The era of big data promotes the development of computer network, which plays a very important role. Big data can improve people’s life and work enthusiasm with high quality, and further sublimate the standard of the masses. Because of the openness of computer network, it always leads to unnecessary security problems. Therefore, in order to apply the computer network on a large scale and avoid the information leakage caused by the network, this paper proposes the research on the design of computer network security defense system based on the background of big data. First of all, the importance of computer network security is discussed; secondly, the types of network security attacks are discussed, and the computer network security defense system is built by using multi angle and active security defense strategy to maintain the safe operation of the network; then, the risk algorithm is analyzed, and the risk of the whole computer network can be estimated by setting the weight according to the importance of the obtained resources So as to formulate reasonable safety measures. Finally, through the system test, the system has good analysis ability and defense ability, and has outstanding effect in computer network defense.
