NSA Extends Label-based Security to Big Data Stores

The National Security Agency has submitted new label-based data store software, called Accumulo, to the Apache Software Foundation, in hopes that other parties will further develop the technology for use in secure systems.

"There is a need for a flexible, high performance distributed key/value store that provides expressive, fine-grained access labels," the developers stated on the proposal page submitted to Apache. "We have made much progress in developing this project over the past [three] years and believe both the project and the interested communities would benefit from this work being openly available and having open development."
