Fundamentally based on collaboration, open-source software (OSS) has particular implications for digital security, in terms of both strengths and limitations. However, these are not sufficiently understood by policy makers. 

Recognising the considerable importance of OSS today, this theme will aim to inform policy makers about OSS security opportunities and challenges and discuss how policy makers can best ensure that cybersecurity policies fully take OSS specificities into account to best reduce digital security risk. 

Across all sectors, supply chains are increasingly relying on increasingly complex cross-border digital ecosystems to support their economic and social activities. All organisations taking part in supply chains are interconnected and therefore, from a digital security standpoint, they are also all interdependent. This means that the security of all partners is aligned with the security of the weakest of them. 

This theme will provide an opportunity for industry, policymakers, and stakeholders from civil society to highlight considerations regarding supply chains and Managed Service Providers and to discuss possible measures, including zero trust, that the international community can take to embed resilience within global supply chains that support economies.

Many countries are developing digital security legislation and regulation, whether to protect critical activities and infrastructure, to enhance the security of products and services, or to improve vulnerability treatment.
