Key security considerations
As discussed previously, to meet the enterprise data security needs for a Big Data ecosystem, a complex and holistic approach is needed to secure the entire ecosystem. Some of the key security considerations while securing Hadoop-based Big Data ecosystem are:
- Authentication: There is a need to provide a single point for authentication that is aligned and integrated with existing enterprise identity and access management system.
- Authorization: We need to enforce a role-based authorization with fine-grained access control for providing access to sensitive data.
- Access control: There is a need to control who can do what on a dataset, and who can use how much of the processing capacity available in the cluster.
