What is Cyber Security | Definition, Types & Best Practices [Updated 2024]

Due to the extreme level of online threats and risks, Cyber Security has become the need of every individual and business globally. One of the reasons is the heavy data loss due to data breaches. We need cyber security to protect our databases against unauthorized online access.

Behind all these attacks are adversaries who are extremely experts at hacking networks, systems, and devices with the latest hacking techniques. To stop them, we got the support known as “Cyber Security Experts” working in the world with the latest cyber security techniques and tools to enhance security against online threats such as

If you want to learn more about cyber security fundamentals, you can read this article which is specifically based on the latest updates in the information about the relevant subject with the challenges. Let’s continue!

What is Cyber Security?

It is the process of securing various resources, such as networks, systems, servers, databases, programs, and devices, against online threats executed with malicious intent. Generally, these attacks are objected at controlling, modifying, and destruction of confidential data while extorting ransom money from victims via ransomware. These attacks can slow down the process and operations of businesses using the resources to complete daily tasks.

What’s the Difference Between a Cyber-Attack and a Security Breach?

Well, both are from the same batch. However, apart from their similarities, they have differences in many factors. To understand those differences, you can read further.

Cyber Attack Security Breach
In this type of attack, a hacker tries to victimize resources. They try to exploit the network or system CIA via several cyberattacks. It’s a successful attack on resources for confidential data, unauthorized access, or disrupting operations. Their continuous attacking attempts once in a while succeed.


Security Breaches also point at a certain part of a complete cyber security planning known as Business Continuity and Incidence Response (BC-IR). It supports firms in dealing with cyberattacks.
