Is there a difference between security engineering and national defense, is military security the sa

There is no relevance, security mainly focuses on "social security"; National defense generally refers to the construction of the army and the modernization of equipment.

It's a big difference, it's two different concepts entirely.

Security engineering, simple and intuitive to give a few examples, including: community guard room, gate, car barrier, pedestrian swing gate, unit video intercom, emergency button, monitoring system ......public places, factories, etc., and more complex equipment).

National defense is a permanent military project built by a state on the national territory (a general term for land, sea, and air space under the jurisdiction of a sovereign state) in peacetime in order to defend against foreign armed aggression. For example, permanent position projects, communications hub projects, military port and military airport projects, missile base projects, military traffic projects and rear projects, large command posts, and large rear warehouses are built on the border defense line and in depth on predetermined battlefields.

Security engineering is an emerging profession that people pay more and more attention to, as far as the current development is concerned, the application of security system engineering is becoming more and more popular, and the scientific and technological content is getting higher and higher. Almost all high-tech technologies can promote their development, especially the advent of the information age, which provides opportunities for the development of this profession. Security refers to "security protection".

Security by physical defense, civil air defense, technical defense three forms of protection, where the security engineering refers to technical prevention. Security engineering is to realize the use of modern scientific and technological means to achieve the process of security protection, security products are the equipment that serves the security engineering. Security engineering includes building intelligence (building intercom, etc.), ** monitoring, access control attendance, anti-theft alarm, parking lot management, smart home, computer room engineering, etc.

Military security and national defense security are not the same. Military security is a security issue on the domestic regime, which is used in ideological reform! National defense is naturally of a military nature, and problem-solving methods are not the same thing as military affairs, and the main differences between the two are as follows:
