The process of preventing digital attacks from protecting the systems, networks, programs, etc., is called cybersecurity. The main goal of cyberattacks is to access, change or destroy the information, exploiting the users for money and disrupting the processes in the business. Implementing efficient cybersecurity measures is challenging because the number of devices is more than the number of people, and the attackers are becoming more creative. The data that needs to be kept safe in computers, networks, and programs are provided with multiple layers of protection by the cybersecurity approach. An efficient defense can be created against cyber-attacks if the people, processes, and technology complement one another in an organization.
The necessity to learn Cyber Security
A huge amount of data is collected, processed, and stored on computers in government, corporate, military, financial, and medical organizations, and it is important to protect such data. Hence cybersecurity is important. The major portion of such data is sensitive information to be protected from unauthorized access. If not protected, the consequences could be negative. The sensitive data is transmitted across networks and other devices while carrying on business, and the protection of such information and the system used to process and store such information is done by cybersecurity. With the increase in the growth, volume, and sophistication of cyber-attacks, those companies, and organizations protecting the data related to national security, health, financial records, and other sensitive information, must take measures to protect their sensitive data and information.
The applications of Cyber Security are:
Phishing is an example of cybersecurity. It is the technique of fooling the target into taking a harmful action through emails crafted by cyber criminals. The receiver is tricked into downloading the malware, which is in the disguise of something important, like the user is tempted to click on the link that takes them to the fake website extracting personal information like usernames and passwords related to banking. Cybercriminals send phishing emails to thousands of users who seem to be potential victims.
