Be prepared and protected to cope with attacks or avoid victimization、 so that the protected object is in a safe state without danger、 infringement、 or accidents. Obviously、 security is the purpose、 prevention is the means、 and achieving or achieving the purpose of security through preventive means is the basic connotation of security prevention. The so-called safety refers to no danger、 no harm、 no accidents、 etc; The so-called prevention refers to preparedness and vigilance、 while preparedness refers to being prepared to deal with danger or avoid harm、 and vigilance refers to being prepared not to harm others and protecting oneself. Public security means that people's property and personal safety can be guaranteed in a certain environment. Security prevention refers to the use of measures or means to prevent the occurrence of certain hazards under the premise of safety、 or to be prepared to respond to hazards. The concept of security in Chinese has two interpretations in English: Safety and Security. The modern advanced English Chinese bilingual dictionary published by Oxford University provides the main interpretation of the word "Safety" as follows: safety、 safety、 security、 safety (lock)、 safety (box)、 etc; The main interpretation of the term "Security" is: security、 no danger、 no worry、 etc.、 providing safe things to exempt from danger or worry、 such as collateral、 collateral、 security (police)、 security (troops)、 etc. In fact、 the security referred to in Chinese is a broad sense of security、 which includes two meanings: one refers to the security of natural or quasi natural attributes、 which corresponds to Safety in English; The second refers to social and humanistic security、 that is、 security with obvious human attributes、 which corresponds to Security. The destruction of the safety of natural or quasi natural attributes is mainly not caused by intentional human participation; Social and humanistic destruction is mainly caused by people's purposeful participation. Therefore、 in a broad sense、 security should include two meanings: Safety and Security、 and the security precautions we often refer to mainly refer to narrow security、 which is commonly referred to as "security" abroad.
