Cybersecurity is all about protecting computers, servers, mobile devices, electronic systems, networks, and data from harmful attacks. It’s also called information technology security or electronic information security. Its main goal is to keep your digital world safe and secure.
In this article, we will discuss about Cyber Security. We will learn the basics of Cyber Security, what is Cyber Security, history of cyber security, how it works, types of cyber security, tools that are used in cyber security, services that cyber security provides, advantages, disadvantages, and limitations of cyber security, and other concepts as well. So without wasting further time, let’s get started with Cyber Security.
Cyber security is also known as information security or electronic information security and it is used for defending computer devices, mobile devices, servers, electronic systems, networks, and data from cyber attacks.
It uses technologies and policies to ensure the confidentiality and integrity of sensitive data. The aim of Cyber Security is to protect organizational and individual sensitive data from threats. Threats may include cyber-attacks, data breaches, malware, viruses, phishing, and cybercrime. There are so many security measures like firewalls, intrusion detection and prevention systems, encryption, and access controls. Cyber security plays an important role nowadays. Almost all organizations rely on computer systems and networks for storing and processing sensitive data. Cyber security is a rapidly evolving field, and also new threats and technologies are emerging side by side.

Types of Cyber Security
Cyber security has several types. Some of the common types of cybersecurity are the following:
Network Security
Network security is focused on the protection of networks from unauthorized access and attacks like firewalls, intrusion detection and prevention systems, and VPNs.
Cloud Security
Cloud security is focused on securing cloud infrastructure. Some services as well like SaaS, PaaS, and IaaS, are from security threats. The threats may be data breaches and insider attacks.
Mobile Security
Mobile security helps to secure mobile devices like smartphones and tablets from cyber-attacks and data theft. Increase in the use of mobile to access sensitive data and perform critical tasks.
Endpoint Security
This security is focused to protect devices like laptops, desktops, mobiles, and tablets, from security threats. Threats may be malware and phishing.
Application Security
This security focused to secure applications and software from security threats.
IoT Security
IoT security helps to secure the network and devices that make up the IoT ecosystem.
History of Cyber Security
Talking about the history of cyber security, In the 1960s and 1970s, cyber security originated. At that time, only computers became widespread, and security arose.
In the 1980s and 1990s, there was a rise in personal computers and the internet. Cybercriminals began to target individual users and organizations with viruses and worms. Due to this issue, anti-virus software was developed. In the early 2000s, cyber attacks became more sophisticated and targeted with the emergence of advanced persistent threats (APTs). Due to this, new security technologies developed, like intrusion detection and prevention systems (IDPS) and security information and event management (SIEM) systems. Today, cyber security is increasing rapidly with new threats and technologies emerging.
