Research on computer network security problems and protective measures under the background of big data

Abstract

In the information age, human beings have entered the era of big data due to the large-scale data generated every day. Computer networks in people's lives are very common. In the construction of social infrastructure and economic development, networks and information systems are essential core elements. When a network attack fails due to a malicious attack, it will bring about more serious security accidents, which will make the public interest and the national economy safe. Studying and strengthening the detection of cyberattacks to provide basic security for network infrastructure is the core link to ensure the controllability of core technical equipment and the construction of a national network security system. Therefore, this paper first analyzes big data, network security models and intrusion detection frameworks, and analyzes the key issues facing computer network security under the current circumstances. Protective measures are used to reduce the various security problems caused thereby, to prevent computer users from suffering major losses.
