Study of Computer Network Security and Its Countermeasures

Computer technology is developing rapidly, so that the development of today's society can not do without information network. Since the information transfer computer network involved in all areas of finance, science and education, and military, which contains significant economic or national interests, it ultimately forms from cyber attacks on all sides, and also a variety of network attacks, such as virus infection, data theft, tampering delete information add more. From the aspect of network information security vulnerabilities, network security technology major, common network attacks and countermeasures, network security, construction and other analyzes the main problems of the current network information security presence, and common network attacks from the technical level proposed solutions We hope the gradual elimination of network information security risks through the network security building.
