Secure your Amazon EMR cluster from unintentional network exposure with Block Public Access configuration
This post discusses a new account level feature called Block Public Access (BPA) configuration that helps administrators enforce a common public access rule across all of their EMR clusters in a region.
Perimeter security helps secure Apache Hadoop cluster resources to users accessing from outside the cluster. It enables a single access point for all REST and HTTP interactions with Apache Hadoop clusters and simplifies client interaction with the cluster. For example, client applications must acquire Kerberos tickets using Kinit or SPNEGO before interacting with services on Kerberos enabled clusters. In this post, we walk through setup of Apache Knox to enable perimeter security for EMR clusters.
