Editorial: Special issue on ARES 2022

In the rapidly evolving landscape of technology, modern society critically relies on a multitude of complex and sophisticated systems. These technological solutions play an indispensable role in various aspects of our daily lives, from communication and transportation to healthcare and entertainment. Given their pervasive nature, it is crucial to explore research areas related to the availability, reliability, and security of these systems. The objective of this special issue is thus to collect innovative research contributions that tackle different open challenges related to the availability, reliability, and security of modern systems. In particular, this special issue was open to the authors of papers accepted at the 17th International Conference on Availability, Reliability, and Security (ARES 2022), which was held at the University of Vienna in Vienna, Austria. Since 2005, ARES has served as an important platform to exchange, discuss, and transfer knowledge related to various aspects of dependability. The 2022 edition has seen contributions tackling several important research topics, including: privacy, cloud security, web security, secure software, and malware detection, network and hardware security, awareness and incident response, threat intelligence and intrusion detection, cryptography, and authentication.
