Cyber security is a phenomenon that has an impact on everyone in this modern world. While everyone is talking about this subject frequently, you might still feel inadequate about it. If you believe there are some things that you should know about cyber security, and you feel embarrassed to ask them to people around you, reading this article would be highly beneficial for you.

What is Cyber Security?

When you are in a social gathering, and your friends are talking about cyber security, you might feel insecure to ask them about it. Before mentioning the key points of cyber security, we should explain its definition.

Cyber security is a kind of information security system that runs to protect networks, devices, programs, and data from malicious activities. A cyber attack and unauthorized access are the things that cyber security works against the most.

What is Cyber Security for?

Protecting data and decreasing the level of vulnerability of systems and networks are the main things cyber security works for. While these are the main tasks of cyber security, there are also other comprehensive duties of the system.

The tasks of cyber security can be counted like this;

  • Network security
  • Application security
  • Endpoint security
  • Data security
  • Identity management
  • Cloud security
  • Mobile security
  • Disaster recovery/business continuity planning

What Are The Malicious Activities That Cyber Security Protects From?

Before explaining how cyber security assures protection, you should know what it protects you from. Although there are many types of malicious activities, the most common ones are phishing, ransomware, malware, and social engineering. These activities show the importance of cyber security. Considering that attackers are more innovative in the modern world, this can be challenging.

While these malicious activities work differently, their common purpose is to damage the system, and steal information. Cyber security protects the network against all of them. By having a good cyber security system, and knowing hackers’ common tactics, you can protect your data.

How Does Cyber Security Work?

Cyber security is used by businesses to protect all of the computers, networks, and programs. To protect all of them, cyber security has a complex system. In addition to defined threats, cyber security protects against potential cyber attacks.

A cyber security system detects, investigates, and resolves threats by scanning constantly. To minimize the risks, the cyber security system continually examines the network. Cyber security system works in 3 steps, which are threat detection, threat response, and human augmentation.

What Are The Major Cyber Security tools?

Cyber security industry providers have many different tools to protect information better and decrease the vulnerability of networks. The most popular cyber security tools are network security monitoring tools, encryption tools, web vulnerability scanning tools, network defense wireless tools, packet sniffers, antivirus software, firewall, PKI services, managed detection services, and penetration testing.

There are also many popular cyber security vendors. These are some of the popular vendors you can have a look: Check Point, Cisco, Code42, CrowdStrike, FireEye, Fortinet, IBM, Imperva, KnowBe4, McAfee, Microsoft, Palo Alto Networks, Rapid7, Splunk, Symantec, Trend Micro, and Trustwave.

Why is Cyber Security So Important?

The importance of cyber security is being recognized more and more every day. Every business requires cyber security to be protected against attacks. Since cyber attacks run fast and rapidly, having a good cyber security system, and knowing how to protect your data in the first place are essential and necessary.

Data breaches affect the business in many aspects. The data kinds you protect with a high-quality cyber security system are personally identifiable information (PII), protected health information (PHI), personal information, intellectual property, data, and governmental and industry information systems.

In addition to the data breach, cyber security is important for fiscal savings. Economic costs, reputational costs, and regulatory costs of cyber attacks harm the business more than one can ever imagine. Even though having a high-quality cyber security system requires money, it is necessary for the future of the business.

What is The Key Approach to Cyber Security?

Even though the main purpose of cyber security is providing a defense against data breaches, there are also key concepts of this system, which are confidentiality, integrity, and availability. With these 3 approaches, cyber security provides a comprehensively planned data protection program. This combination of these three concepts of cybersecurity is also called The CIA Triad.

Confidentiality is essential for every workplace. It defines the limitation of access to information. Every business has many employees in different titles. So, while some of them can access some information, some can’t. While a cyber security system blocks unauthorized access, it also reports that attempt to the IT staff.

The second concept is integrity. This concept assures a consistent and trustworthy system running throughout time. Cyber security systems have proper data protection programs individualized for needs. Over the course of time, the running mechanism evolves according to the cyber threats. But it doesn’t become worse.

Availability of cyber security systems defines the maintenance. It upgrades itself automatically. Hence, the IT staff can reach out to the information anytime they want. Even though the system includes multiple layers, it is still easily available for an IT staff.


Cyber security is a significant need of the modern world. By knowing every aspect of cyber security, you can be assured of your security and protection. Because of the improvement of cyber attacks, data breaches have become more and more common every day. The only solution to preventing attacks is to have a high-quality cyber security system.

Even though you might not be familiar with the terms of cyber security, you can learn them by reading articles and attending some courses. In fact, cyber security is a highly complex system that can be used easily. All you have to do is pay attention and defend yourself from data breaches with a cyber security system.
