Making Air Travel Security Screening Faster and More Secure: Potential Improvements to Airport Security

Team AckoJan 17, 2024

Over the last decade, airport security processes have grown in importance, particularly in India as we have witnessed terror attacks, attempted hijackings, and other security threats. As a result, the process of screening passengers has become increasingly important and involves the use of advanced technology and processes. In order to ensure fast, secure, and efficient security screening, airports must constantly review and update their processes and screen their passengers in accordance with the latest rules. This article will provide an overview of the top 10 processes of airport security screening and potential improvements for airports in India.




1. Pre-Flight Passenger Screening

Pre-flight passenger screening is the most crucial process in any airport. Security staff must have the skills to identify any suspicious behavior or activities of passengers. At entry points, personnel must check the identification documents of all passengers and check them against the document required for entry. This process also entails performing baggage searches and pat-downs, as well as metal detection, if required. If a passenger is considered suspicious, relevant authorities must be alerted.

2. Carry-on Luggage Screening

Carry-on luggage screening is also part of pre-flight security, where airport security personnel must visually inspect all carry-on items, including laptops, mobile phones, and other personal belongings. Airport staff may also use magnetometer gates, RFID scanners, and X-ray machines to scan bags for any suspicious items. These screenings can be conducted at the passenger check-in point, security checkpoints, boarding gates, boarding lounges, and other areas.

3. Chemical & Explosive Detection

Given the threat of chemical and explosive weapons, airport security personnel must conduct special screenings to detect any suspicious items that may be in the luggage or on a person’s person. This can be achieved through the use of bomb-sniffing dogs, chemical trace detectors, and X-ray machines. Airport staff must also be constantly aware of any changes in technology or processes that may increase the effectiveness of chemical and explosive detection.

4. Passenger Behavior Evaluation

A less tangible, but equally important process of screening passengers involves the observation and recording of passengers’ behaviors. Security personnel must be aware of any suspicious behavior, such as excessive nervousness, sweating, avoiding eye contact, and other suspicious activities. Staff should be trained to know how to properly assess and properly handle such situations.

5. Use of Facial Recognition Technology

With the advancement of technology, more airports are now utilizing facial recognition technology to enhance the security screening process. This involves the use of cameras powered by facial recognition software to match the facial features of passengers to data stored in databases or obtained from immigration or law enforcement records. This helps in ensuring a streamlined and efficient screening.

6. Cybersecurity

Cyber security is an important aspect of airport security, as airports collect and store large amounts of data regarding passengers and personnel. Cyber threats such as data breaches, ransomware attacks, and malicious software can be damaging and difficult to detect and address. Airports must ensure that their IT infrastructure is protected with the latest security protections and that they have the appropriate cyber security protocols in place.

7. Background Checks

Background checks are an essential part of airport security. All personnel who handle sensitive information must be subject to background checks, particularly those who have access to secure areas. Airport staff must also be trained in proper access control protocols and procedures for the entry of vehicles and personnel in absolutely secure zones.

8. Cargo Screening

While passenger screenings are conducted on a regular basis, cargo and freight being shipped on flights must also be monitored for any suspicious items. For this reason, all cargo shipments must be screened by security personnel. This process entails manually inspecting the cargo and using X-ray machines and other technologies to scan for any potential threats.

9. Closed-Circuit Television

Closed-circuit television (CCTV) is an important security tool that enables airport personnel to monitor potential threats or suspicious activities. This technology is also often used to monitor the movement of vehicles, personnel, and baggage in and around the airport. The use of CCTV allows airports to watch and react to any suspicious activity in an efficient manner.

10. Use of Biometrics

Biometrics, such as fingerprint and facial recognition, is increasingly being used by airports for security purposes. This advanced technology helps in reducing the time taken for scanning and verification of passengers, as biometrics requires only a few seconds to process the information. Airports are now incorporating this technology into their security processes for more efficient screening.


Airport security screening is a crucial process that requires the use of advanced technologies and adherence to processes. In India, it is essential that airports take the necessary steps to update their security processes and ensure that they consistently stay ahead of any potential threats or suspicious activities. This list of the top 10 processes of airport security screening and potential improvements serves as a good guide for airports in India.
