Download slides (PDF) Learn how to secure a Hadoop cluster for production operations Many Hadoop clusters lack even the most basic security controls. 𝗣𝗗𝗙 | Big data is defined as a large and massive volume of data can be structured, semi-structured and unstructured. One of the main.

Unlike most HDFS authentication protocols adopting public key exchange approaches, the proposed scheme uses the hash chain of keys.

The proposed scheme has the performance communication power, computing power and area efficiency as good as that of existing HDFS systems. This process is experimental and the keywords may be updated as the learning algorithm improves.

Special Issue: Convergence Security Systems. Big Data requires new technologies that efficiently collect and analyze enormous volumes of real-world data over the network [ 1 , 2 , 3 ].

In particular, open-source platforms for scalable and distributed processing of data are being actively studied in Cloud Computing in which dynamically scalable and often virtualized IT resources are provided as a service over the Internet [ 4 ].

Hadoop allows for the distributed processing of large data sets across clusters of computers [ 5 , 6 ]. Hadoop enables users to store and process huge amounts of data at very low costs, but it lacks security measures to perform sufficient authentication and authorization of both users and services [ 7 , 8 ].

Traditional data processing and management systems such as Data Warehouse and Relational Database Management Systems are designed to process structured data, so they are not effective in handling large-scale, unstructured data included in Big Data [ 9 , 10 ]. Initially, secure deployment and use of Hadoop were not a concern [ 11 , 12 , 13 ].

The data in Hadoop was not sensitive and access to the cluster could be sufficiently limited.

Associated Data

As Hadoop matured, more data and more variety of data including sensitive enterprise and personal information are moved to HDFS. For additional authentication security, Hadoop provides Kerberos that uses symmetric key operations [ 4 , 6 , 14 ]. If all of the components of the Hadoop system i.

Prerequisite knowledge General knowledge of Hadoop and system admin procedures. Learn how to secure a Hadoop cluster for production operations.

Description Many Hadoop clusters lack even the most basic security controls. What the security feature is, what protection it provides, and best practices and recommendations Planning: How to enable the feature in a phased manner with the fewest growing pains and least risk Relevance: An overview of how the implementation is performed, where the moving parts are, and potential pitfalls.

Chaos-Based Simultaneous Compression and Encryption for Hadoop

Some data symbols refer to a sequence, a segment, or a block. An application inserts or places data within a communication channel or in storage on a dedicated device.

Data stored on storage devices or transferred over communication channels between computers or networks contains significant redundancy. Data compression reduces this redundancy to save physical disk space and minimize network transmission time.

Decompression retrieves original data from compressed data and can be accomplished without data loss. Thus, data compression improves available network bandwidth and storage capacity, especially when the original data contains significant redundancy.

Data compression is an important playground for information theory, relying on its core on entropy measurement and sequences complexity measurement [ 1 ] for optimal performance. Further, compression techniques require a pattern library and only work when both sender and receiver understand the library that is utilized.

However, in general, compression does not employ secret key or password restrictions during compression and decompression, a deficiency that reduces the overall level of security. Its primary purpose is to lessen data redundancy.March 13—14, A simultaneous compression and encryption scheme is introduced that addresses an important implementation issue of source coding based on Tent Map and Piece-wise Linear Chaotic Map PWLM , which is the infinite precision of real numbers that result from their long products.
