In the era of big data, the network has provided convenience and also brought potential threats. Viruses, Trojan horses, and hackers' attacks have caused irretrievable losses for people, and they have become a major obstacle for the expansion of internet. This paper first analyzes the related concepts of big data and the current situation of network security of port of port in the era of big data, then uses the five indicators of network security of port of port to establish a network security of port of port evaluation model, and finally puts forward the countermeasures for ensuring information security of computer networks in the era of big data.
