Many big data environments lack even the most basic security and governance controls. This is due to several factors: some security features didn’t exist as recently as two years ago, and the complexity of Hadoop security has proved daunting to administrators. Nonetheless, with the emergence of regulation such as the California Consumer Protection Act (CCPA) and the General Data Protection Regulation (GDPR), organizations can no longer afford to overlook the criticality of security and governance.
Mark Donsky, Ifigeneia Derekli, Lars George, and Michael Ernest 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, they cover the following topics:
Mark Donsky is a director of product management at Okera, a software provider that provides discovery, access control, and governance at scale for today’s modern heterogenous data environments, where he leads product management. Previously, Mark led data management and governance solutions at Cloudera, and he’s 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 Western University, Ontario, Canada.
Ifi Derekli is a senior solutions engineer at Cloudera, focusing on helping large enterprises solve big data problems using Hadoop technologies. Her subject-matter expertise is around security and governance, a crucial component of every successful production big data use case. Previously, Ifi was a presales technical consultant at Hewlett Packard Enterprise, where she provided technical expertise for Vertica and IDOL (currently part of Micro Focus). She holds a BS in electrical engineering and computer science from Yale University.
Lars George is the principal solutions architect at Okera. Lars has been involved with Hadoop and HBase since 2007 and became a full HBase committer in 2009. Previously, Lars was the EMEA chief architect at Cloudera, acting as a liaison between the Cloudera professional services team and customers as well as partners in and around Europe, building the next data-driven solutions, and a cofounding partner of OpenCore, a Hadoop and emerging data technologies advisory firm. He has spoken at many Hadoop User Group meetings as well as at conferences such as ApacheCon, FOSDEM, QCon, and Hadoop World and Hadoop Summit. He also started the Munich OpenHUG meetings. He’s the author HBase: The Definitive Guide from O’Reilly.
Michael Ernest is a partner solution architect at Dataiku, supporting technical integration with cloud platforms. He previously led field-enablement programming at Cloudera, where he developed training for new and tenured hires in Hadoop operations, application architecture, and full stack security. He’s published four books on Java programming and Sun Solaris administration. Ernest lives in Berkeley, California.
