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. However, it’s incumbent on security admins to ensure a consistently secured and governed experience for end users and administrators across multiple workloads that span on-premises, private cloud, multicloud, and hybrid cloud deployments.
Mark Donsky, Steffen Maerkl, and André Araujo share best practices for meeting these challenges as they 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, Steffen, and André cover the following topics:
