In last period, the technology development has experienced accelerated and extreme growth resulting in many concepts such as: blockchain, quantum technology, Robotic Process Automation (RPA), Artificial Intelligence (AI) and Machine Learning (ML), Internet of Things (IoT), edge computing, Virtual Reality (VR) and Augmented Reality (AR), and 5th (5G) and 6th (6G) generation networks. This trend is increased by the SARS-CoV-2 pandemic, given that the technology enabled continuance of affairs. In parallel, the threats and attacks on cyber security have dramatically increased as well, causing many losses of all kinds. These two trends need to be treated combined for the purpose of timely and proper addressing and solving of security issues and challenges in the context of future technologies. Therefore, this work contributes by providing a brief overview of cyber security perspective, i.e. challenges and issues for top future technologies. The conducted analysis has shown that security issues for future technologies are numerous and need to be treated in systematic and organized manner during the design of technologies and products in order to minimize the risk and damage and maximize the utilization and benefit.
