What you get with this Offer
I will implement a comprehensive Hadoop security configuration for your cluster — covering Kerberos authentication for all Hadoop services, Apache Ranger for fine-grained access control policies (HDFS directory, Hive table and column, HBase table), Apache Knox as an API gateway for perimeter security, HDFS encryption zones for data at rest, and wire encryption with TLS for data in transit. A Hadoop cluster without authentication is a single-network-access event away from full data exposure; Kerberos and Ranger together provide the authentication and authorisation layers required for any production cluster handling sensitive or regulated data.
The implementation covers MIT KDC or Active Directory Kerberos integration, service principal and keytab creation for all Hadoop services, HDFS and YARN kerberisation, Ranger admin installation and service plugin deployment, HDFS and Hive access policy creation, Knox topology configuration for WebHDFS and HiveServer2 proxying, HDFS encryption key management (Ranger KMS), and TLS configuration for HDFS, YARN, and Hive. A security runbook is included.
This service suits organisations handling personally identifiable information, financial data, healthcare records, or any regulated data in a Hadoop cluster and needing to implement or strengthen their security posture.
