Hello guys!
How are you? Hope you all are doing well. As we are livig in the arena of technology where we are hugely dependent on technology for our daily activities including machines, robots and many other tools. These advancements have revolutionized our lifestyle and made our lives more easier. However, along with all these benefits nations are using digital tools against each other. They are launching cyber attacks on each others' infrastrucure for the sake of their own country's benefits.
The Ukraine Power Grid Attack is the major case in point. During the year of 2016-2017 Russia's hackers shut down at least three power distribution stations. As a result , 230,000people lost their power conection and faced blackout. It is the first known cyber attack that proved countries could attack on their rivals through cyber technology without using missiles. Through these attacks one can easily destroy others economic, energy, and another country's important infrastrucutre.

Kindly share your ideas regarding this new security frontier.
