Crawling web applications is important for indexing, accessibility and security assessment. Crawling traditional web applications is an old problem, for which good and efficient solution are known. Crawling Rich Internet Applications (RIA) quickly and efficiently, however, is an open problem. Technologies such as AJAX and partial Document Object Model (DOM) updates only make the problem of crawling RIA more time consuming to the web crawler. One way to reduce the time to crawl a RIA is to crawl a RIA in parallel with multiple computers. Previously published Dist-RIA Crawler presents a distributed breath-first search algorithm to crawl RIAs. This paper expands Dist-RIA Crawler in two ways. First, it introduces an adaptive load-balancing algorithm that enables the crawler to learn about the speed of the nodes and adapt to changes, thus better utilize the resources. Second, it present a distributed greedy algorithm to crawl a RIA in parallel, called GDist-RIA Crawler. The GDist-RIA Crawler uses a server-client architecture where the server dispatched crawling jobs to the crawling clients. This paper illustrates a prototype implementation of the GDist-RIA Crawler, explains some of the techniques used to implement the prototype and inspects empirical performance measurements. © 2014 Springer international Publishing.

There has been significant interest in the identification and profiling of insider threats, attracting high-profile policy focus and strategic research funding from governments and funding bodies. Recent examples attracting worldwide attention include the cases of Chelsea Manning, Edward Snowden and the US authorities. The challenges with profiling an individual across a range of activities is that their data footprint will legitimately vary significantly based on time and/or location. The insider threat problem is thus a specific instance of the more general problem of profiling complex behaviours. In this paper, we discuss our preliminary research models relating to profiling complex behaviours and present a set of experiments related to changing roles as viewed through large-scale social network datasets, such as Twitter. We employ psycholinguistic metrics in this work, considering changing roles from the standpoint of a trait-based personality theory. We also present further representations, including an alternative psychological theory (not trait-based), and established techniques for crime modelling, spatio-temporal and graph/network, to investigate within a wider reasoning framework. © 2014 Springer international Publishing.

In this paper, we address the problem of formal security verification of transport protocols for wireless sensor networks (WSN) that perform cryptographic operations. Analyzing this class of protocols is a difficult task because they typically consist of complex behavioral characteristics, such as launching timers, performing probabilistic behavior, and cryptographic operations. Some of the recently published WSN transport protocols are DTSN, which does not include cryptographic security mechanism, and two of its secured versions, SDTP and STWSN1. In our previous work, we formally analyzed the security of distributed Transport for Sensor networks (DTSN) and distributed Transport Protocol for Wireless Sensor networks (SDTP), and showed that they are vulnerable against packet modification attacks. In another work we proposed a new Secure Transport Protocol for WSNs (STWSN), with the goal of eliminating the vulnerability of DTSN and SDTP, however, its security properties have only been informally argued. In this paper, we apply formal method to analyze the security of STWSN. © Springer international Publishing Switzerland 2014.

Intrusion Detection systems (IDS) are becoming an essential component usually in network and data security weapon store. Since huge amount of existing off-line data and newly appearing network records that needs analysis, data mining techniques play a vital role in development of IDS. The key idea of using data mining techniques for IDS is to aim at taking benefit of classification capability of supervised learning based neural networks and clustering abilities of unsupervised learning based neural networks. In this paper, we propose an efficient intrusion detection model by amalgamating competent data mining techniques such as K-means clustering, Multilayer layer perception (MLP) neural network and support vector machine (SVM), which significantly improve the prediction of network intrusions. Since the number of clusters desired for intrusion detection problem is defined by user a priori and does not change, we employed K-means clustering technique. In the final stage, SVM classifier is used as it produces superior results for binary classification while compared to the other classifiers. We have received the best results and these are compared with results of other existing methods to prove the effectiveness of our model. © Springer international Publishing Switzerland 2014.

In big data environment, hadoop stores the data in distributed file systems called hadoop distributed file system and process the data using parallel approach. When the cloud users store unstructured data in cloud storage, it becomes very important for cloud providers to secure those data. To provide malware security, cloud service providers should scan the whole contents of the database, which is a very time intensive job. It may even take days to complete the tasks. The main aim of the proposed work is to reduce the processing time by introducing Graphics Processing Unit (GPU) in hadoop cluster. The proposed work integrates two text pattern matching algorithms with the map-reduce programming model for faster detection of malware in big data. The results of our study indicate that use of GPU decreases the processing time of text pattern matching algorithms in big data hadoop. © Springer international Publishing Switzerland 2014.

Due to limited energy and physical size of the sensor nodes, the conventional security mechanisms with high computation complexity are not feasible for wireless sensor networks (WSNs). In this paper, we propose a compressive sensing-based encryption scheme for WSN, which provides both signal compression and encryption guarantees, without the additional computational cost of a separate encryption protocol. We also show that, for proposed WSN, if only a fraction of randomizer bits is stored by an eavesdropper, then he/she cannot obtain any information about the plaintext. WSNs usually are deployed in a hostile environment and left unattended, which could be compromised by the eavesdropper. Numerical results show that there is a trade-off between the number of sensor nodes required to reconstruct the original data and the approximation error in both normal and attack conditions. The approximation error of data decreases when less sensor nodes are compromised by the eavesdropper. © 2014 Springer international Publishing Switzerland.

With the explosion of data in the past decade, big data is becoming a research hotspot in the information field. Many cloud-based distributed data processing platforms have been proposed to provide efficient and cost effective solutions for big data query processing, such as Hadoop, Hive, Pig, etc. However, most of the current research works are focus on improving the performance of query processing based on the view of systematics while without considering the characteristics of queries themselves, such as the query similarity, which will cause large numbers of redundant computation, effect query execution efficiency, thus having an adverse impact on promotion of the multi-queries processing performance. To solve this problem, in this paper, we propose a Multi-queries optimization framework based on MapReduce-oriented cloud environment (Multi-Q), which utilizes the dependence between multiple queries to realize query results reuse. Firstly, a cluster-based partition algorithm called CPA has been exploited to conduct the logic partition of the search range of query workload. Secondly, a multi-queries reuse dependence graph (MRDG) construction method on the basis of the cluster-based partition results has been presented to depict the dependence between the multiple queries. Finally, a Multi-Q processing algorithm based on Multi-Q Reuse Dependence Graph has been put forward to achieve the query results reuse and improve the overall query processing performance. We evaluate our approach by deploying Multi-Q based on Hadoop in a real cloud environment, called SEU-Cloud, and conducting extensive experiments based on the standard TPC-H. The result verifies that compared with Hive, the performance of improvement is approximately 39.3% by using our Multi-Q. © 2014 IEEE.

In spite of extensive research on WSN for decades, it still has not slowed down in pace. Newer technologies like Internet of Things which focuses on detail information, WSN sought to be an integral part of this. In this paper, we tried to illustrate the study that had been done for better research possibilities and opening up newer concepts. We discussed from very basic parts of a WSN network to real life implementation on some advance stage. We studied the efficient reconfigurable security approach for Wireless Sensor networks (WSN) with XBee and Arduino. The users can reconfigure the security scheme and algorithms by reloading the program in sensor node with a programmable processor. We tested our system with RC4 stream cipher and modified RC4-Based Hash function to provide the security services.
