Strengthen aviation cybersecurity and meet regulatory requirements with structured EASA Part-IS compliance support.
The aviation sector is increasingly dependent on digital systems. Aircraft operations, maintenance platforms, airport infrastructure, operational communications and air traffic services all rely on interconnected information systems.
As this digital dependency grows, so does the exposure to cyber threats. To address this risk, the European Union Aviation Safety Agency (EASA) introduced Part-IS, a regulatory framework designed to strengthen cybersecurity across the European aviation ecosystem.
Part-IS requires aviation organisations to implement structured information security management practices to protect aviation systems and operational data.
Maor Compliance supports aviation organisations in understanding, implementing and maintaining compliance with EASA Part-IS requirements. Our services focus on building practical cybersecurity frameworks that meet regulatory expectations while integrating with existing aviation management systems.
Part-IS is the Information Security regulatory framework introduced by EASA to strengthen cybersecurity within the aviation sector.
The framework was introduced through:
Commission Delegated Regulation (EU) 2022/1645
Commission Implementing Regulation (EU) 2023/203
Together, these regulations establish mandatory cybersecurity requirements for organisations operating under European aviation approvals.
Identify and manage cybersecurity risks
Protect aviation information systems
Monitor security threats and vulnerabilities
Detect and report cybersecurity incidents
Manage cybersecurity risks from suppliers and service providers
Integrate cybersecurity governance into existing aviation management systems
In practice, the regulation introduces a formal Information Security Management System (ISMS) within aviation organisations, ensuring cybersecurity is managed in a structured, documented and auditable manner.
The overall objective is to strengthen the resilience of aviation systems and reduce the risk of cyber incidents affecting aviation safety and operational continuity.
Modern aviation operations rely heavily on digital infrastructure.
Aircraft operations, maintenance systems, air traffic management platforms, passenger services and airport operations all depend on secure and reliable information systems.
Cyber incidents affecting these systems could impact:
Aircraft operational systems
Maintenance and airworthiness management
Air navigation and traffic management services
Airport infrastructure and operational systems
Operational communications between aviation stakeholders
Passenger information and booking systems
Part-IS was introduced to ensure aviation organisations implement structured cybersecurity governance capable of protecting these critical systems.
The regulation builds on existing aviation safety management principles by introducing cybersecurity oversight that integrates with operational and safety management structures.
Part-IS applies to a broad range of organisations operating under EASA regulatory approvals.
These typically include:
Commercial airlines and aviation operators conducting passenger or cargo operations.
Maintenance organisations approved under Part-145.
Organisations responsible for managing the continuing airworthiness of aircraft.
Companies involved in aircraft or aviation component design under EASA approvals.
Manufacturers producing aircraft parts, systems or aviation components.
Organisations responsible for airport management and operations.
Entities responsible for air traffic management and navigation services.
Approved training organisations operating under EASA regulatory frameworks.
Part-IS may also apply to other aviation organisations depending on the scope of their regulatory approvals.
Part-IS introduces structured cybersecurity governance, operational processes and monitoring capabilities.
Organisations must implement an Information Security Management System to manage cybersecurity risks affecting aviation systems.
The ISMS should include:
Information security policies and procedures
Defined security roles and responsibilities
Governance structures for cybersecurity oversight
Monitoring and continual improvement of security controls
Many organisations align their implementation with recognised standards such as ISO/IEC 27001, which provides a well-established framework for managing information security.
Organisations must carry out structured cybersecurity risk assessments to identify risks affecting aviation systems and operational infrastructure.
Risk assessments should consider:
Potential cyber threats
Vulnerabilities within IT and operational systems
Operational and safety impacts
Likelihood and severity of potential incidents
Appropriate controls must then be implemented to reduce identified risks to acceptable levels.
Part-IS requires organisations to monitor aviation information systems to detect potential security threats.
Monitoring activities may include:
Network monitoring
Log collection and analysis
Vulnerability scanning
Security event monitoring
Threat intelligence monitoring
Continuous monitoring enables organisations to identify and respond to cyber threats at an early stage.
Organisations must establish procedures to detect, manage and report cybersecurity incidents.
These processes should ensure:
Timely identification of security incidents
Escalation to responsible personnel
Reporting to aviation authorities when required
Investigation and remediation of incidents
Clear incident management processes are essential to maintaining operational resilience.
Many aviation organisations rely on external suppliers, cloud services and IT providers.
Part-IS requires organisations to manage cybersecurity risks associated with third-party services.
This typically includes:
Supplier cybersecurity risk assessments
Contractual security requirements
Oversight of outsourced IT services
Monitoring supplier security performance
Effective supplier risk management is an important component of aviation cybersecurity governance.
The Part-IS regulatory framework was introduced between 2022 and 2023 through two EU regulations.
16 October 2025 — Compliance with Delegated Regulation (EU) 2022/1645
22 February 2026 — Implementing Regulation (EU) 2023/203 becomes applicable
National Aviation Authorities will assess compliance as part of their oversight and certification activities.
Part-IS aligns closely with widely recognised cybersecurity and information security frameworks.
Many aviation organisations implement controls based on:
ISO/IEC 27001
NIST Cybersecurity Framework
EU NIS2 Directive
While these frameworks are not mandatory under Part-IS, they provide a structured approach that supports implementation of many required security controls.

Part-IS is the aviation cybersecurity regulatory framework introduced by EASA requiring aviation organisations to implement structured information security management practices.
ISO/IEC 27001 is not mandatory for Part-IS compliance. However, many organisations use it as a supporting framework for implementing an information security management system.
Oversight is primarily carried out by National Aviation Authorities within EU member states. EASA provides the regulatory framework and supervisory guidance.
Key milestones include:
16 October 2025 — Compliance with Delegated Regulation (EU) 2022/1645
22 February 2026 — Implementing Regulation (EU) 2023/203 becomes applicable
Organisations should ensure their cybersecurity governance and operational processes are aligned with these deadlines.
Preparing for aviation cybersecurity compliance can be complex, particularly for organisations operating across multiple systems and suppliers.
Maor Compliance supports aviation organisations in implementing structured cybersecurity frameworks aligned with regulatory expectations.
