Rarely does an erected flag fly alone. An invisible wind moves it, meaning an external force. When the wind blows, flags flutter, dust rises, and laundry dries. Many changes occur in response to one external factor, but we cannot see the cause. Eyes capable of reading invisible external causes can respond to a world of rapid change. We cannot attribute a cause solely by observing a phenomenon; instead, we must recognize a specific pattern across multiple phenomena. The ability to detect hidden commonalities is a form of wisdom. - 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"
