Cyber Security

I have read the 'Cyber Security' on Shelly Duncan's blog These days, ‘cyber world’ is a kind of another society as real world. We used to buy or sell our goods and exchange information. Moreover, we can be learned many things through an Internet like a distance learning class. We, sometimes, expose our private information such as social security number or credit card number, and then this could make a trouble. This trouble is not only for individual. Sometimes there is a big problem at the level of nation or world. Last month, I read an article which North Korea attacked government websites in the United States and South Korea. According to the article, “South Korea intelligence officials have identified North Korea as a suspect in those attacks and said that the sophistication of the assault suggested it was carried out at a higher level that just rogue or individual hackers.” Also, “Targets of the most widespread cyber offensive of recent years also included the National Security Agency, Homeland Security Department and State Department, the Nasdaq stock market and the Washington Post, according to an analysis the software used in attacks.” These institutions influence to our society powerfully and have a higher security than other individual websites. That is, most website in the world can be hacked by an enemy. So, we should strengthen our websites as much as possible. Obama administration emphasizes “Cyber Security” and asked for a 60-day review of structures for cyber security. As the author of blog said, government should protect Americans from cyber threat, and Americans also need to know that there is a threat or risk. One more thing which I want to add is that the Cyber Policy should revise more frequently than other policy because the speed of development of computer skills is even faster than what we expect. Also, government should make easy to contact their information or warning to the public even for a beginner. Even if we make secure the cyber world, it might break out another problem. So, government should invest people who can take care of the problem to improve skills. And, to cooperate with other countries can be one option to protect people from troubles.
