What is cyber security and why is it so important in today’s world? The answer is that cyber security is a process which helps the users to protect their data, systems, devices and network from digital threats. These threats include loss of data, unsafe systems, hacking, loss of financial means and cyberattacks. To protect yourself from these malpractices the users can implement certain measures such as encryptions, firewalls, multi-factor authentication systems, security audits, backups and recoveries, response plans and training of security policies.

History Of Cyber Threats

The history of cyber-attacks dates to the early 1970’s, when the first ever hacking incident took place. In this incident several individuals-initiated computers hacking to access data from the systems of other people. However, this hacking was not intended to malpractice, but just to conduct an experiment on the possibility of hacking into other people’s systems.

The second incident took place in the era of 1980’s, the most well-known incident occurred called as Morris Worm. In this hack, the hackers initiated a disruption on the world wide web. Later in the 1990’s, hacking became very famous in the internet community and hackers used the methods of sending viruses in the systems with the aid of emails and infected files. In recent times hacking has become very technologically very advanced. This advanced hacking is done through malpractice which is widely known as phishing. In this sort of malpractice, the hackers create a false link or website, as soon as you click or access the link all your information is accessible for the hackers. Lastly, the hackers in the modern world are incorporating artificial intelligence and machine learning to improve the practices of hacking.

Key Concepts Of Cybersecurity
