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.

How should aviation organisations treat information security risks under EASA Part-IS? This article explains how unacceptable cyber risks should be reduced, documented, and managed in practice under IS.I.OR.210. Using a realistic flight operations example, it shows how aviation organisations move from risk identification to effective risk treatment while protecting aviation safety.

Assessing information security risks under EASA Part-IS requires more than technical analysis. It demands a structured, safety-focused approach that identifies how compromised information could affect safe operations. Using a practical CAMO maintenance data scenario, this article breaks down how to evaluate impact, reason through likelihood, derive risk, and ensure assessments are aligned with aviation safety principles.

Information security risk assessment under EASA Part-IS transforms information security from a technical concern into a core aviation safety function. By identifying threat scenarios, assessing safety impact, and evaluating likelihood, organisations can understand where digital risks may affect safe operations and ensure protective measures are focused where they matter most.
