The IEEE Transactions on Big Data publishes peer reviewed articles with big data as the main focus. This problem is exaggerated in the context of the Internet of Things (IoT). This paper discusses the security issues related to big data due to inadequate research and security solutions also the needs and challenges faced by the big data security, the security framework and proposed approaches. Reliability and Availability. Furthermore, more security analysis parameters are to be investigated such as integrity and real time analysis of big data. Handlers of big data should … Big data security and privacy are potential challenges in cloud computing environment as the growing usage of big data leads to new data threats, particularly when dealing with sensitive and critical data such as trade secrets, personal and financial information. One basic feature of GMPLS/MPLS network design and structure is that the incoming or outgoing traffic does not require the knowledge of participating routers inside the core network. Therefore, header information can play a significant role in data classification. In this article, security challenges and concerns of IOT big data associated with smart grid are discussed along with the new security enhancements for identification and authentications of things in IOT big data … Analyzing and processing big data at Networks Gateways that help in load distribution of big data traffic and improve the performance of big data analysis and processing procedures. Therefore, security implementation on big data information is applied at network edges (e.g., network gateways and the big data processing nodes). Copyright © 2018 Sahel Alouneh et al. The core network consists of provider routers called here P routers and numbered A, B, etc. Review articles are excluded from this waiver policy. Therefore, a big data security event monitoring system model has been proposed which consists of four modules: data collection, integration, analysis, and interpretation [ 41 ]. It can be clearly seen that the proposed method lowers significantly the processing time for data classification and detection. Therefore, in this section, simulation experiments have been made to evaluate the effect of labeling on performance. When considering a big data solution, you can best mitigate the risks through strategies such as employee training and varied encryption techniques. Each node is also responsible for analyzing and processing its assigned big data traffic according to these factors.

Actually, the traffic is forwarded/switched internally using the labels only (i.e., not using IP header information). Using labels in order to differentiate between traffic information that comes from different networks. This is a common security model in big data installations as big data security tools are lacking and network security people aren’t necessarily familiar with the specific requirements of security big data systems. The first tier classifies the data based on its structure and on whether security is required or not. 52 ibid. Management topics covered include evaluation of security measures, anti-crime design and planning, staffing, and regulation of the security … France, Copyright @ 2010 International Journal Of Current Research. At this stage, the traffic structure (i.e., structured or unstructured) and type (i.e., security services applied or required, or no security) should be identified. A big–data security mechanism based on fully homomorphic encryption using cubic spline curve public key cryptography. This article examines privacy and security in the big data paradigm through proposing a model for privacy and security in the big data age and a classification of big data-driven privacy and security. In case encryption is needed, it will be supported at nodes using appropriate encryption techniques. Authentication: some big data may require authentication, i.e., protection of data against modification. The growing popularity and development of data mining technologies bring serious threat to the security of individual,'s sensitive information. The simulations were conducted using the NS2 simulation tool (NS-2.35). We also have conducted a simulation to measure the big data classification using the proposed labeling method and compare it with the regular method when no labeling is used as shown in Figure 8. “Big data” emerges from this incredible escalation in the number of IP-equipped endpoints. Total Downloads: 24; Authors : Loshima Lohi, Greeshma K V; Paper ID : IJERTCONV4IS06016; Volume & … The MPLS header is four bytes long and the labels are created from network packet header information. Daily tremendous amount of digital data is being produced. The GMPLS/MPLS network is terminated by complex provider Edge routers called here in this work Gateways. In general, big data are collected in real time, typically running into the millions of transactions per second for large organizations. However, the algorithm uses a controlling feedback for updating. Special Collection on Big Data and Machine Learning for Sensor Network Security To have your paper considered for this Special Collection, submit by October 31, 2020. The core idea in the proposed algorithms depends on the use of labels to filter and categorize the processed big data traffic. The Gateways are responsible for completing and handling the mapping in between the node(s), which are responsible for processing the big data traffic arriving from the core network.
