Japan Airlines Cyberattack: Could such an attack have been prevented?
The answer lies in a technology that has stood the test of time—Mainframes.

Japan Airlines (JAL) fell victim to a crippling cyberattack that forced the suspension of ticket sales and disrupted services. It may have been the victim of a distributed denial-of-service says JAL, or DDoS attack, in which networks are overwhelmed by massive amounts of data from multiple sources over a short period. This incident is yet another reminder of the vulnerabilities plaguing modern IT infrastructures. While many organizations have embraced cloud-based systems for their agility and scalability, the inherent security risks associated with these platforms often go overlooked.
Why Mainframes Are Less Prone to Cyberattacks
Mainframes, such as IBM's Z Systems, are renowned for their security, reliability, and resilience. Unlike modern cloud and distributed systems, mainframes are engineered to provide an ironclad foundation for critical applications and data processing. Here’s why mainframes are significantly less vulnerable to cyber threats:
Integrated Security Framework
Mainframes come with advanced, built-in security features, including encryption, multifactor authentication, and secure boot mechanisms. These systems are designed with security as a core component, not an afterthought.
Unmatched Workload Isolation
In distributed environments, a breach in one application can potentially compromise the entire system. Mainframes, however, isolate workloads at the hardware level, ensuring that each process operates independently and securely.
Proven Reliability
Mainframes have a legacy of uninterrupted service spanning decades. Their architecture prevents unauthorized access and tampering, making them the preferred choice for industries like banking, aviation, and government.
Comprehensive Monitoring and Auditing
Every transaction on a mainframe is logged, monitored, and audited in real time. This level of visibility makes it easier to detect and respond to suspicious activities before they escalate.
Disaster Recovery (DR) Excellence
Mainframes are built to recover quickly from disruptions. Their superior DR capabilities ensure minimal downtime, even during severe cyber incidents.
The Risks of Moving Away from Mainframes
As businesses race to adopt cloud-based solutions, many have retired their legacy mainframe systems, prioritizing cost savings and scalability over security. However, this shift often leads to:
Increased Exposure to Cyber Threats: Cloud systems are attractive targets for hackers due to their centralized nature and shared infrastructure.
Configuration Errors: Human errors in managing cloud systems often create vulnerabilities.
Limited Control: Relying on third-party providers can dilute an organization’s control over its data and security protocols.
The JAL cyberattack exemplifies the consequences of underestimating these risks. Had their systems been running on mainframes, the outcome might have been different.
The Case for Mainframes in Modern IT
While cloud computing has its merits, organizations should reconsider abandoning mainframes altogether. A hybrid IT model that integrates the reliability of mainframes with the flexibility of the cloud can provide the best of both worlds.
Mainframes remain indispensable for industries that prioritize security, scalability, and uptime. Airlines, banks, and healthcare providers—sectors that manage sensitive customer data and require 24/7 availability—stand to benefit immensely from mainframe technology.
Learn from the Past to Secure the Future
The cyberattack on Japan Airlines is a stark reminder of the importance of robust cybersecurity measures. As organizations chart their digital transformation journeys, they must prioritize security over convenience.
Mainframes, with their proven track record and unmatched resilience, offer a level of protection that modern systems struggle to replicate. For companies like JAL and others, investing in mainframe technology isn’t just a nod to the past—it’s a strategic move to secure the future.
Let this incident serve as a wake-up call: Cutting-edge doesn’t always mean better. Sometimes, the best way forward is to return to the foundations that have consistently stood strong against the test of time.
