Not every vulnerability needs fixing. But every one of them needs a decision. Under IS.I.OR.220, the act of logging a weakness and setting it aside is itself a risk position — and it needs to be a deliberate one. This article covers how vulnerability response should actually work: CVSS scoring, contextual risk assessment, and when treatment becomes mandatory under EASA Part-IS.

Incident and vulnerability detection under EASA Part-IS begins with the collection and analysis of information security events. This article explains how monitoring, internal reporting, external intelligence, and auditing work together to identify abnormal activity, detect incidents early, and uncover vulnerabilities that may impact aviation safety and operational integrity.

Understanding the distinction between vulnerabilities and incidents is critical for effective EASA Part-IS compliance. This article provides a clear, practical breakdown of IS.I.OR.220, helping organisations correctly assess, manage, and respond to each. It offers structured guidance to strengthen your ISMS, support informed decision-making, and ensure a proactive, risk-based approach to aviation information security.
