Introduction The complexity of the modern world and problems and misunderstandings in international relations resulted in the rise of terrorism, which is considered one of the most topical issues of the modern world. Since the beginning of the 20th century, terrorist attacks have resulted in numerous deaths and devastations. That is why the approach to security has been altered to be able to face modern challenges and to protect people. The creation of the perfect security system became the main task of governmental agencies that should monitor the activity of groups that might pose a security issue to the existing world order. Besides, because crowded places often are the main aim of these attacks, security systems, first of all, try to guarantee their protection. Airports could be considered areas of this sort and their protection is very important. The majority of modern airports have unique systems that are implemented to avoid complications and emergent situations. However, they are still not perfect because there are human factors that impact their functioning and condition the appearance of numerous failures. For this reason, the investigation of human factors and understanding the main reasons that conditioned their appearance might increase the safety and security of airports and workplaces. Human factors definition Human factors could be defined as the study of how individuals might behave physically and psychologically in different environments (Harris 2002). The fact is that significant differences that exist among people condition the way they respond to different stressors and act under the emergent conditions. That is why companies have Human factors departments that investigate the given aspects and provide the data needed to create the approaches that might mitigate the possible negative aftermaths of unexpected human actions. Importance Human factors are also extremely important for airport security because they determine the level of the efficiency of its security system (Price 2013). Numerous factors determine the performance of human operators at airport security checkpoints and other important posts. Besides, the mood of a person who performs his/her duties is one of the key aspects that should be considered when trying to predict any possible complications and avoid their appearance. Numerous investigations show that in case a person is disappointed, he/she suffers from the lack of attention, problems with concentration, and pretermission of duties. In this regard, the study of human factors might contribute to improved comprehension of the importance of this aspect and the impact it might have on the organisation of security in airports. Additionally, the error probability also comes from the disregard of human factors. It could increase if an employee is not provided with appropriate conditions or his/her basic needs are ignored. Modern approach Therefore, when speaking about human factors, it is also necessary to admit that their list is constantly being extended because of the appearance of new aspects that impact workers performance. In recent years, new technologies have been introduced to alter the situation in the existing sphere and attain success in the provision of security service
