Entity security in computer security mainly refers to: the security of computer physical hardware entities. Physical security, also called physical security, is a measure and process to protect computer facilities (including networks) and other media from damage by earthquakes, floods, fires, harmful gases and other environmental accidents (such as electromagnetic pollution, etc.).

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

In computer information systems, computers and their related equipment and facilities (including networks) are collectively referred to as the entities of the computer information system.

Physical Security, also called physical security, protects computer facilities (including networks) and other media from damage by earthquakes, floods, fires, harmful gases and other environmental accidents (such as electromagnetic pollution, etc.) Measures and processes.

The main factors affecting computer physical security are as follows:

1) The vulnerability factors of computers and their network systems themselves.

2) Safety issues caused by various natural disasters.

3) Security problems caused by human errors and various computer crimes.

The main issues considered in physical security are the security of the environment, sites and equipment, physical access control and emergency response plans. Physical security technology mainly refers to security measures taken on the environment, sites, equipment and communication lines of computer and network systems. The purpose of physical security technology implementation is to protect computers, network servers, printers and other hardware entities and communication facilities from damage by natural disasters, human errors, and criminal acts, ensure that the system has a good electromagnetic compatibility working environment, and establish a complete safety management system , to prevent illegal entry into the computer working environment and various theft and sabotage activities.

Physical security mainly includes three aspects:

1) Environmental security: security protection of the environment where the system is located, such as regional protection and disaster protection;

2) Equipment security : Including equipment anti-theft, anti-destruction, prevention of electromagnetic information radiation leakage, anti-electromagnetic interference and power supply protection, etc.;

3) Media security: including the security of media data and the security of the media itself. Damage to computer information system entities can not only cause huge economic losses, but also lead to the loss and destruction of confidential information and data in the system.
