The findings from security audits are considered as one of three inputs in the operational security management process. While one can probably assume this image is not an example of an unwelcome physical security breach of an A380 cockpit, IT security is a new factor in the design of such 21st century aircraft. reliability of the aircraft. A similar observation can be made for the security of IT systems. Due to the complexity of software and economic constraints, it is impossible to ship software without bugs. In fact, the complexity of the software systems built today virtually guarantees the existence of security vulnerabilities. So while software usually is not susceptible to corrosion or material fatigue, software that was considered secure can become insecure as time goes by, due to the discovery of vulnerabilities that were already present but unknown when the software was delivered. Furthermore, the effectiveness of

some technical security measures decreases (e.g., actuality of anti-virus signature or strength of cryptographic algorithms) or even ceases (e.g., certificate expiration) over time if updates are not provided on a regular basis. While the notion of maintenance is well established in the aviation industry, the necessity of also having to maintain the security level of aircraft IT systems is not. That said, such a necessity is well established in the IT security industry. Security disciplines like security audits, vulnerability management, log analysis, and incident management have become an integral part of every IT organization to monitor the security level and respond to a decrease to ensure the operation of business processes. However, these principles and associated activities that are often grouped under the term “Operational Security Management” cannot be directly applied to an aircraft environment. Considerable challenges are encountered when implementing an operational security management process for a fleet of aircraft that is constantly exposed to security threats, continuously moving on a global scale with limited networking capabilities, and for which stringent rules have to be followed to modify the software or configuration. For clarity, a security event is any information that may have
