Secure communication networks and distributed systems for a resilient society

Given the central role of modern digital technologies, it is crucial that digital infrastructures and information systems be resilient. Yet, communication networks and interconnected IT systems are not always secure nor reliable. They are susceptible to design and implementation flaws, which make them vulnerable to attacks. This briefing paper aims to examine the root causes of this problem and how we could address them. We start by exploring some practical scenarios that demonstrate failures in the construction of secure networks and distributed systems. We then explore technical and non-technical challenges as potential root causes of these failures and conclude with a call to action to address the issues. We find that several stakeholder groups – particularly researchers, developers, decision-makers, and policy-makers – must take action to ensure that networks and distributed systems become more secure and resilient in the future.
