Look at this excerpt from the global ethics of tourism code:
It is the task of the public authorities to provide protection for tourists and visitors and their belongings; they must pay particular attention to the safety of foreign tourists owing to the particular vulnerability they may have;
they should facilitate the introduction of specific means of information, prevention, security, insurance and assistance consistent with their needs. (source)
I do not understand the meaning of prevention in this context? How is it different from security?
