The process of preventing digital attacks to protect 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. Implementation of efficient cybersecurity measures is a challenging task because the number of devices is more than the people and the attackers are becoming more creative. The data that needs to be kept safe in computers, networks, 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, medical organizations and it is important to protect such data, hence cybersecurity is important. The major portion of such data is sensitive information which is 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 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 to take a harmful action through emails crafted by cybercriminals. The receiver is tricked to download 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. Phishing emails are sent by the cybercriminals to thousands of users who seem to be potential victims.
