Editorial Sustainable Defence and Security Systems

In an increasingly interconnected world, the sophistication of cyber-attacks is on the rise. Cybersecurity research stands as a pivotal factor in shaping the prosperity of nations. To counter threats to network infrastructure and sensitive data, a multitude of security solutions with varying degrees of efficacy have been proposed. However, these solutions have thus far insufficiently accounted for a critical dimension: sustainability. In this context, sustainability entails the continuous support of processes over time by enhancing the computational requisites, scalability, energy efficiency, and resource utilization of defence and security systems. This special issue endeavors to explore recent strides in model development, innovative methodologies, and insightful observations aimed at enhancing cybersecurity, with a particular emphasis on the sustainability of defence and security systems.
