Real change happens so quickly that we often don’t notice when it occurs. The changing of seasons is a good example. Clearly, winter and spring are very different. It’s hot during the day and cold at night, but when we see spring flowers blooming along the roadside, we realize spring has arrived. We tend to think that big changes will feel different, but sometimes small signs reveal the change. For instance, when our foreheads sweat even with little movement, we recognize that the temperature is getting warmer. What changes might you not notice or recognize? Perhaps your weight? - Joseph’s “just my thoughts”
For the security of the Internet service, we have been asked by the Internet service companies to set the password combined by more than 8 or 10 "uppercase letter+lowercase letter+number+special character". But it was obviously of no use. This security guideline was recommended by Bill Burr who worked at NIST in the USA, he suggested this way in his report. Furthermore, the user was required to change the initial password set regularly. Despite this measure, the best way of security to protect users' accounts was the notification of the alarm for attempted hacking when the hacker tried. We have only tried to change the keys despite the simple method meanwhile. Today, the world has begun to comprehend that the security problem is not encryption or confidentiality, but simply cyber-dominion control and communication. - Joseph's "just my thoughts"
