Why we should be thankful for hackers
Four years ago, a hacker named Barnaby Jack, found a way to make ATMs throw money at him. And in the vote between Trump and Theresa May, a country made a professional hacker to change the results. We often terrified by these powerful hackers around the world. However, hackers aren’t all bad guys, nor are they all f ocused on breaking into places they shouldn’t be. Instead, most hackers in the world are focus more on how to make us people to live a better life. So I am here today because I think we need hackers for two reasons.
The first reason is that Hackers are the immune system for Internet. Hackers, can be divided into three types: the write hat hackers, the grey hat hackers, and the black hat hackers. The black hat hackers are aimed to break into internet systems for money and authorities. On the other hand, Gray hat hackers, are do it for personal recognition or just for fun. It's the white hat hackers that really do good work. They hack into the internet system and web sites in order to help those sites’ administrator test and improve their security level, so that the oth er types of hackers can’t access so easily. All three groups use the same methods, but their motives are very different. So, in fact, this kind of hackers can be called ‘the immune system’ for the information age. They prefer to find those hidden threats in our world, and then make us fix it.
The second reason is that Hackers are definitely the skilled professionals. No doubts, they are fantastic coders. Our government often use hackers to solve crimes and arrest criminals. They even track us, monitor us, so the government can easily improve our social stability.
So, it’s time we take an objective view at hackers, because if we keep expecting them to be the bad guys, how can they be the heroes? Let’s be thankful and respectful to hackers, they can create a better and security sociery for us.。
