Cyber Security has become an important part of every company. This is because the need to protect your data from outsiders has increased due to the amount of illegal hacking that is performed nowadays. Regardless of type, size, scope, or industry, every company that wants to survive must be always ready to defend and protect its important data. The objective of Cyber Security is to secure your data from all threats. 

If we talk about the Cyber Security background, malware and network breaches have always been present and are used for malicious ends, but nowadays, data leakage is happening more professionally.

The answer to ‘What is Cyber Security?’ is that Cybersecurity identifies threats and safeguards information. There are many Cyber Security domains on which you work. More and more young professionals are coming forward to learn about Cyber Security concepts and how Cyber Security works.

This article contains all about CyberSecurity:

1. Definition of Cyber Security

To answer the question ‘What is cybersecurity all about?’, Cyber Security means the measures and techniques of protecting computers, networks, programs, and data from unauthorized/illegal access or attacks that are aimed for exploitation and loss. Some Cyber Security examples are coding, authorization, encryptions, network security, etc. 

2. Why Cyber Security is Important?

Cyber Security is important as it protects our sensitive data and information, both governmental and industry information systems, from misuse, theft, and damage attempted by hackers and criminals. 

3. Why do we need Cyber Security?

It is very important to have good Cyber Security in place because attacks like email spoofing and identity theft can cause a loss of millions to a company. Cyber Security prevents attackers from getting inside your systems and servers. This is one of the major advantages of Cyber Security.

  • One of the needs of Cyber Security is that it helps you to identify threats and attacks in advance so that you can prevent and respond to such malicious acts before any major damage occurs.
  • New and upgraded versions are adapted by the hackers frequently. They keep on updating themselves. If you fail to equip yourself then there is a chance for them to win. So, keeping updated Cyber Security in place gives you a chance to protect your data and at the same time, gives you a feeling of safety so that you can concentrate on other work freely.

Due to the increase in cyber attacks, the question of ‘Why Cyber Security?’ is being asked frequently and thus it is becoming more popular and in-demanding day by day. If you want to be in the race, then you must have proper Cyber Security management in place.

4. Challenges of Cyber Security

  • Expanded Attack Opportunities for Hackers– Cyber Security is dealing with the challenge of increasing overlap between the physical and virtual worlds of information exchange, such as driverless cars, factories, smart TV, fridge, medical pacemaker, etc.
  • Complicated Regulation– The political discussions going on all over the world regarding data privacy and other related regulations also shed some light upon matters that raise challenges for Cyber Security. 
  • Lack of IT Talent– A crucial challenge of Cyber Security is the lack of talented and qualified professionals. Experts on Cyber Security are difficult to find and the people who know this expertise, know-how valuable they are. Thus, they charge heavy fees for their job that small enterprises may not afford. 

5. What are the types of Cyber Attacks?

List of the types of Cyber Attacks and Threats –

1. Phishing Attacks These kinds of attacks usually steal data, such as credit card details and login credentials. Spear Phishing attacks target a person or organization for desired information or data, and it is not a random pick.  Whale phishing aims at high profile employees like COO, CFO, etc., for data/information.

2. Malware Attacks It is a code that affects a compromised computer without the knowledge of its user. Some of the attacks are:

  • Ransomware Attack- This attack blocks the data of the victim unless he pays a particular ransom but there is no guarantee that the hacker will keep his words after receiving the ransom. 
  • Drive-by attack- In this, the hacker or attacker looks for the insecure and weak website and plants a malicious script in HTTP or PHP in one of the pages. 
  • Trojan Horses- This kind of malicious software generally appears common and looks useful. This software encourages the victim to install.

3. Web Attacks

  • SQL Injection- Malicious codes are employed to manipulate the backend database for information.
  • Cross-site Scripting- In this kind of attack, the hackers send malicious scripts into contents from trusted websites.

4. Distributed Denial-of-Service (DDoS) Attack – The objective of this attack is to shut down a network or service and make it impossible for the user to access it.

Some other types of Cyber Security Attacks are-

5. Password attack – Intention of obtaining or decrypting someone’s password illegally.

6. Eavesdropping Attacks – In this, the hackers try to steal the information which digital devices like computers, smartphones, etc., send or receive.

7. Inside Threats – These malicious attacks are done by the insider individual who is authorized and has access to the system.

8. Man-in-the-Middle Attacks – The hacker controls the communication between the two legitimate parties. Communication between both parties goes on as usual, without knowing that it has been controlled and intercepted by someone.

9. Artificial Intelligence (AI) Attacks – Machine learning software enables the computer to perform a particular task on its own. Hackers can get into the system and make it work on their will. In Cyber Security terms, this can be attacked like password theft, identity theft, etc. 

6. What are the types of Cyber Security?

Five different types of security are:

1. Critical infrastructure security –

These kinds of Cyber Security techniques are used in modern societies, for example, electrical grids, hospitals, etc. Here, physical systems and servers are protected from attacks to secure data and essential information.

2. Application security

It is one of the cybersecurity measures that should be included. Application Cyber Security works by using hardware and software to protect the data from threats that can come during the process of developing an application or software.Some of the Cyber Security software tools which helps in preventing unauthorized access –

  • Antivirus programs.
  • Firewalls.
  • Encryption programs.

3. Network security

           It is a type of Cybersecurity meaning, to make sure that inner networks are safe by securing the infrastructure and preventing any illegal access to it. Network administrators continuously add security and upgrade them so that no unauthorized personnel gets access to the network. Examples of network security are new passwords, extra logins, firewalls, etc. 

4. Cloud security

This is a Cyber Security software that precisely focuses on the safety of data stored on the Cloud. It requires less manpower and costs less as huge data center on-premises are not required. 

5. Internet of things (IoT) security

To define Cybersecurity of this kind, physical devices like, sensors, wifi, and other devices that are connected to the internet are secured from unauthorized personals. Normally, these devices have a very less security patch, therefore, securing them is of utmost importance.


We all know the dangers and threats these hi-tech Hackers possess. But, we can easily dodge or fight with them if we have knowledge about the basics of Cyber Security and have Cyber Security applications in place. There are many Cyber Security applications present that can secure your network, websites, and devices.  

The hackers keep on updating themselves and if a company wants to safeguard its data and systems, then they must have a proper and updated Cyber Security system and technology in place or the consequences may lead to heavy financial loss and other related issues. Hope that article answered all your questions on Cyber Security like ‘What is meant by Cyber Security?, history of Cyber Security, and its importance.
