为数据处理系统建立和采用的技术和管理的安全保护，保护计算机硬件、软件和

The technology and management safety protection established and adopted for the data processing system to protect the computer hardware, software and data from damage, modification and leakage due to accidental and malicious reasons. Therefore, the security of the computer network can be understood as: the normal operation of the network system through the use of various technologies and management measures, thereby ensuring the availability, integrity and confidentiality of network data. Therefore, the purpose of establishing network security protection measures is to ensure that data transmitted and exchanged through the network will not increase, modify, lose, or leak.

Secure the technology and management established and adopted for data processing systems to protect computer hardware, software, and data from accidental and malicious damage, change, and disclosure. Thus the security of the computer network can be understood as ensuring the availability, integrity and confidentiality of network data by adopting various technical and administrative measures to keep the network system up and running. Therefore, the purpose of establishing network security protection measures is to ensure that data transmitted and exchanged over the network does not increase, modify, lose, and disclose.

For the data processing system to establish and adopt the technology and management of security protection, to protect computer hardware, software and data from accidental and malicious causes of damage, change and leakage. Therefore, the security of computer network can be understood as: through the use of various technologies and management measures, make the network system run normally, so as to ensure the availability, integrity and confidentiality of network data. Therefore, the purpose of establishing network security protection measures is to ensure that the data transmitted and exchanged through the network will not be increased, modified, lost and leaked.<br>
