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.

Chapter 2. Hadoop Security Design

In Chapter 1, Hadoop Security Overview, we discussed the security considerations for an end-to-end Hadoop-based Big Data ecosystem. In this chapter, we will narrow our focus and take a deep dive into the security design of the Hadoop platform. Hadoop security was implemented as part of the HADOOP-4487 Jira issue, starting in late 2009 ( Currently, there are efforts to implement SSO Authentication in Hadoop. This is currently not production-ready, and hence will be out of scope of this book.

Hadoop security implementation is based on Kerberos. So in this chapter, first we will be provided with a high-level overview of key Kerberos terminologies and concepts, and then we will look into the details of the Hadoop security implementation.

The following are the topics we'll be covering in this chapter:

  • What is Kerberos?

  • The Hadoop default security model

  • The Hadoop Kerberos security implementation
