While organizations spend the next few days and weeks patching OpenSSL vulnerabilities, the realization is setting in that we may never know the full extent of the damage caused by Heartbleed. Although Heartbleed was only announced in early April, it has actually been present in OpenSSL versions dating back to March 2012. This means hackers have had ample time to steal certificates and other sensitive information. Making matters worse, it's nearly impossible for companies to know whether their web communications have indeed been compromised. What exactly is being exposed? When exploited by a hack, Heartbeat (the name of the transport layer security extension where the bug was found) dumps whatever data might reside in the memory of client/server communications in small 64k chunks. Normally this traffic is encrypted, but the bug actually compromises the secret keys, ... (more)

Intel-Cloudera Relationship Is Great for Security-Minded Hadoop Customers

Few companies are enjoying a better run of news right now than Cloudera. In mid-March the big data bell cow announced $160 million in funding led by T. Rowe Price. Less than two weeks later, Intel’s mega investment of $740 million is still a popular topic around our company’s water cooler (yes, we have a water cooler). The company’s latest salvo happened this morning while most of the west coast was still asleep. Today Cloudera announced the general availability of Cloudera 5, the solution that will drive what Cloudera refers to as the enterprise data hub. In short, the hub is a... (more)

What's Hot in Big Data

The who's who of Big Data were out in full force at Strata last week, and like the fall Strata/Hadoop World event in New York, the Santa Clara showcase did not disappoint. Allow me to share a few thoughts, straight from the Gazzang booth, which occupied prime real estate right by the food and beverage area: 1) The hype around big data has died down... a lot. Svetlana Sicular of Gartner famously (or infamously) noted early last year, big data is descending into the "Trough of Disillusionment." While that sounds awful on the surface, it's actually a sign of a maturing market. It me... (more)

A Sixth Thing CIOs Should Know About Big Data

Amid the slew of articles offering advice on Big Data,  Joab Jackson's, Five Things CIOs Should Know About Big Data. stood out because of how absolutely spot on it was. The five points he makes nearly always come up in our conversations with customers and prospects: You will need to think about big data. What we're seeing now is that the price of entry to big data, at least from a CapEx standpoint, is pretty low. Open source tools like Hadoop, Cassandra, MongoDB, MapReduce and others, combined with the relatively low price of cloud computing, means organizations that may not ha... (more)

Cloudera Has the Right Idea on Big Data Security

I'd like to address a recent blog post in CloudTweaks titled, "Cloudera Not Cutting It With Big Data Security." The author makes a number of very salient and valid points about Hadoop security… or lack thereof. Indeed the Apache Hadoop platform, which includes HDFS and MapReduce and other projects like HBase, Mahout and Hive, was not designed for security. The Hadoop name, for better or worse, is nearly synonymous with big data because it delivers the "three V's" (velocity, variety, volume) at massive scale, enabling organizations to crunch, process, analyze and retain data like...
