Background

Network security is the security protection of technologies and management established and adopted by data processing systems, protecting computer hardware, software and data from being damaged, altered and revealed by casual and malicious reasons. The security of a computer network can thus be understood as: by adopting various technologies and management measures, the network system can normally operate, thereby ensuring the availability, integrity and confidentiality of network data. Therefore, the purpose of establishing network security measures is to ensure that data transmitted and exchanged over the network is not subject to increase, modification, loss, leakage, and the like.

With the rapid development of internet technology and electronic commerce, more and more businesses are moving to the network such as online government offices, online digital banks, online shopping, etc., and at the same time, more and more information related to personal privacy and trade secrets need to be transmitted through the network. However, malicious threats such as viruses, hackers, network transactions, and phishing and fraud in webpages pose a great challenge to the security of online transactions. The network firewall technology is a special network interconnection device for strengthening access control between networks, preventing external network users from entering an internal network through the external network by illegal means, accessing internal network resources and protecting the internal network operating environment. It carries out a check on the data packets transmitted between two or more networks, such as the link mode, according to a certain security policy, to determine whether the communication between the networks is allowed or not, and monitors the operation state of the networks. The existing firewall products mainly comprise a bastion host, a packet filtering router, an application layer gateway (proxy server), a circuit layer gateway, a shielding host firewall, a double host and the like. The network safety isolation device is arranged on the ground and a desktop, so that the network safety isolation device is easy to move and affects the use, and the network safety isolation device is arranged on the desk or the wall body in order in office places.
