If you’re running multiple businesses within a single business entity or a business that generates sales by connecting with different businesses, I recommend managing the accounting for each separately. For example, if a car rental company also engages in car leasing, try to maintain distinct accounts for the rental and leasing sectors. This approach increases the chances of uncovering hidden costs or mistakes in resource allocation. In business, specific attributes necessitate this separation, leading to independent costs and improved profit structures. Neglecting this reality can result in bankruptcy without fully understanding the reasons behind it. The foundation of success is to avoid failure. - 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"
