What are the trade-off choices between performance and security? A trade-off decision that many solution architects struggle to make is what requirements to compromise if security and performance requirements conflict? Something which I saw many times in my long career. One point of view is that good user experience is linked primarily to the performance of the system since it does make sense to provide good functionality but without a responsive system. On the other hand, some architects would see that providing a maximum level of security would give a better user experience. This may be true, but have they considered system performance while adding all security measures? Dr. Osama M. Khaled Sep 22, 2020 10:45 PM

The term “things” refers to living organisms or dummy objects that can be equipped with sensors, processing power and network connectivity. For example, smart phones are objects that can sense information from the world and transfer it to other objects. A smart phone can be used to read an RFID tag embedded in a board or a piece of clothes and gets information about it [1]. Dr. Osama M. Khaled Sep 09, 2020 04:11 AM
