The word cyber means computer, virtual reality, or computer network. This word relates to information technology (IT, i.e., computers). This century is the electronic century where everyone's life and work depend on electronic machines, including mobiles, computers, and various other gadgets; therefore, it is important to secure and protect them internally and externally.

In this digital age (modern computing age), word cyber relates to all the aspects of computing, transmitting data, accessing data, processing data, and linking data. Three terms feature the word "cyber" – Cyberattack, Cybercrime, cyberspace, and cyber security.

Let’s understand these terms:-

Cyber-attack: Cyber-attacks are the unfair means of action taken by suspicious attackers to disable computers, size, modify or steal data and perform malicious activity to snatch confidential information without user acknowledgment. There are various cyber-attacks such as denial of services, email-spoofing, exploit, phishing, Man-in-the- browser, ping flooding, buffer overflows, spyware, etc.

Cyber-Crime: In this digital era, cyber-crime is one of the biggest threats people face, including large international companies, banks, and governments. Cybercrime includes a computer system with a network and illegal means of affairs achieved by criminal minds. Cyber-criminals execute cybercrimes by doing cyber-attacks.

Cyber-space: Cyberspace refers to the virtual world (internet world) where lakhs of computers are connected. It is a web made for interconnecting the computers via a network (internet) that has no shape, no design, and is beyond human imagination. It is a universe where communication is carried off via technology. It depicts how data transfers thousands of miles virtually beyond human imaginations.

Cyber security protects people, processes, and technologies by providing threat reduction, vulnerability reduction, recovery policies (including information assurance, computer network operations, law enforcement, etc.), international engagement of computer networks. It protects and prevents interconnected systems that include software, hardware, and data from cyber attackers. Therefore, cyber security is necessary in the computer world to prevent the system from cyber-attack, cyber-crime, and other vulnerabilities.

Cyber security is also referred to as information technology security. It uses technologies, devices, systems, software, programs to protect devices, programs, software from attack, theft, damage, modification, or unauthorized access. It is a bodyguard to information technology services and is termed IT security/ Cyber security.

Conclusion: In this physical world, we are living in a virtual data or digital era where data is everything. Data is a powerful tool that can make someone's life heaven and hell. Information or data is the base of technology, and with the extended use of technology, each information is digitally available or can be fetched out. Therefore every availability increases the threat of crime. We must understand that private information is at stake as we hear about data breaches and identity theft cases that affect millions of consumers. Cyber security plays a vital role in protecting data form cyber-attacks and alerting people from cyber-crime. Cyber security is not just only bound to organizations but also meant for personal computers, tablets, and mobiles because these are personally used by people that hold their personal information like photos, bank account details, property details, passwords, old records, etc. Cyber security is a gateway to seal the misuse of data and technologies. It guides the people about the protection importance of the data. Cyber security is a proper subject included in the learning of computer applications.
