The ice does not sink; it floats on the water. Water and ice, which are the same substance in different states, can be regarded as fundamentally the same material; yet, they have entirely different effects in practical applications. Many things in the world are the same yet different. Just as a cat likes mice but doesn’t love them, likes and loves are distinct concepts. We often overlook that these subtle differences can lead to significant results. - 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"
