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 to set up the Kerberos authentication protocol and how to add the required principals to the KDC. We then looked at the overall process of configuring the Hadoop security with Kerberos. The Hadoop configurations have to be replicated in all the nodes of the cluster. All users running MapReduce need to set up on all nodes of the cluster. Setting up users across the entire cluster nodes can be challenging and setting up an Active Directory- or LDAP-based authentication mechanism avoids the problem of manually creating the users in each of the cluster nodes.

In the next chapter, we will look at how we can configure Kerberos security for the rest of the Hadoop ecosystem such as Hive, WebHDFS, Oozie, and Flume.
