The Key Theoretical Models for the Safety and Security Ensuring

Problems of safety and security follows the people whole civilization evolution. Nowadays, many kinds of safety or security exist. During the constitution each kind of safety or security, procedure was pragmatic and assigned. Practice overturns theory. Now, there is a time, when we are able to make generalization and also create the theory of safety and security. This theory should be applied for each field of safety or security. As the part of kind of safety or security, there are models for ensuring safety or security issues. For example, the physical security is ensured through individual protection, known as barriers. Barrier ensures functions of retentions. In the article are analyzed the common theoretical models for ensuring safety and security.
