Research on computer network information security and preventive countermeasures

Abstract

The collection, transmission and use of information are inseparable from the network. Precisely because the broad applications of computer network information security vulnerability and complexity. Makes computer networks more and more attacks, security has also become increasingly vulnerable, so that information security is growing more difficult. This article from network information security vulnerabilities, network security for common network attacks and countermeasures, to prevent the main construction principles of network security technologies, such as analysis of the various aspects of the current network information security issues, and solutions to common network attacks raised the technical level of, and the principles of network security. At its core are key to preventing network security technologies, and the comparison of several key technologies.
