Cyber Security is the body of technologies, processes, and practices designed to protect networks, devices, programs, and data from attack, theft, damage, modification or unauthorized access. It’s also known as Information Security (INFOSEC), Information Assurance (IA), or System Security.
Cyber Security is important because the government, Corporate, medical organizations, collect military, financial, process, and store the unprecedented amount of data on a computer and other properties like personal information, and these private information exposure could have negative consequences.
Cyber Security proper began in 1972 with a research project on ARPANET (The Advanced Research Projects Agency Network), a precursor to the internet. ARPANET developed protocols for remote computer networking. Example – If we shop from any online shopping website and share information like email id, address, and credit card details as well as saved on that website to enable a faster and hassle-free shopping experience, then the required information is stored on a server one day we receive an email which state that the eligibility for a special discount voucher from XXXXX (hacker use famous website Name like Flipkart, Amazon, etc.) website to receive the coupon code, and we will be asked to fill the details then we will use saved card account credentials. Then our data will be shared because we think it was just an account for the verification step, then they can wipe a substantial amount of money from our account.
That is why Cyber Security provides services as a Security Gate-Way to make information more Secure; in today’s time, hackers are advanced. We can’t surely say whether the data stored in my Devices is safe from outside threats. With Cybercrime increasing rapidly, it’s crucial to have Cyber Security in place in our personal life and our Business.
