Why Enhancing Airport Cybersecurity is Vital for Aviation Resilience

Airports serve as critical connectivity hubs, managing massive volumes of sensitive data, while guaranteeing smooth operations for millions of passengers worldwide. However, as airport infrastructure becomes more digitally integrated, cybersecurity has become a major concern. Recent studies have revealed weaknesses throughout airport systems, necessitating a proactive approach to increasing resilience. Given that, airports are adapting and innovating in security strategies.

Cyber-attacks in the aviation industry surged by 131% from 2022 to 2023, with airspace users being the primary targets. These security breaches pose significant financial and reputational risks for the industry. Airports handle massive amounts of passenger and operational data, ranging from personal information to payment details, making them lucrative targets for fraudsters.

Furthermore, as important national infrastructure, security breaches can cause significant disruptions and economic losses. Their reliance on networked systems, particularly Industrial Internet of Things (IoT) devices, broadens their attack surface by exposing critical systems to possible attacks.

In today's interconnected world, airports are rapidly becoming targets for cyberattacks, emphasising the crucial necessity for strong cybersecurity measures. Real-world situations have exposed weaknesses in airport systems, with ransomware attacks and phishing schemes often targeting airport personnel and infrastructure.

These incidents serve as vivid reminders of how modest security breaches can swiftly develop into severe disruptions, compromising operations and passenger safety. The following are some cybersecurity events that have affected airports worldwide, demonstrating the critical need for improved security protocols.

2015 | Distributed Denial-of-Service (DDoS) attack strands 1,400 at Warsaw Airport

In June 2015, Polish airline LOT was subjected to a DDoS hack at Warsaw Airport, which disrupted its computer systems and grounded a portion of its aircraft. The attack stranded 1,400 travellers, cancelled 10 flights, and delayed 15 more.

2016 & 2017 | Boryspil Airport in Kyiv targeted twice by cyberattacks

In 2016, Ukraine experienced cyberattacks on key infrastructure, including Kyiv's Boryspil International Airport, where the BlackEnergy malware was detected but successfully controlled by CERT-UA. A year later, in 2017, Ukraine was hit by another wave of attacks, this time utilising GoldenEye ransomware, which disabled some IT systems at Kyiv Airport and affected infrastructures in numerous nations.

2017 | Heathrow Airport suffers confidential data leak

In 2017, Heathrow Airport was chastised for a serious data breach when an employee misplaced an unencrypted, password-free USB stick holding over 1,000 confidential files. The files contained sensitive passenger information, government officials' travel routes, and airport security details. The USB was discovered and disclosed to the media before being returned to the airport. Heathrow was fined €140,000 for not complying with data protection requirements.

 2020 | San Francisco Airport websites hacked

In March 2020, San Francisco International Airport's employee and partner login portals were hacked with malicious code to steal usernames and passwords. While the number of affected accounts remains unknown, the airport quickly responded by resetting all passwords for employees and customers as a precaution.

2020 | Prague Airport foils multiple cyberattack attempts

In April 2020, Prague's Vaclav Havel Airport and two Czech hospitals faced cyberattack attempts involving malware intended to damage or destroy systems. The airport's IT teams detected the threat early during the attackers' exploratory phase, allowing them to respond swiftly and prevent harm.

2021 | Airport Industry IT supplier hit by cyberattack

In March 2021, SITA, a software provider for the airport business, was hit by a cyberattack that targeted servers containing airline customer data. While the complete damage is unknown, Air India later stated that the breach resulted in the data theft of  4.5 million of passengers, revealing potentially serious consequences for SITA's clients.

Airports encounter a wide range of cyber threats, including but not limited to:

• Ransomware attacks: Cybercriminals frequently attack critical systems, encrypting them and halting operations until a ransom is paid.
• Social engineering: Techniques such as phishing emails are used to trick employees into disclosing sensitive information.
• Internal vulnerabilities: Weak Bring Your Own Device (BYOD) regulations and obsolete systems provide opportunities for unauthorised access.
• Breaches in digital payment systems: Travellers' personal data and payment information are in danger, which may result in regulatory action and financial penalties.

These challenges underline the need for airport cybersecurity policies, which should provide protection against both internal and external dangers.

To address these challenges, airports need to adopt a comprehensive and strategic approach.

1. Zero trust security – Assures that no system, user, or device is implicitly trusted. Microsegmentation isolates vital resources, preventing lateral movement in the case of a breach. This method is critical for safeguarding networked infrastructure, such as IoT systems and legacy equipment.
2. Proactive monitoring – Real-time monitoring is critical for discovering anomalies and responding to threats before they escalate. Advanced monitoring solutions use analytics and machine learning to detect suspicious behaviour as it occurs. Also, most cyberattacks are based on weaknesses found in outdated systems. Performing timely updates and implementing security patches ensures that known exploits cannot be utilised to attack systems.
3. Securing third-party access - Airports collaborate with several third-party vendors and contractors, many of whom need access to sensitive systems. Establishing stringent processes and frequently vetting these external entities can help minimise supply chain risks. 

Risk mitigation necessitates a well-balanced approach that incorporates both technology and organisational policies. This method protects sensitive data and prepares the organisation to deal with threats. Companies may efficiently control risks and keep their information assets secure by combining technological solutions with solid organisational practices.

Technical safeguards

• Use Intrusion Detection Systems (IDS) to detect and neutralise threats.
• To increase security in high-privilege accounts, use multi-factor authentication and biometrics.
• To safeguard sensitive information, use robust encryption across networks and in storage.

Organisational practices

• Employees should be trained to recognise and report phishing and other forms of social engineering.
• Conduct frequent cybersecurity awareness programmes at all levels of the organisation.
• Provide IT and security teams with role-specific training to enhance their response readiness.

Cybersecurity is not an option, but rather a requirement for the aviation business. Airports must take proactive, multi-layered ways to safeguard their systems, data, and, most crucially, the trust of their passengers. The aviation industry can create an infrastructure ready to address growing threats by utilising innovative technologies, organisational processes, and continual monitoring.

Now is the moment to act. Begin safeguarding vital systems and prioritising cyber resilience to provide the safety and dependability that passengers expect and deserve.
