Network attack graphs are a type of analysis tool that can be used to determine the impact that security vulnerabilities have on the network. It is important, then, for attack graphs to be able to represent enough information to aid this analysis. Moreover, they must be able to handle and integrate new vulnerabilities that are being discovered by the security community. We developed a prototype tool...
Many of today's machine learning (ML) systems are composed by an array of primitive learning modules (PLMs). The heavy use of PLMs significantly simplifies and expedites the system development cycles. However, as most PLMs are contributed and maintained by third parties, their lack of standardization or regulation entails profound security implications. In this paper, for the first time, we demonstrate...
Compared with other areas, knowledge management in education area has been lack of attention for a long time. This paper did a survey on undergraduate in a Chinese research university. By designing the questionnaire, implementing the survey website by programming, we got 515 original data from art students and science students. Then we analyzed the data by several data-mining algorithms, e.g. the...
The requirement and expanding needs of bridging the physical and cyber world promote the emergence of a new global internet-based information architecture, the Internet of Things. The main challenge in Internet of Things is how to make fast and accurate decisions based on multi-modal sensing data. In this paper, we put human into the process and formulate a closed-loop computing paradigm for IoT data...
System-call analysis is recognized as one of the most promising approaches to malware detection due to its ability to facilitate detection of malware variants as well as zero-day malware. However, one of the key challenges of system-call based analysis - which prevents it from being used in real-time detection systems - is the excessive size/dimensionality of the system-call sequences that correspond...
Scripts have been used in different disciplines to characterize how individuals conceptualize the conduct of goal-oriented tasks. Cornish introduced this modelling approach to the field of environmental criminology as a more systematic way to identify offenders’ decisions during the commission of crime. Despite the growing number of articles about crime scripts, there is limited information about...
This paper presents a new approach to predictive data analytics, called Radius of Neighbors (RN), and its mobile application, a multilingual RN-Chatter, devoted to improve communication among people, speaking different languages. RN is a modeless method of unsupervised machine learning, what makes it a fairly simple but effective way of analyzing big amounts of data while keeping acceptable speed...
Graph structures are often used for representingdata object and link between them in large datasets. Knowledge extraction from these data relies on finding the connected components within these graphs. Given a large graph G = (V, E), where V is the set of vertices and E is the set of edges, the problem is to find the connected components efficiently. The problem offinding the connected components...
A concise and practical introduction is given on Online Social Networks (OSN) and their application in law enforcement, including a brief survey of related work. Subsequently, a tool is introduced that can be used to search OSN in order to generate user profiles. Both its architecture and processing pipeline are described. This tool is meant as a flexible framework that supports manual foraging (and...
Ad-hoc networks are collection of self-organized, autonomous nodes (routers) and capable to communicate directly with neighbors' node through broadcast packet in within transmission range. Ad hoc network has a primary concern to provide protected communication between mobile nodes. In transmission channel, nodes can be a malicious node and compromise or breaches service, which makes security extremely...
The present paper proposes a novel method for grayscale image steganography which provides minimal distortion. The cover image is first divided into some blocks such that each block contains three pixels. Three bits of secret data are then embedded into each block by increasing/decreasing one pixel or rarely three pixels by one as done in LSB matching. However, data bits are not directly extracted...
Secure multiparty computation allows multiple parties to participate in a computation. SMC (secure multiparty computation) assumes n parties where n>1. All the parties jointly compute a function. Privacy preserving data mining has become an emerging field in the secure multiparty computation. Privacy preserving data mining preserves the privacy of individual's data. Privacy preserving data mining...
Quality of Service (QoS) play very important role in web service recommendation system. The precision of service recommendation depends on the credible QoS. So people begin to find better method for calculating the credibility of QoS. We can count the execution result and user comment to calculate the QoS credibility of single web service. But how to calculate the QoS credibility of web service composition...
This paper proposes a steganography method using the digital images. Here, we are embedding the data which is to be secured into the digital image. Human Visual System proved that the changes in the image edges are insensitive to human eyes. Therefore we are using edge detection method in steganography to increase data hiding capacity by embedding more data in these edge pixels. So, if we can increase...
In this paper we present a fast, interactive method for collecting structural primitives from objects of interest contained within manually selected image regions. The input image is projected onto a Max-Tree and Min-Tree structure from which a pixel-to-node mapper marks the nodes of each tree that correspond to peak components explicitly contained within the selected window. In a pass through the...
For the important role of packets in the network management and security applications, many researches have been applied to network packet. How to record and store the packets in an efficient structure is a problem in this field. This paper focuses on the study of network packet tagging technique. Based on existing research, this paper presents a tagging method using the attributes of data stream...
General network attack graph has a large state space. It affects the efficiency of network attack graph generation greatly. In order to solve this problem, a reverse search based network attack graph generation method is proposed. It starts from the target hosts that the goal of attackers, by analyzing the vulnerabilities and connectivity of them, finds all the middleman hosts, then repeats the search...
Grid is the next generation of Internet, and it has attracted the attentions of research communities recently. In practical applications, the nodes in the grid domain need to transact with other strange nodes to acquire the services provided by those nodes. Recently, trust has been recognized as an important factor for Grid security. And it is important for them to make a trust evaluation for those...
SOA have been deployed as a mean to offer a better flexibility, to increase efficiency through reuse of services and also to improve interoperability by providing new opportunities to connect heterogeneous platforms. However, those benefits make security more difficult to control. Fortunately, new standards are proposed to treat this issue, but their current use makes the architecture much more complex...
Service creation by composing existing services and/or network resources is considered by Telecom and Internet industries as the trend for service provisioning in next generation networks. Related research work is being carried out for years, and various service composition approaches have been proposed by different standardization organizations and companies catering to different network requirements...
