Big Data Security for Apache Hadoop

Ten Tips for HadoopWorld attendees

Big Data takes center stage today at the Strata Conference & Hadoop World in New York, the world’s largest gathering of the Apache Hadoop™ community. A key conversation topic will be how organizations can improve data security for Hadoop and the applications that run on the platform. As you know, Hadoop and similar data stores hold a lot of promise for organizations to finally gain some value out of the immense amount of data they're capturing. But HDFS, Hive and other nascent NoSQL technologies were not necessarily designed with comprehensive security in mind. Often what happens as big data projects grow is sensitive data like HIPAA data, PII and financial records get captured and stored. It's important this data remains secure at rest.

I polled my fellow co-workers at Gazzang last week, and asked them to come up with a top ten list for securing Apache Hadoop. Here's what they delivered. Enjoy:

Think about security before getting started – You don’t wait until after a burglary to put locks on your doors, and you should not wait until after a breach to secure your data. Make sure a serious data security discussion takes place before installing and feeding data into your Hadoop cluster.

Consider what data may get stored – If you are using Hadoop to store and run analytics against regulatory data, you likely need to comply with specific security requirements. If the stored data does not fall under regulatory jurisdiction, keep in mind the risks to your public reputation and potential loss of revenue if data such as personally identifiable information (PII) were breached.

Encrypt data at rest and in motion – Add transparent data encryption at the file layer as a first step toward enhancing the security of a big data project. SSL encryption can protect big data as it moves between nodes and applications.

As Securosis analyst Adrian Lane wrote in a recent blog, “File encryption addresses two attacker methods for circumventing normal application security controls. Encryption protects in case malicious users or administrators gain access to data nodes and directly inspect files, and it also renders stolen files or disk images unreadable. It is transparent to both Hadoop and calling applications and scales out as the cluster grows. This is a cost-effective way to address several data security threats.”

Store the keys away from the encrypted data – Storing encryption keys on the same server as the encrypted data is akin to locking your house and leaving the key in your front door. Instead, use a key management system that separates the key from the encrypted data.

Institute access controls – Establishing and enforcing policies that govern which people and processes can access data stored within Hadoop is essential for keeping rogue users and applications off your cluster.

Require multi-factor authentication - Multi-factor authentication can significantly reduce the likelihood of an account being compromised or access to Hadoop data being granted to an unauthorized party.

Use secure automation – Beyond data encryption, organizations should look to DevOps tools such as Chef or Puppet for automated patch and configuration management.

Frequently audit your environment – Project needs, data sets, cloud requirements and security risks are constantly changing. It’s important to make sure you are closely monitoring your Hadoop environment and performing frequent checks to ensure performance and security goals are being met.

Ask tough questions of your cloud provider – Be sure you know what your cloud provider is responsible for. Will they encrypt your data? Who will store and have access to your keys? How is your data retired when you no longer need it? How do they prevent data leakage?

Centralize accountability – Centralizing the accountability for data security ensures consistent policy enforcement and access control across diverse organizational silos and data sets.

In his session at @ThingsExpo, Gordon Haff, Red Hat Technology Evangelist, shared examples from a wide range of industries – including en...
Detecting internal user threats in the Big Data eco-system is challenging and cumbersome. Many organizations monitor internal usage of the Big Data eco-system using a set of alerts. This is not a scalable process given the increase in the number of alerts with the accelerating growth in data volume and user base. Organizations are increasingly leveraging machine learning to monitor only those data elements that are sensitive and critical, autonomously establish monitoring policies, and to detect...
To get the most out of their data, successful companies are not focusing on queries and data lakes, they are actively integrating analytics into their operations with a data-first application development approach.
