How-to: Secure Apache Solr Collections and Access Them Programmatically

Categories: Platform Security & Cybersecurity Search Sentry

Learn how to secure your Solr data in a policy-based, fine-grained way.

Data security is more important than ever before. At the same time, risk is increasing due to the relentlessly growing number of device endpoints, the continual emergence of new types of threats, and the commercialization of cybercrime. And with Apache Hadoop already instrumental for supporting the growth of data volumes that fuel mission-critical enterprise workloads, the necessity to master available security mechanisms is of vital importance to organizations participating in that paradigm shift.
