In the animation “Finding Nemo,” the main character, Nemo, asks questions about the sea and where he lives. “What is the sea?” Hearing this, the dolphin puts Nemo on its back and jumps over the water to reveal her world. When you are in the sea, you do not know what the sea is. However, when you rise above the surface, you can see that the sea is a place where water gathers at a low level, and above it are air and land. She eventually realizes that she is also on the ground with water. If you want to understand the essence and grasp the reality, you must step out of the place you belong to for a while. Further development and reform can be expected. - 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"
