Computer network security is a complicated issue, involving many aspects of computer technology, network
management, network usage and maintenance. In order to increase computer network security, we should mix
various types of applications for protection measures. It is necessary to develop more effective security solving
measures, thereby to improve the computer network security prevention and. It is a long way to go to ensure the
normal operation of large-scale network system and communication and maintain sustainable and efficient transport network. To build a harmonious secure computer network security system, we need to take advantage of a variety of
integrated network security and green data networking products to form an intelligent network protection system,
and thus make computer network security meet various needs.
