Define Cyber Security and its history Solution Please follow the data : CYBER SECURITY : Cyber security, also referred to as information technology security, focuses on protecting computers, networks, programs and data from unintended or unauthorized access, change or destruction. It can also be referred to as the body of technologies, processes and practices designed to protect networks, computers, programs and data from attack, damage or unauthorized access. In a computing context, the term security implies cyber security. HISTORY : In the past, with the advent of many malicious viruses and different types of trojans/malware, it was not an important feature to think that with the invention and introduction of networks and the world wide web, security wasn’t always a top concern. In fact, in the very early stages of ARPANET, a packet-switched network funded by the Pentagon, a number of intrusions were said to be made by high school students. This was back when cyber security didn’t exist, and it was the first in a long line of attacks that prompted computer scientists all around the world to take action and implement security measures and introduce cyber security to help people around the globe. Since the internet nowadays is almost everywhere, the accessibility and connectivity has increased with the days, the opportunity have also increased parallely. Back then, only a few people know how to use computers and there is no reason in assaulting them. Now, anyone can use a computer and there are many ways to use them like networking, online gaming, and banking and money transactions. And when we look back to the past, cyber criminals were almost always more sophisticated than those individuals who are trying to deter them. And even if companies have IT security, there are only few security professionals/security graduates and much fewer security tools available against threats. Today the story is almost the same, criminals may have grown more dangerous and has many ways to accomplish their dark deeds, but for some reasons the threats they pose have been greatly reduced, compared to as before. So with the advent of cyber security mor eand more number of tools has been introduced and implemented so as to maintain a healthy relation with internet without any atrocities. Hope this is helpful. .
