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.

The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data...

Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.

As organizations realize the scope of the Internet of Things, gaining key insights from Big Data, through the use of advanced analytics, becomes crucial. However, IoT also creates the need for petabyte scale storage of data from millions of devices. A new type of Storage is required which seamlessly integrates robust data analytics with massive scale. These storage systems will act as “smart systems” provide in-place analytics that speed discovery and enable businesses to quickly derive meaningf...

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.

Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem"...
