

1. Cloud

Cloud refers to an online storage space. This Cloud Storage act as normal storage. The only difference is that it is not present on Cloud or Online instead of your PC or Mobile. Cloud storage is helpful. This storage ensures data safety. Your data is kept safe from theft and loss. If you choose a good cloud provider then you can have peace of mind.

2. Domain

Domain refers to a group of different Computer components connected together. For example, In a company, there is a domain which contains different PC connected to each other.


3. VPN (Virtual Private Network)

Virtual Private Network refers to a virtual network. This virtual network is used to connect anonymously to the Internet. VPN is an important part of Cyber Security. Moreover, Cybercrime is mainly committed by using a VPN.

VPN helps the user to hide its original IP by the set of algorithms. Hiding IP prevents the user to be directly tracked by the attackers. Though Govt. is still able to track you if they want. But you are safe from the attackers.

There are many VPN service providers. You can choose anyone from the list. But we suggest you go with the reputed one. Consequently, they will provide you with better security.

4. Exploit

In simple words, exploit is a loophole in any program or item. Exploits are the main reason due to which we can see several cybercrimes taking place. These exploits can be big or small which can result is a cyber attack. To avoid cybercrime (s) companies constantly look for their exploits. When they found one. They instantly remove it.


5. Breach

Exploits and breach are co-related to each other. If there is an exploit and a person uses it. Then they can easily get unauthorised access to the system which is known as Breach.

In a similar way, a hacker uses an exploit to breach into a system. After breaching he can clearly do whatever he wants. This can be a cybercrime (if done in an unauthorised manner).

6. Firewall

Firewall is the safety mechanism that prevents unauthorised access to your system. These act as a barrier between you and the other person who tries to breach into your system.

7. Malware

Malware is the malicious programs that can cause your system not to work properly. These are Virus, Worms, Ransomware etc.

8. DDoS attack.

Attackers use DDoS (Distributed Denial of Service) attacks to make a network unavailable. They do this by loading the targeted machine with massive requests from multiple devices. The target suffers a severely pack bandwidth, and later connections are impossible. These attacks are typically carried out by botnets.

9. Botnet

A botnet (robot and network) is a network of devices infected by an attacker. Botnets are generally utilising to perform tasks such as carrying out DDoS attacks, mining Bitcoins, and spreading spam emails. Nearly any device connected to the internet, including home routers, can be infected and pulled to act as botnets without its owner ever noticing.


10. Phishing

As the name sounds. Phishing is a way of catching people into traps. These traps can be fake websites looking original, promotional emails etc. Phishing is done to grab sensitive data from the user. Further, this data is either sold out or used for some malicious activity.

11. Ransomware

Ransomware is malware that encrypts your system. Sometimes attacking individual files. When you try to access the encrypted files you get a note which states that your storage or PC is not usable anymore. To unlock your PC you have to make a payment which is usually $600 on average. Further, the messages sometimes appear to be from an official government agency. According to which you have committed a cybercrime. This scares many into paying the ransom. Payment is often demanded in Bitcoins.

Recently, we have seen Wanna Cry attack Windows Systems. This is one of the examples of Ransomware attack. In this Wanna Cry attack, the victim is asked to pay a huge amount in bitcoin to unlock its System.


These are some terms in cyber security which are basic and you should know them. You may hear these terms in cyber security on a regular basis.
