Identifies File Layer Encryption as Cornerstone for Protecting Data at Rest

SAN JOSE, Calif. - Nov. 5, 2012 - Thales, Inc., the leader in enterprise encryption and key management, today announced that it has released a whitepaper licensed from information security research and advisory firm Securosis entitled, "Securing Big Data: Securosis Recommendations for Hadoop and NoSQL Environments". This independent report explores the security problems that big data users face and offers pragmatic advice on how to secure their environments.

According to Securosis, "During this research project two factors became abundantly clear. First, big data projects are common -- almost the norm -- within the enterprises we spoke with. They have embraced the technology, and they've pushed vast amounts of data into these clusters. Second, most have implemented virtually zero security measures beyond user passwords". The research paper summarizes the state of security for 'big data' environments, and reviews both built in protections, as well as weaknesses within these systems.

"Based on Securosis' findings, security in typical big data implementations is largely an afterthought," said Derek Tumulak, vice president of product management for Thales. "The good news is that several critical security concerns can be addressed by a handful of security measures, including the use of file layer encryption to protect data at rest and ensure sensitive information cannot be accessed."

The research paper covers the following topics:

  • Architecture: What's different about big data systems, both in how they process information and how they are deployed? How do these differences impact data and database security?
  • Operations: What operational security issues exist within big data platforms? What are the challenges associated with securing big data and the deficiencies of the systems used to manage it -- particularly their lack of native security features
  • Recommendations: What strategies work best for securing big data repositories, including tactical recommendations for securing certain facets of these environments, and the gaps where no good solutions exist
