Ransomware-campaigns such as WannaCry and (Not)Petya highlighted the global and multidimensional nature of vulnerabilities and showed how substantial the impact of these could be for many aspects of the daily life. Vulnerability disclosure is a valuable instrument to report and solve these vulnerabilities to increase the security of information systems and prevent such events from happening. However, EU’s legal landscape for vulnerability disclosure is fragmented, and vulnerability researchers have to deal with legal uncertainty. Therefore, this thesis focuses on how the EU can increase the resilience of its cyber ecosystem through stimulating vulnerability disclosure. The purpose of this study will be to describe the different policy instruments the EU may use to stimulate coordinated vulnerability disclosure and prescribe which ones would be most valuable for increasing the EU’s cyber resilience. Coordinated vulnerability disclosure refers to the approach of disclosing vulnerabilities in the security of information systems in a controlled and responsible manner. This thesis will combine an analysis of primary and secondary sources – using technical and non-technical perspectives to bring these two worlds closer together to develop effective cybersecurity policies. To provide a deeper understanding of how the EU could construct a resilient cyber ecosystem: insight on cybersecurity, the resilience of ecosystems and security governance will be combined. Concluding, it is recommended that the EU uses a mix of regulatory instruments making optimal use of the expertise of the private sector to stimulate coordinated vulnerability disclosure. The outcomes are timely because in September 2017 a new EU Cyberstrategy will be presented.Show less
