DarkSentry

Apache Sentry™ is a system for enforcing fine grained role based authorization to data and metadata stored on a Hadoop cluster. Apache Sentry has successfully graduated from the Incubator in March of 2016 and is now a Top-Level Apache project. Apache Sentry is a granular, role-based authorization module for Hadoop. Sentry provides the ability to control and enforce precise levels of privileges on data for authenticated users and applications on a Hadoop cluster. Sentry currently works out of the box with Apache Hive, Hive Metastore/HCatalog, Apache Solr, Impala and HDFS (limited to Hive table data). Sentry is designed to be a pluggable authorization engine for Hadoop components. It allows you to define authorization rules to validate a user or application’s access requests for Hadoop resources. Sentry is highly modular and can support authorization for a wide variety of data models in Hadoop.

SonicSentry MDR is a managed detection and response cybersecurity service from SonicWall that gives organizations, especially MSPs, 24/7 expert Security Operations Center (SOC) monitoring, threat detection, threat hunting, and rapid mitigation across endpoints, cloud applications, and networks, helping stop active attacks and reduce breach dwell time. It processes alerts around the clock, recognizes patterns that indicate emerging threats, and responds immediately to contain and neutralize security incidents, eliminating alert fatigue and letting internal teams focus on strategic priorities instead of constantly watching logs. SonicSentry extends protection from simple alerting to proactive defense, auditing configurations, and ensuring optimal security rules are in place, and it can be paired with advanced endpoint tools like CrowdStrike Falcon or existing security stacks for layered resilience.
