One of the most popular platforms for Big Data processing is Apache Hadoop. Originally designed without security in mind, Hadoop’s security model has continued to evolve. Its rise in popularity has brought much scrutiny, and as security professionals have continued to point out potential security vulnerabilities and Big Data Security risks with Hadoop, this has led to continued security modifications to Hadoop. There has been explosive growth in the “Hadoop security” marketplace, where vendors are releasing “security-enhanced” distributions of Hadoop and solutions that compliment Hadoop security. This is evidenced by such products as Cloudera Sentry, IBM InfoSphere Optim Data Masking, Intel's secure Hadoop distribution, DataStax Enterprise, DataGuise for Hadoop, Protegrity Big Data Protector for Hadoop, Revelytix Loom, Zettaset Secure Data Warehouse, and the list could go on. At the same time, Apache projects, such as Apache Accumulo provide mechanisms for adding additional security when using Hadoop. Finally, other open source projects, such as Knox Gateway (contributed by HortonWorks) and Project Rhino (contributed by Intel) promise that big changes are coming to Hadoop itself. https://intellipaat.com/
