Using Bowtie Risk Assessment to comply with EASA Part IS


 Core Competency Accelerator

 

 


This training delivers a comprehensive and practical understanding of how to apply Bowtie Risk Assessment to meet IS.I.OR.205 requirements, in particular where cyber-related top events may trigger significant aviation safety consequences. Delegates will learn how to build, validate, and apply Interacting Bowties to support the required “handshake” between the Safety Manager and Information Security Manager - the core mechanism demanded by the revised AMC & GM supporting Part IS.

The course addresses the dual-methodology approach now mandated under EASA Part IS, where Bowtie analysis becomes compulsory for risks capable of affecting aviation safety. Delegates will be equipped to translate threat intelligence, system architecture, and operational realities into barrier-based visual models capable of meeting auditor expectations for barrier effectiveness, independence, and traceability.

WHO IS THE COURSE FOR?


This course is intended for personnel required to demonstrate aligned understanding of Information Security and Aviation Safety interactions under the EASA framework, including:

• Information Security Managers (ISM) and Cybersecurity Specialists
• Safety Managers, SMS Coordinators and Safety Investigators
• Compliance Monitoring Auditors and Quality Professionals
• CAMO, Part-145, Ground Handling and Flight Operations leadership
• Digital systems owners and data custodians responsible for critical operational data
• Accountable Managers seeking assurance of regulatory conformity

WHAT IS THE BENEFIT OF THIS TRAINING - WHAT WILL I LEARN?


By completing this course, participants will:

• Gain a structured competency in Bowtie methodology applied to Information Security
• Understand how to construct Interacting Bowties to satisfy IS.I.OR.205 risk analysis expectations
• Learn to identify Hazard / Top Event / Consequence distinctions to prevent misclassification during audits
• Develop the capability to evaluate barrier performance, not just presence, including escalation factors
• Recognise when Bowtie analysis is mandatory versus when standard risk matrices remain sufficient
• Build the skillset needed to support quantitative comparison between “Achieved Security Likelihood” and “Safety Target Likelihood” required under the new Part-IS model
• Increase organisational readiness for oversight by demonstrating measurable integration of cyber-risk into SMS processes

LEARNING OBJECTIVES


Upon completion of this course, participants will be able to:

• Construct defensible Bowtie diagrams aligned with EASA ED Decisions 2025/013/R–015/R expectations
• Apply the dual-methodology requirement to correctly select when Bowtie analysis is obligatory
• Perform the interacting risk-assessment process (“the translation handshake”) between security and safety
• Identify and define barriers, escalation factors, and barrier effectiveness ratings to support auditability
• Integrate Bowtie outputs into SMS, ISMS and Compliance Monitoring activities
• Support decision-makers in closing risk gaps where Achieved Likelihood > Target Likelihood, as required under Part IS
