Evaluate Apache Ranger to provide comprehensive security across the CERN Hadoop ecosystem

This report provides an overview of a 12-week internship project conducted at CERN, focusing on the evaluation and implementation of Apache Ranger to enhance security management within the CERN Hadoop ecosystem. The Hadoop ecosystem, designed to manage large data volumes, was integrated with Apache Ranger to achieve fine-grained access control, centralised security management, LDAP integration, audit tracking, and policy enforcement. This report outlines the steps taken to deploy Apache Ranger manually, emphasising the challenges faced during installation, configuration, and integration with CERN's LDAP system. It discusses plugin setup for critical Hadoop components and the storage of audit logs. It concludes by highlighting successful accomplishments and proposing future improvements to enhance Apache Ranger's suitability for CERN's production environment.
