Securing Hadoop

By: Sudheesh Narayan

Overview of this book

Security of Big Data is one of the biggest concerns for enterprises today. How do we protect the sensitive information in a Hadoop ecosystem? How can we integrate Hadoop security with existing enterprise security systems? What are the challenges in securing Hadoop and its ecosystem? These are the questions which need to be answered in order to ensure effective management of Big Data. Hadoop, along with Kerberos, provides security features which enable Big Data management and which keep data secure. This book is a practitioner's guide for securing a Hadoop-based Big Data platform. This book provides you with a step-by-step approach to implementing end-to-end security along with a solid foundation of knowledge of the Hadoop and Kerberos security models. This practical, hands-on guide looks at the security challenges involved in securing sensitive data in a Hadoop-based Big Data platform and also covers the Security Reference Architecture for securing Big Data. It will take you through the internals of the Hadoop and Kerberos security models and will provide detailed implementation steps for securing Hadoop. You will also learn how the internals of the Hadoop security model are implemented, how to integrate Enterprise Security Systems with Hadoop security, and how you can manage and control user access to a Hadoop ecosystem seamlessly. You will also get acquainted with implementing audit logging and security incident monitoring within a Big Data platform.

In this chapter, we looked at the steps that need to be adopted to set up various Hadoop ecosystem components. At the high level, the process involves creating the Kerberos principal for each of the components and then securing the keytab file under the user's home directory. If the service has to impersonate the end user, then the service principal is configured as superuser in Hadoop. Each ecosystem component has specific configuration that needs to be updated to support secured authentication with Kerberos. Some of the components such as Sqoop or Sqoop2, leave a certain amount of security hole when used in production. So these components have to be used with caution and deployed with additional security measures.

In the next chapter, we will look at how to integrate the authentication and authorization of these ecosystem components with the Enterprise Identity Management systems.
