How Testing Supports Production-Ready Security in Cloudera Search

Categories: Search Security Sentry Testing

Security architecture is complex, but these testing strategies help Cloudera customers rely on production-ready results.

Among other things, good security requires user authentication and that authenticated users and services be granted access to those things (and only those things) that they’re authorized to use. Across Apache Hadoop and Apache Solr (which ships in CDH and powers Cloudera Search), authentication is accomplished using Kerberos and SPNego over HTTP and authorization is accomplished using Apache Sentry (the emerging standard for role-based fine grain access control,

New in CDH 5.1: Document-level Security for Cloudera Search

Categories: CDH Search Security

Cloudera Search now supports fine-grain access control via document-level security provided by Apache Sentry.

In my previous blog post, you learned about index-level security in Apache Sentry (incubating) and Cloudera Search. Although index-level security is effective when the access control requirements for documents in a collection are homogenous, often administrators want to restrict access to certain subsets of documents in a collection.

For example,

Index-Level Security Comes to Cloudera Search

Categories: Hadoop Search Security

The integration of Apache Sentry with Apache Solr helps Cloudera Search meet important security requirements.

As you have learned in previous blog posts, Cloudera Search brings the power of Apache Hadoop to a wide variety of business users via the ease and flexibility of full-text querying provided by Apache Solr.
