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.

Accessing a secured Hadoop cluster from an enterprise network

Typical deployment architecture of a secured Hadoop cluster in an enterprise context is shown in the following diagram:

The Corporate Network is firewalled with the Hadoop cluster and connectivity is only provided through the EdgeNodes (also also known as Gateway Servers). The Gateway Server allows an entry point for external applications, tools, and users to the secured Hadoop cluster. It is deployed between the Hadoop cluster and the corporate network. As all users log in to this machine and the credentials for the user defined in this machine are used while accessing the Hadoop cluster, this node can be used to provide access control, policy enforcement, logging, and gateway services to the Hadoop environment. Depending on the number of users accessing the Hadoop cluster, there could be more than one Gateway Server in a Hadoop cluster.

Clients in the corporate network can't directly access the Hadoop cluster. They log in...
