Assumptions of CPTED theory immunization in the critical infrastructure of the airport

Terrorist acts are typical threats that provoke a crisis of considerable size not only in the country but also in the countries or regions. Terrorist interest will always be aroused by elements of state infrastructure, which are defined as essential for the daily functioning of people and public administration. Airports serving people and providing fast transport of goods are of particular interest to modern terrorists. Terrorist attacks targeting the airport infrastructure can cause both their destruction and damage, as well as initiate breakdowns that result in not only huge material losses, but significant deaths and damage to a substantial number of people. As a consequence, they may cause insecurity, panic and abandon the use of services guaranteed by carriers and airports. Developing real and effective protection plans, based on the results of research and analysis and good practice - allows for effective protection of a key airport area and, in a crisis situation, to minimize costs resulting from an attack. The Crime Prevention Trough Environmental Design (CPTED) concept of prevention of crime by shaping space focuses on physical space as an important factor influencing criminal behavior. This space is connected in various ways with the criminal act. The theory of shaping safe spaces assumes that criminals make a rational choice of purpose, and their decisions are supported by an analysis of the conditions existing in a given space (risk analysis). Their choice applies to both the places they prefer as the crime scene and the areas they avoid. The aim of the article is to present elements of the CPTED concept, which may be adopted in the protection of airport infrastructure
