Analysis of Hadoop Security Mechanism Based on Kerberos Security Model Optimization

Hadoop is a distributed computing framework, which was originally designed to process large-scale data sets. However, with the wide application of Hadoop in enterprises, its security has become more and more important. Kerberos is a network authentication protocol, which is used to provide secure authentication services. Hadoop's integration with Kerberos can provide it with a powerful security mechanism. However, with the wide application of Hadoop in enterprise environment, the basic security mechanism relying solely on Kerberos can no longer meet the increasingly complex security requirements. Therefore, this paper proposes an optimization model of Hadoop security mechanism based on Kerberos to improve the overall security of Hadoop cluster. The experimental results show that the security of Hadoop cluster has been significantly improved by implementing these optimization measures. Therefore, the research in this paper has important theoretical and practical significance for promoting the development and improvement of Hadoop security mechanism.
