The network has a strong openness, which can realize the communication and interaction across time and space, but it is also vulnerable to different intrusions and attacks, which leads to the leakage of data information and serious network security problems. Big data increases the complexity of computer network, which makes the security problem of computer network more prominent. Based on a comprehensive analysis of computer network security issues in the era of big data, it is of great significance to deeply explore specific network security technologies. Based on the WPDRRC network security model, this paper studies the network security technology and application in the era of big data, including virus protection technology, intrusion detection technology and access control technology. In practice, it is necessary to formulate a more secure network protection system, create a healthy and green network environment, and meet the needs of network security in the era of big data.
