The effect of network security on attack reduction.

Network security involves preventing unwanted access, misuse, and theft of the underlying networking infrastructure. In order for users, apps, devices, and users to work securely, a secure infrastructure must be built. referring to network security issues as well as basic computer security issues. In actuality, when considered from this angle, computer security is a subset of network security. Although it is a fundamental component of network security policy, the art and science of cryptography and its function in ensuring secrecy, integrity, and authentication reflect another unique focus on the continuous expansion of network size, the combination of traditional industry and the Internet has become more and more extensive, people’s life has highly relied on the network. At present, the network security environment isn’t optimistic, the network attack has become increasingly frequent, the threat and loss caused also become bigger and bigger. But traditional security products can only singly reflect one or several indexes of network situation, which is already unable to satisfy the demand of administrators to timely grasp. the overall security condition of network. The network security situation sensing technology fuses the protection data of network security equipment such as Intrusion detection system, firewall, Virus detection system, which is an overall reflection of the network security situation and trend, and can be taken as an important reference for network prewarning and response.
