Over the past few years, the aviation industry has been challenged as never before due to the global pandemic. However, one of its enduring challenges remains cybersecurity. At the same time, space is emerging as an operational domain, bringing unique cybersecurity considerations for defense organizations. This development provides the occasion for security practitioners throughout the wider aerospace community to work with policymakers and civil society to confront the common challenges of aviation and space and, in so doing, to realize the development of more resilient systems.
The aviation sector remains a prime target for cyberattacks. Airports, airlines, aircraft, subcontractors, and service providers handle massive amounts of personal data, including passport details and credit cards. The growing digitization of airplanes and the growing interconnection of components for navigation and communication systems have only created more touchpoints for cybercriminals to attack. As a result, the number of cyberattacks on the aviation industry has grown significantly.
The global aerospace cybersecurity industry was pegged at $26.3 billion in 2022 and is expected to hit $58.8 billion by 2032, registering a CAGR of 8.4% from 2023 to 2032. – Allied Market Research ReportÂ
Security Challenges in the Aerospace and Aviation Industry
The aerospace and aviation industry faces critical IT security challenges due to systems interconnection, mission-critical infrastructures, and sensitive data. Cyber-attacks on flight controls, navigation, and communications networks pose serious—potentially catastrophic—risks: flights can be disrupted, safety compromised, or aircraft control granted to unauthorized users.
This adds to the supply chain vulnerabilities in the current industry. The global network supporting it is vulnerable to instilling vectors if elements are compromised or bad code is placed during manufacturing or distribution. The industry’s increased connectivity, both on the flight and on the ground, increases the threat surface, and satellite systems add other threats to its security.
Compliance with stringent standards is important and critical for safety, security, and efficiency in operations. To this effect, some of the standards it has to comply with include the following:
- Compliance standards
- Supply chain vulnerabilities
- Diverse operation environments
- Legacy systems and compatibility
- Sophisticated threats that are forever on the rise

Steps to Improve Cybersecurity in Aerospace and Aviation
1. Assess the Origin of Threats
Cyber threats can come from a range of sources, from user behavior to design flaws and coding errors. Design flaws, such as inadequate user authentication and coding errors, such as injection vulnerabilities, can create potential points of attack. Due to the complexity of the aerospace and defense procurement process, a vulnerability can arise at any point in the supply chain. A commitment to seeing all sources of software checked for vulnerabilities is necessary:
- Legacy Code: Legacy code poses cybersecurity risks because it was written before testing for cybersecurity vulnerabilities, and it no longer receives technical support updates.
- New Development: While new projects are optimal in applying the latest security techniques, budgetary and release pressures generally prevent this.
- Open Source Software (OSS): OSS is very widely used, but its accessibility allows malicious actors to compromise it.
- Commercial-Off-the-Shelf (COTS): If not required to meet strict requirements and tested, COTS software could potentially introduce an undiscovered vulnerability.
2. Make Sure Cybersecurity is a Part of Development Strategy
As noted in the SWAP Report, include cybersecurity strategies in development and business objectives by using adaptive processes that address emerging threats and market dynamics. Invest in training and tools that reduce developer effort and lower the probability of producing a vulnerability. Developers must have targeted cybersecurity budgets for training and secure coding practice.
3. Simplify Cybersecurity Testing with Standards
Adopting common guidelines to check code for vulnerabilities is important. Leveraging known aerospace and defense cybersecurity standards leads to:
- CWE: The Common Weakness Enumeration (CWE) Top 25 lists the most critical weaknesses attackers use.
- DISA STIG: The Defense Information Systems Agency Security Technical Implementation Guide offers security management guidelines.
- OWASP: The Open Web Application Security Project Top 10 lists the top critical security risks to applications.
- MISRA and MISRA C:2012: These guidelines assure proper and secure coding practices for C and C++.
4. Reduce the Impact on Development through Automation
This should not add to developers’ workloads. Automation techniques, especially Static Analysis (SA), are keeping pace with evolving threats and codebases. Automating compliance with cybersecurity standards inherently increases accuracy and consistency. For instance, tools such as Klocwork by Perforce analyze source code and identify vulnerabilities and gaps in compliance, thus reducing associated risks for secure release.
5. Secure the Software Supply Chain
Securing the software supply chain is equally vital, as the Executive Order on Improving the Nation’s Cybersecurity further underscores. Supply chain attacks will increase, given the rise in the use of diverse technologies and less dependence on large software providers. Potentially risky third parties include suppliers, vendors, open-source projects, and other connected systems. Proving the integrity and security of the software supply chain is important for robust cybersecurity in aerospace and aviation.
Key Principles for Ensuring Cyber and Operational Resilience
Gain Visibility into CPS
Whenever evaluating a Cyber-Physical System (CPS) security solution, one must ensure that visibility is in the solution of the Operational Technology (OT) environment. Visibility is the foundation of cybersecurity, for organizations cannot protect what they cannot see or understand. This is a significant challenge because the protocols are frequently proprietary, and Extended Internet of Things (XIoT) devices are typically incompatible with general security tools.
Aviation environments host a mixture of new and legacy devices that exhibit dissimilar behaviors, making device identification difficult. The uniqueness of each XIoT environment further complicates asset discovery. Therefore, CPS security solutions must provide flexible, multiple discovery methods that are customizable to the specific need.
Integrate Existing IT Tools and Workflows with OT
In most cases, CPS follow the use of proprietary protocols and legacy systems, and as such, they are incompatible with traditional IT solutions. However, organizations should not add to their growing technology stack but instead look for CPS security solutions that integrate existing IT tools and workflows with OT. This unlocks those siloed risk blind spots without risking operations and promotes visibility across siloed teams.
Extend IT Security Controls and Governance to the XIoT Environment
XIoT environment largely misses several common cybersecurity controls and consistent governance. Legacy systems were designed for functionality and reliability and not security since they were not originally connected to the internet. The fusion of these systems into IT networks due to digital transformation and remote work has presented a myriad of security concerns. With no dedicated security teams or solutions with a core focus on OT systems, there is inconsistent governance and control.
Aviation organizations need to consider CPS security vendors that provide visibility into CPS, embed IT tools and workflows, and extend IT controls into the XIoT environment. The consolidation of security governance is critical to the realization of cyber and operational resilience.
