One of the most important aspects of the growing digital world is cyber security. Cyber Security is a strategy for digitally protecting any device, network, system, and program, as well as ensuring access to certain confidential integrity and information. In this article, we discuss Cyber-Security, why it is so crucial, Cyber-Security Threats, and Cyber Security Tips.

What is cyber-security?

Cyber security is a piece of technology, process, and practice that is used to protect networks, devices, programs, and data from various cyber-attacks, data theft, loss, and unauthorized access. Cyber ​​security can also be called Information Technology Security or Computer Security.

Information Technology has made our life and work easier. Almost every government and non-government organization, large and small companies, involve different types of important information that are stored in their devices or other data centers. For example – personal information, financial statements or information, confidential information, confidential files, documents, and so on.

When we use the Internet or are connected to any network, there is always the fear of various dangers. When a computer device is connected to the Internet, it has to be joined to a huge network all over the world. Through this network, a hacker can enter the computer through various means and there is a possibility of stealing the important data and files or destroying them or can use our data illegally or incorrectly.

Cyber ​​security is the process of protecting your device and network within the Internet. Cyber security is used to protect a computer device, network, servers by preventing such dangers. Hopefully, everyone understands what cyber security is.

Why is cyber security so crucial?

In the world of information technology, our reliance on the internet has increased day by day. This gives the fraudsters ample opportunity. If we are not careful, it will not take long for our money or important data to fall into the hands of fraudsters.

According to the Forbes report, cybercriminals have earned $ 2 trillion through cybercrime by 2019. It could be $ 6 trillion if the need for cyber security is not understood. This understanding is not enough. It is essential to take appropriate action against cybercrime.

If we think we are safe and why we need cyber security. It is completely wrong if only large organizations fall into the trap of theft by hackers or some malware. The average consumer, who stays connected to the internet without being careful enough, can easily fall into this trap. Because hacking Internet-connected devices is only a matter of minutes and that is why cyber security is so important.
