What is Cybersecurity?
Table of Contents

Cybersecurity can be described as the protection of computing systems’ confidentiality, integrity, security, and availability. It is the practice of providing security to networks and systems in order to protect them against cyber attacks.
According the definition of cybersecurity by Comodo, (blog/cyber-security/what-is-cyber-security.php) :cybersecurity is the practice of protecting systems, networks, andprograms from digital attacks. These attacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes.Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative.
Cyberattacks are on the rise. They target data access, modification, or deletion, as well as money extortion and disruption of normal services. Cybersecurity is a major concern for businesses today, as there has been an increase in the use of information technology to improve efficiency and effectiveness in business operations. The current business environment is so complex that there are many systems, users, networks, and devices.
Cyber criminals target all of these targets and have devised multiple methods to stop them. Cyberattacks are becoming more sophisticated and effective. Cybersecurity is now a necessity rather than a luxury for many businesses. Cybersecurity is made up of multiple layers that cover devices, networks and systems as well as users. These layers are designed to protect these targets from being compromised by attackers. These layers can be grouped into three categories in organizations: people, processes and technology.
People
This category includes users. Users are notoriously weak in the cybersecurity chain. Cyber criminals know this and target users rather than systems during attacks. Users are responsible for creating weak passwords, downloading attachments to strange emails, and falling for scams.
Processes
This category includes all processes used by an organization. These could include business processes such as the supply chain that could be exploited to gain malware inside companies. Sometimes supply chains can be targeted by attackers in organizations that are well protected against other attacks.
Technology
Technology refers to both the software and devices used by an organisation. Cyber criminals have made technology a major target and have devised many ways to make it more difficult. Although security companies strive to stay abreast with the latest threats facing technology, it seems that cyber criminals have always possessed the upper hand. Cybercriminals can source new types and variants of malware underground and use them in multiple attacks on different technologies.
Cybersecurity is a broad field
It is hard to overstate the importance of cybersecurity. The world is interconnected, so an attack on one user or host can easily turn into an attack against many others. Cyber attacks can be anything from theft of personal data to extortion attempts against individual targets. Many things are at stake for companies. Companies are always at risk. There is a wide range of cybersecurity coverage available for individuals and corporate organizations. Let’s take a closer look.
Cybersecurity Terminologies
Here are some terms that relate to cybersecurity:

Types of cybersecurity
Cyber Security can be classified into these types:
#Information Security
Information security is designed to protect users’ private information from unauthorized access and identity theft. It protects data privacy and hardware that transmit, store, and manage that data. User authentication is an example of information security.
