Many Hadoop clusters lack even the most basic security controls. This is due to several factors: some security features did not exist as recently as two years ago, and the complexity of Hadoop security has proved daunting to administrators.
Mark Donsky, André Araujo, Michael Yoder, and Manish Ahluwalia walk you through securing a Hadoop cluster. You’ll start with a cluster with no security and then add security features related to authentication, authorization, encryption of data at rest, encryption of data in transit, and complete data governance.
For each security feature, Mark, André, Michael, and Manish cover the following topics:
Mark Donsky leads product management at Okera, a software provider that provides discovery, access control, and governance at scale for today’s modern heterogeneous data environments. Previously, Mark led data management and governance solutions at Cloudera. Mark has held product management roles at companies such as Wily Technology, where he managed the flagship application performance management solution, and Silver Spring Networks, where he managed big data analytics solutions that reduced greenhouse gas emissions by millions of dollars annually. He holds a BS with honors in computer science from the University of Western Ontario.
André Araujo is a principal solutions architect at Cloudera. An experienced consultant with a deep understanding of the Hadoop stack and its components and a methodical and keen troubleshooter who loves making things run faster, André is skilled across the entire Hadoop ecosystem and specializes in building high-performance, secure, robust, and scalable architectures to fit customers’ needs.
Mike Yoder is a software engineer at Cloudera who has worked on a variety of Hadoop security features and internal security initiatives. Most recently, he implemented log redaction and the encryption of sensitive configuration values in Cloudera Manager. Prior to Cloudera, he was a security architect at Vormetric.
Manish Ahluwalia is a security engineering at Nerdwallet. Manish has held software architect roles at Tibco Loglogic and Thales Vormetric and was a security engineer at Cloudera, where he focused on the security of the Hadoop ecosystem. Manish has been working in big data since its infancy in various companies in Silicon Valley. He is most passionate about security.
