Comprehensive Security Across the Hadoop Infrastructure

As big data technologies like Hadoop become widely deployed in production environments, the expectation is that they will meet the enterprise requirements in data governance, operations and security while integrating with existing data center infrastructure. …

We are in the midst of a data revolution. Hadoop, powered by Apache Hadoop YARN, enables enterprises to store, process, and innovate around data at a scale never seen before making security a critical consideration. Enterprises are looking for a comprehensive approach to security for their data to realize the full potential of the Hadoop platform unleashed by YARN, the architectural center and the data operating system of Hadoop 2.

Hortonworks and the open community continue to work tirelessly to enhance security in Hadoop.…

This is a guest blog from Protegrity, a Hortonworks certified partner.

As Hadoop transitions to take on a more mission critical role within the data center, so the top IT imperatives of process innovation, operational efficiency, and data security naturally follow. One such imperative in particular now tops the requirement list for Hadoop consideration within the enterprise: a well-developed framework to secure data.

The open source community has responded. Work is underway to build out a comprehensive and coordinated security framework for Hadoop that can work well with existing IT security investments.…

Introduction

HDP 2.1 ships with Apache Knox 0.4.0. This release of Apache Knox supports WebHDFS, WebHCAT, Oozie, Hive, and HBase REST APIs.

Hive is a popular component used for SQL access to Hadoop, and the Hive Server 2 with Thrift supports JDBC access over HTTP. The following steps show the configuration to enable a JDBC client to talk to Hive Server 2 via Knox (Beeline > JDBC over HTTPS > Knox > HTTP > Hive Server2).…

This is a quest blog from Voltage Security, a Hortonworks partner.

Data Security for Hadoop is a critical requirement for adoption within the enterprise. Organizations must protect sensitive customer, partner and internal information and adhere to an ever-increasing set of compliance requirements. The security challenges these organizations are facing are diverse and the technology is evolving rapidly to keep pace. 

An Open Community For Platform Security

The open source community, including Hortonworks, has invested heavily in building enterprise grade security for Apache Hadoop. …

In May, Hortonworks acquired XA Secure and made a promise to contribute this technology to the Apache Software Foundation.  In June, we made it available for all to download and use from our website and today we are proud to announce this technology officially lives on as Apache Argus, an incubator project within the ASF.

This podling has been formed and now the process of graduating Argus to a top-level project (TLP) has begun.…

This is a guest post from Hortonworks partner, Dataguise. Dataguise is a HDP 2.1 certified technology partner providing sensitive data discovery, protection and reporting in Hadoop.

According to a 2013 Global Data Breach study by the Ponemon Institute, the average cost of data loss exceeds $5.4 million per breach, and the average per person cost of lost data approaching $200 per record in the United States. That said, no industry is spared from this threat and all of our data systems, including Hadoop, need to address the security concern.…

“Data is to information society what fuel was to the industrial economy: the critical resource powering the innovations that people rely on,” write Victor Mayer-Schönberger and Kenneth Cukier, in Big Data. Today, big data fuels and engenders innovation of new products and services, according to Forrester.

Just as countries’ fuel repositories need protection and security because they can come under attack, so do companies’ big data repositories. “Companies, markets, and countries are increasingly under attack from cyber-criminals.…

Hadoop is a business-critical data platform at many of the world’s largest enterprises. These corporations require a layered security model focusing on four aspects of security: authentication, authorization, auditing, and data protection. Hortonworks continues to innovate in each of these areas, along with other members of the Apache open source community. In this blog, we will look at the authentication layer and how we can enforce strong authentication in HDP via Kerberos.…

IBM InfoSphere Guardium has certified with HDP 2.1. The  Hortonworks Certified Technology Program simplifies big data planning by providing pre-built and validated integrations between leading enterprise technologies and HDP. 

Kathryn Zeidenstein, InfoSphere Guardium Evangelist, is our guest blogger and describes security, Hadoop, and the Guardium solution.

Those of us in the data security and privacy space tend to worry a lot. With each new breaking story on the latest data breach, and with the subsequent fallout, people higher and higher up the food chain are also worrying a lot.…

This week we hosted a webinar entitled HDP Advanced Security: Comprehensive Security for Enterprise Hadoop. Over 135 people attended, prompting an informative discourse and a series of questions.

The speakers outlined the HDP Advanced Security features and benefits in Hortonworks Data Platform and gave a demo. Thanks to our presenters Justin Sears (Hortonworks’ Product Marketing Manager), Balaji Ganesan (Hortonworks’ Senior Director, Enterprise Security Strategy), and Don Bosco Durai (Hortonworks’ Enterprise Security Architect).…

Two months ago, we announced the acquisition of XA Secure. and at that time we stated that the software would be generally available by the end of June. We are happy to announce that we have delivered as promised and the solution is available for download for everyone today. Also, if you are an HDP Enterprise Plus Subscription customer, additional support for these new functions is now provided.

HDP Advanced Security expands on the solid security features already found in HDP to provide central administration and coordinated enforcement of enterprise security policy for a Hadoop cluster.…

It has been an exciting  few weeks for the XA Secure team. We formally joined Hortonworks on 5/15 and have received a warm  welcome from our new peers. Even more exciting are the numerous discussions we have had with current customers and prospects on how we can bring together a comprehensive and holistic security capabilities to HDP.  We now begin the journey to incubate our XA Secure functionality as a completely open source project governed by the Apache Software Foundation.…

Customers’ Hadoop Journey

We’ve all had two weeks to reflect on Hadoop Summit 2014. One of the biggest differences that stood out in this year’s Summit (as compared to Summit 2013) was the presence of large enterprise customers that are using Apache Hadoop as an important part of their modern data architectures.

Hadoop has gone beyond its original Yahoo use case—indexing the web via a nightly batch MapReduce process —and into the mainstream of daily data processing and analytics with real-time, online, interactive, and batch applications at many notable companies.…

Enterprises are using Apache Hadoop powered by YARN as a Data Operating System to run multiple workloads and use cases instead of using it just as a single purpose cluster.

A multi-purpose enterprise wide data platform often referred to as a data lake gives rise to the need for a comprehensive approach to security across the Hadoop platform and the workloads. Few weeks back Hortonworks acquired XA Secure to further execute on our vision to bring a holistic security framework to the Hadoop community irrespective of the workload.…
