NSA Extends Label-based Security to Big Data Stores
Source: PC World - Posted by Anthony Pell   
SELinux 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."

Based on Google BigTable design, Accumulo is a simple key/value data store, where providing the system with the key will return the data associated with that key. A distributed design, Accumulo can be run across multiple servers, making it a candidate for use in big data systems.
