Hadoop Elephant in Active Directory Forest - Marek Gawiński, Allegro Group Sp. z o.o.
Active Directory (AD) is a well known industry standard to authenticate employees in back office services. It assures password management and clear policies for requesting and gaining access to secured resources.
Integrating AD with Hadoop infrastructure brings those benefits to Big Data world. It also includes other features that make big data developers’ tasks much easier. For example our developers can submit Spark applications that use HDFS, YARN and Hive directly from their IDE.
In this talk we provide technical details which include:
Making AD users and groups visible to Linux via System Security Services Daemon.
Integrating new Linux servers automatically with AD forest on Kerberos level with all credentials needed.
Making whole architecture non-vulnerable to AD service unavailabilities.
Auto-deployment and autoconfiguration of Hadoop clients’ software on users desktops.

Protecting Enterprise Data In Apache Hadoop - Owen O'Malley, Hortonworks
Hadoop has long had strong authentication via integration with Kerberos,
authorization via User/Group/Other HDFS permissions, and auditing via
the audit log. Recent developments in Hadoop have added HDFS file access
control lists, pluggable encryption key provider APIs, HDFS snapshots,
and HDFS encryption zones. These features combine to give important new
data protection features that every company should be using to protect
their data. This talk will cover what the new features are
and when and how to use them in enterprise production environments.
Upcoming features including columnar encryption in the ORC columnar format
will also be covered. By encrypting particular columns, enterprises can
control which users have access to particularly sensitive columns that
contain personally identifiable information or financial information.

Encryption and Anonymization in Hadoop - Current and Future - Balaji Ganesan, Hortonworks and Don Bosco Durai
As enterprises expand usage of Hadoop as a platform to store and process data, data security and compliance needs in the platform are becoming more pertinent.
Beyond the traditional Hadoop security controls of authentication through Kerberos, or access management through Apache Ranger, users are increasingly asking for encrypting data when it is being transmitted or when data is stored in disk. In relation to this, there is a movement towards anonymizing the data by tokenizing or masking it, with the intent of using the data in the query processing while protecting the sensitivity by hiding the original value from the end user.
The community has recently built encryption in HDFS file system. In this talk we look at the current encryption capabilities in Hadoop and areas where the community need to focus to further enhance Hadoop as an enterprise ready data platform.

Apache Sentry (incubating) : Fine-Grained Access Control to Hadoop Ecosystem - Sravya Tirukkovalur, Cloudera
Historically, each Hadoop component offers its own method of access control so each one needs its own set of permissions rules - even when they are accessing the same data in Hadoop. This is an administrative nightmare that slows the adoption of Hadoop when sensitive data is involved. Apache Sentry is a framework that enables fine grained, role based authorization for multiple Hadoop ecosystem components. Apache Sentry is a highly modular system that support authorization for various data models like Database style schemas, search indexes etc. It comes with out of the box support for SQL query frameworks like Apache Hive and Cloudera Impala Apache Hive, extending the table privileges to underlying HDFS storage, as well as open source search framework Apache Solr. This session will present an overview of Apache Sentry.

How to Deploy a Secure, High-Available, Hadoop Platform - Olaf Flebbe, science+computing ag
We demonstrate the fully automatic installation of a hadoop cluster including infrastructure. The basic building blocks of the Demonstration are the Debian Distribution incl. puppet, configuration with hiera, a list of community puppet modules and deploy scripts and packages from the apache bigtop distribution. The automatically installed cluster sports an HA MIT Kerberos and openLDAP setup, apache zookeeper fencing, HA Hadoop ( journalling, and RM). WebGUI’s are authenticated with SPNEGO, Hive is configured with standard SQL authorization and Hue is provided as frontend.

One of the advanced features is the use of puppets CA via PKINIT for preauthentication and bootstrapping a secure kerberos KDC and securing hadoop with it.

Hadoop and Kerberos: the Madness Beyond the Gate - Steve Loughran, Hortonworks
When HP Lovecraft wrote of forbidden knowledge about non-human deities, knowledge which would reduce the reader to insanity, most people assumed that he was making up a fantasy world. In fact he was documenting Kerberos and its Hadoop integration.

There are some things humanity was not meant to know. Most people are better off living lives of naive innocence, never having to see an error message about SASL or GSS, to never stare in terror at classes only whose initials, UGI, are ever spoken aloud -or more accurately, whispered.

This talk goes into the depths, to the knowledge which you need to write applications in a secure Hadoop cluster, knowledge that may drive you insane. Forever more, you shall fear voices calling out in the night, voices saying things like "we have an urgent Kerberos-related support call -can you help?"

Securing Hadoop in an Enterprise Context - Hellmar Becker, ING
Hadoop clusters can be secured using Kerberos and LDAP, and tools like Ranger and Sentry facilitate security administration. How do you connect a cluster to an enterprise directory with 100,000+ users and centralized role and access management? Hellmar will present ING's approach to synchronize Hadoop role management with the central repository, emphasizing aspects of performance and system stability. He will discuss specific changes to the Ranger security tool that ING introduced to mitigate directory server load, and general aspects of the security model.
