LET US HELP YOU!
Aviation in APAC is critical infrastructure. Cybersecurity for aviation operators has to match that level of threat.
THE REALITY
The airline and aviation security landscape in APAC.
Aviation operators in APAC manage some of the most complex cybersecurity environments in any sector. IT and OT systems are deeply interconnected. Passenger services, reservation systems, cargo management, and aircraft maintenance data flow across networks that also interface with safety-critical operational technology. A cyberattack that disrupts operational systems carries consequences that extend well beyond data loss. Regulators in Singapore, Hong Kong, Malaysia, and the Philippines increasingly treat airlines and airports as critical infrastructure operators, with explicit security obligations that reflect that designation.
THE CHALLENGES
The security challenges airline and aviation operators face most often.
IT and OT convergence across operational environments
Airlines and airports operate environments where passenger-facing IT systems connect to operational technology covering ground support, cargo handling, and aircraft maintenance. The IT/OT boundary is the primary attack surface for adversaries targeting aviation operational disruption.
Passenger data at scale
Airlines hold passenger data at a scale that creates significant privacy and breach notification obligations. Frequent flyer databases, payment records, and travel document data are high-value targets across APAC aviation breach scenarios.
Third-party and supply chain risk across the aviation ecosystem
Aviation operators depend on third-party systems for ground handling, maintenance, catering, fuel, and technology. Each vendor relationship is a potential attack vector. Third-party compromise has provided adversaries with access to airline operational networks in multiple documented incidents.
Reservation and ticketing system security
Global distribution systems, passenger name records, and ticketing platforms are shared infrastructure across the aviation industry. Compromise of a shared platform can affect multiple carriers simultaneously.
Regulatory compliance as critical infrastructure
Aviation operators designated as critical infrastructure face explicit security obligations under national frameworks. Each market carries distinct notification timelines, documentation requirements, and security control expectations.
Insider threat across a large and distributed workforce
Airlines operate large, geographically distributed workforces with access to operational and passenger systems. Insider threat, whether malicious or through social engineering, is a consistent finding in aviation security assessments.
REGULATORY CONTEXT
Regulatory context for airline and aviation operators across APAC.
Meeting the security obligations facing aviation operators designated as critical infrastructure is increasingly demanding. Each APAC market carries distinct notification timelines, documentation requirements, and control expectations. Theos practitioners have worked inside the regulatory frameworks governing aviation operators across Singapore, Hong Kong, Malaysia, and the Philippines. That experience shapes how we scope engagements, structure findings, and produce documentation that holds up under examination.
REGULATORY CONTEXT
How Theos delivers security outcomes for airline and aviation operators.
Managed Threat Detection and Response
24/7 monitoring across both IT and OT environments. Detection calibrated to the specific attack patterns targeting APAC aviation operators, including nation-state threat actors with documented interest in aviation critical infrastructure.
Vulnerability Assessment and Penetration Testing
CREST-certified testing that explicitly addresses the IT/OT boundary, passenger systems, reservation platforms, and third-party integrations. Findings documented to the standard critical infrastructure operators require.
Compromise Assessment
Practitioner-led investigation of aviation environments for signs of attacker presence. Recommended following any supply chain event affecting aviation technology vendors or ground handling providers.
Tabletop Exercise
Facilitated incident scenarios that test executive and operational decision-making under realistic aviation disruption pressure. Scenarios include operational system outage, passenger data breach, and ransomware affecting ground operations.
IR Preparedness
Incident Response Plans, Frameworks, and Playbooks built around aviation-specific incident scenarios and the notification obligations of each APAC market where the operator holds a licence.
Red Teaming
Full-scope adversary simulation including physical access scenarios, insider threat vectors, and IT/OT boundary penetration. Tests whether operational teams detect and contain a realistic adversary campaign.
Theos delivers these services to aviation operators across Singapore, Hong Kong, Malaysia, and the Philippines under the Singapore Cybersecurity Act, the Protection of Critical Infrastructure (Computer System) Ordinance (Hong Kong), Malaysia’s Cyber Security Act 2024, and the ICAO cybersecurity framework.
