Why it Matters

EASA Part-ISestablishes a unified approach to safeguarding aviation informationsystems against evolving cyber threats while supporting regulatorycompliance.

Key benefits include:

• Strengthen cybersecurity governance

Promote consistent securityleadership by integrating information security into organizationalpolicies, management processes, and oversight structures.

• Enhance regulatory alignment

Enable organizations to meet EUaviation cybersecurity requirements, reducing gaps in compliance andsupporting ongoing regulatory reporting obligations.

• Improve incident detection and response

Facilitate robust monitoring andescalation procedures, allowing faster identification and containmentof cyber incidents impacting aviation operations.

• Protect sensitive operational data

Implement targeted controls thathelp secure flight, passenger, and operational data critical tosafety and business continuity.

• Increase audit and readiness posture

Provide a clear framework fordemonstrating control effectiveness, supporting both internal auditsand external regulatory assessments.

How it Works

EASA Part-ISorganizes information security obligations into regulatoryrequirements and control areas tailored to the aviation sector. Theregulation establishes a risk-based approach covering governance,asset and access management, incident reporting, supply-chainsecurity, and continuity. It outlines lifecycle processes andreporting obligations that operators and suppliers must follow tomeet compliance.

Organizationsimplement EASA Part-IS by conducting risk assessments, mappingsecurity controls to operational assets, and embedding requirementsinto existing safety and security governance frameworks. They appointaccountable roles, deploy monitoring and detection measures, runexercises and audits, and maintain incident response and notificationprocedures to satisfy regulatory reporting and continuous improvementof security practices.

WithinSmartSuite, teams operationalize EASA Part-IS by loading controllibraries and mapping them to a centralized risk register, linkingpolicy governance to evidence collection, and enabling compliancetracking. Automated remediation workflows, audit readinesschecklists, and reporting dashboards support monitoring, documenttrails for audits, and coordinated risk management across programs.

Key Elements

• Information Security Governance Structure

Establishes organizationalresponsibilities, policies, and oversight mechanisms for informationsecurity management within aviation operations.

• Cybersecurity Risk Management Process

Describes procedures foridentifying, assessing, and mitigating risks that may impact aviationinformation systems and services.

• Incident Reporting and Response Protocols

Specifies mandatory steps forreporting, handling, and resolving cybersecurity incidents affectingaviation safety and operations.

• Operational Security Control Areas

Organizes protective measurescovering access management, system security, and data integrityrelevant to aviation-specific environments.

• Vulnerability and Threat Assessment Practices

Outlines structured methods foridentifying, evaluating, and addressing vulnerabilities and emergingthreats.

• Compliance and Monitoring Processes

Defines procedures for ongoingevaluation, audit, and demonstration of adherence to regulatoryinformation security requirements.

Framework Scope

EASA Part-IS —Information Security Regulation (EU) 2023/203 is adopted by civilaviation carriers, maintenance providers, and airport operators withresponsibility for aviation-related information and operationaltechnology systems. The regulation governs information assetscritical to aviation safety and is implemented to satisfy regulatorymandates, enhance cybersecurity risk management, and supportcompliance oversight and operational resilience.

Framework Objectives

EASA Part-IS —Information Security Regulation (EU) 2023/203 defines key objectivesto improve cybersecurity and resilience in civil aviationorganizations.

Safeguard information assets and systems vital to aviation safety andoperations

Strengthen cybersecurity risk management and governance acrossregulated entities

Enable compliance with regulatory requirements for informationsecurity controls

Enhance operational resilience against cyber threats and emergingattack vectors

Improve detection, reporting, and response to cybersecurity incidents

Promote ongoing data protection and increase audit readiness in theaviation sector EASA Part IS, the EU aviation informationsecurity regulation, maps to and complements frameworks such asISO/IEC 27001, NIS2, and GDPR by aligning control requirements andincident reporting expectations. Aviation organizations implementPart IS for regulatory compliance and certification, tostrengthen security governance, and to operationally improve cyberresilience across fleets and supply chains.

Framework in Context
