What You'll Learn
Perimeter security breaches
An airport security breach occurs when an individual or group bypasses security measures, gaining access to restricted areas. Security breaches can occur due to human error, technological failures, or intentional malicious acts. Perimeter security breaches refer specifically to unauthorised access or attempts to access the airport's outer boundaries, which often include chain-link fences, security cameras, patrols, and access control points.
Another method of perimeter breach is by climbing over perimeter fences. This type of breach has been recorded at Ellison Onizuka Kona International Airport in Hawaii, causing a 90-minute shutdown of the security checkpoint and impacting over 1,000 passengers. Other airports with similar perimeter fencing, such as Memphis International Airport, have also experienced breaches where individuals gained access to restricted areas and aircraft.
To mitigate these breaches, airports have implemented various solutions. For example, Phoenix Sky Harbor International Airport installed the StrongArm® M30/M50 barrier arm, which provides an extra layer of security to perimeter gates, hardening them against potential vehicular and individual breaches. Other solutions include the HydraWedge™ SM50, which offers a zero-penetration crash-rated wedge barrier that can be rapidly deployed in emergency situations.
While airports have multiple layers of security, the frequency of perimeter breaches highlights the need for continuous improvement and adaptation to ensure the safety of passengers, staff, and aircraft.

Cyber threats and data breaches
Airports are increasingly vulnerable to cyberattacks due to their reliance on interconnected, complex industrial control systems. Airports handle sensitive data, including passenger information, employee data, biometrics, airline schedules, and cargo manifests. They also have access to customers' personally identifiable information (PII) and payment details. As a result, airports are prime targets for cybercriminals looking to steal data, disrupt operations, or cause financial losses.
A report from ImmuniWeb found that 97 of the world's 100 largest airports have security risks related to vulnerable web and mobile applications, misconfigured public clouds, Dark Web exposure, or code repository leaks. This highlights the need for airports to strengthen their security posture and defend their networks against cyberattacks and data breaches.
Some common types of cyberattacks targeting airports include phishing, malware, ransomware, and denial of service (DoS) attacks. Airports can also fall victim to social engineering attacks, where cybercriminals exploit human psychology to trick individuals into divulging sensitive information or taking action that benefits the attacker. For example, an employee at Heathrow Airport lost a USB stick containing sensitive data, which was later found by a member of the public.
To defend against these threats, airports should implement robust cybersecurity measures and best practices. This includes gaining in-depth visibility into network traffic, implementing zero trust security policies, and using tools like ColorTokens Xshield and Xprotect to identify suspicious connections and lock down critical systems. Airports should also ensure that their partners and contractors have a robust cybersecurity infrastructure to prevent a single weak link from compromising the entire system.
Additionally, airports can benefit from conducting vulnerability assessments, red teaming, and purple teaming exercises to identify weaknesses and improve their security posture. By prioritizing cybersecurity and staying proactive, airports can safeguard their assets, protect sensitive data, and maintain their reputation in the digital age.

Physical security checks
Airport security breaches can have significant and widespread consequences, and airport security attempts to prevent any threats or potentially dangerous situations from arising or entering the country. Physical security checks are an important aspect of airport security. Here are some measures and procedures in place to ensure safe travel:
Passenger Screening:
- Passengers are screened through security checkpoints into "secure", "sterile", or "airside" areas where exit gates to the aircraft are located.
- Screening methods include walk-through metal detectors, full-body scanners, and x-ray machines for carry-on baggage.
- Some airports use millimeter-wave advanced imaging technology to screen passengers for metallic and non-metallic threats, including weapons and explosives, without physical contact.
- Passengers may be randomly selected for physical searches at pre-board screening points.
- Explosive Trace Detection (ETD) is used, with screening officers swabbing carry-on baggage, clothing, shoes, or laptops. Passengers may also be swabbed on their hands, waist, and feet for ETD testing.
Access Control:
- Sensitive areas, such as airport ramps and operational spaces, are restricted to the general public and require special qualifications to enter.
- These areas are monitored through physical access control gates or passive systems that alert security if a restricted area is accessed.
- CCTV and video monitoring of checked baggage facilities are also used, and methods may vary from airport to airport.
Identification and Boarding Pass Verification:
- Passengers are required to present their boarding passes for verification and may need to show photo identification.
- Non-passengers who wish to access secure areas, such as for business meetings, may need to provide at least 24 hours' notice in certain countries.
Prohibited Items:
- Liquids over 100ml, including water, are prohibited due to the risk of liquid explosives.
- Powders in carry-on baggage may require secondary screening and are prohibited if they cannot be identified by security officials.
- Hazardous materials are generally forbidden in both carry-on and checked baggage.
- Certain items, such as blades, may be subject to length restrictions and must be packed in checked baggage for specific destinations.
Sanitation:
- Sanitation practices have become increasingly important in airport security to prevent the spread of respiratory viruses.
- Plastic utensils and glasses are now used in airport food outlets to reduce potential hygiene risks.

Human error
In addition to procedural errors, human error can also involve negligence or carelessness. For instance, an employee at Heathrow Airport lost a USB stick containing sensitive data, including information about the Queen's routes and personal details of airport security staff. This incident led to a fine for Heathrow Airport for failing to secure sensitive data. Similarly, British Airways experienced a data breach where hackers accessed the personal and financial details of 380,000 passengers due to inadequate security measures.
Furthermore, human error can occur when individuals attempt to evade security measures. Since March 2023, there have been at least 300 instances of people trying to bypass parts of airport security. In one case, a woman boarded an American Airlines flight without a boarding pass, sneaking past the ID checkpoint. While she went through security, the breach highlighted the potential for human error in monitoring exit points and preventing unauthorized access.
To mitigate human error, airports are investing in new technologies and updates, such as automated doors and one-way exits, to enhance security and reduce the impact of potential errors. Additionally, improving training and education on security procedures and data protection can help minimize the occurrence and impact of human errors.
