Find out how to implement entry management and auditing on Amazon Redshift utilizing Immuta


This publish is co-written with Matt Vogt from Immuta. 

Organizations are in search of merchandise that permit them spend much less time managing information and extra time on core enterprise capabilities. Knowledge safety is likely one of the key capabilities in managing a knowledge warehouse. With Immuta integration with Amazon Redshift, person and information safety operations are managed utilizing an intuitive person interface. This weblog publish describes how one can arrange the mixing, entry management, governance, and person and information insurance policies.

Amazon Redshift is a completely managed, petabyte-scale, massively parallel information warehouse that makes it quick and cost-effective to investigate all of your information utilizing commonplace SQL and your current enterprise intelligence (BI) instruments. Right now, tens of 1000’s of shoppers run business-critical workloads on Amazon Redshift. Amazon Redshift natively helps coarse-grained and fine-grained entry management with options similar to role-based entry management, scoped permissionsrow-level safety, column-level entry management and dynamic information masking.

Immuta allows organizations to interrupt down the silos that exist between information engineering groups, enterprise customers, and safety by offering a centralized platform for creating and managing coverage. Entry and safety insurance policies are inherently technical, forcing information engineering groups to take accountability for creating and managing these insurance policies. Immuta empowers enterprise customers to successfully handle entry to their very own datasets and it allows enterprise customers to create tag and attribute-based insurance policies. By means of Immuta’s pure language coverage builder, customers can create and deploy information entry insurance policies without having assist from information engineers. This distribution of insurance policies to the enterprise allows organizations to quickly entry their information whereas making certain that the correct folks use it for the correct causes.

Answer overview
