What the UAE aviation FZ1073 incident can teach Hungary about resilient critical systems

The security incident aboard flydubai flight FZ1073 on 30 September is still under investigation, and that fact should discipline every serious discussion of it. UAE authorities have confirmed that the flight from Dubai to Tel Aviv experienced a security incident, was diverted and landed safely at Tabuk Airport in Saudi Arabia. The UAE Attorney-General has formed a specialised investigation team to establish the circumstances and motives, while officials have warned against speculation. I agree with that caution. We do not need to guess the motive to recognise the security question the incident has placed in front of us. FZ1073 incident raises security lessons for Hungary:

Hungary’s manufacturing, logistics and transport networks make this question relevant far beyond aviation. The UAE and Hungary have both attracted investment that depends on reliable infrastructure and increasingly automated operations. As those systems become more connected, organisations will spend heavily to keep unauthorised users out. They should devote equal attention to what legitimate users can do after they are in.

For decades, security has become very good at asking who is allowed through the door. We verify identity, role, clearance and permission. I have spent years in security environments where those controls matter every day. Yet authorisation answers only the first question. The harder question begins after entry: if circumstances or behaviour change, can the system recognise that change and intervene without waiting for the consequences to prove that trust should have been reconsidered?

This is not an argument for treating trusted professionals as suspects. Complex systems cannot function without trust. Pilots, engineers, controllers, operators and administrators need real authority to do their jobs. My concern is different: organisations sometimes confuse justified trust with permanent trust. A badge, clearance or professional title can explain why someone was admitted yesterday; it cannot guarantee the safety of every action tomorrow.

That is why I distinguish between access control and authority control. Access control decides who may enter. Authority control asks what an authorised person can do after entry, how critical power is distributed, what abnormal conditions trigger challenge, and how quickly others can limit or redirect authority if the risk picture changes. The second problem is harder because it sits inside the trusted system rather than outside it.

For Hungary, this is also a competitiveness issue. Investors do not only ask whether a facility is protected; they care whether disruption can be contained and operations restored. Authority that is too concentrated can turn one internal failure into a business-continuity event. A resilient institution therefore gives trusted people enough power to work while ensuring that critical actions remain visible, challengeable and reversible.

The response should not be another layer of suspicion for its own sake. Better design is more useful: clear escalation routes, meaningful redundancy around critical actions, a culture in which questioning an abnormal action is not treated as disloyalty, and emergency procedures that are designed before the emergency. Human courage will always matter, but a mature security system should not make last-minute heroism its final control.

FZ1073 also reminds us that resilience crosses borders. What began aboard a UAE-registered aircraft required a safe operational response in Saudi Arabia, and the UAE Ministry of Foreign Affairs later expressed appreciation to the Saudi authorities for their cooperation and handling of the incident. A crisis rarely respects the organisational or national boundary where it begins. The next system in the chain may suddenly become part of the solution.

The investigation should determine the specific lessons for aviation. The broader lesson is already worth asking in every high-consequence sector: are we protecting only the boundary, or are we also protecting what happens after legitimate access has been granted? The door still matters. So do the clearance and the background check. But modern security must be equally prepared for the question that begins one second later: now that the person is inside, how does the system remain safe?
