Secure Server-Aided Top-K Monitoring, Yujue Wang, Hwee Hwa Pang, Yanjiang Yang, Xuhua Ding

Research Collection School Of Computing and Information Systems

In a data streaming model, a data owner releases records or documents to a set of users with matching interests, in such a way that the match in interest can be calculated from the correlation between each pair of document and user query. For scalability and availability reasons, this calculation is delegated to third-party servers, which gives rise to the need to protect the integrity and privacy of the documents and user queries. In this paper, we propose a server-aided data stream monitoring scheme (DSM) to address the aforementioned integrity and privacy challenges, so that the users are able to …

Towards Secure Data Flow Oriented Multi-Vendor Ict Governance Model, Lars Magnusson, Patrik Elm, Anita Mirijamdotter

UBT International Conference

Today, still, ICT Governance is being regarded as a departmental concern, not an overall organizational concern. History has shown us that implementation strategies, which are based on departments, results in fractional implementations leading to ad hoc solutions with no central control and stagnation for the in-house ICT strategy. Further, this recently has created an opinion trend; many are talking about the ICT department as being redundant, a dying out breed, which should be replaced by on-demand specialized external services. Clearly, the evermore changing surroundings do force organizations to accelerate the pace of new adaptations within their ICT plans, more vivacious …

Analysis Of Security In Big Data Related To Healthcare, Isabel De La Torre, Begoña García-Zapirain, Miguel López-Coronado

Journal of Digital Forensics, Security and Law

Big data facilitates the processing and management of huge amounts of data. In health, the main information source is the electronic health record with others being the Internet and social media. Health-related data refers to storage in big data based on and shared via electronic means. Why are criminal organisations interested in this data? These organisations can blackmail people with information related to their health condition or sell the information to marketing companies, etc. This article analyses healthcare-related big data security and proposes different solutions. There are different techniques available to help preserve privacy such as data modification techniques, cryptographic …

Security And The Transnational Information Polity, Michael M. Losavio, Adel Said Elmaghraby

Journal of Digital Forensics, Security and Law

Global information and communications technologies create criminal opportunities in which criminal violation and physical proximity are decoupled. As in all our endeavors, the good become the prey of the bad. Murderous and venal exploitation of ICT has followed from the inception of the Internet, threatening all the good it brings and the trust we need so badly as a people. As the work continues to expand the implementation of Smart Cities and the Internet of Things, there will be more opportunities for exploitation of these technologies. We examine the social and liberty risks our data and technology-driven responses may entail.

Breaking Into The Vault: Privacy, Security And Forensic Analysis Of Android Vault Applications, Xiaolu Zhang, Ibrahim Baggili, Frank Breitinger

Electrical & Computer Engineering and Computer Science Faculty Publications

In this work we share the first account for the forensic analysis, security and privacy of Android vault applications. Vaults are designed to be privacy enhancing as they allow users to hide personal data but may also be misused to hide incriminating files. Our work has already helped law enforcement in the state of Connecticut to reconstruct 66 incriminating images and 18 videos in a single criminal case. We present case studies and results from analyzing 18 Android vault applications (accounting for nearly 220 million downloads from the Google Play store) by reverse engineering them and examining the forensic artifacts …

Problems In Graph-Structured Modeling And Learning, James Atwood

Doctoral Dissertations

This thesis investigates three problems in graph-structured modeling and learning. We first present a method for efficiently generating large instances from nonlinear preferential attachment models of network structure. This is followed by a description of diffusion-convolutional neural networks, a new model for graph-structured data which is able to outperform probabilistic relational models and kernel-on-graph methods at node classification tasks. We conclude with an optimal privacy-protection method for users of online services that remains effective when users have poor knowledge of an adversary's behavior.

Cyber Security For Everyone: An Introductory Course For Non-Technical Majors, Marc J. Dupuis

Journal of Cybersecurity Education, Research and Practice

In this paper, we describe the need for and development of an introductory cyber security course. The course was designed for non-technical majors with the goal of increasing cyber security hygiene for an important segment of the population—college undergraduates. While the need for degree programs that focus on educating and training individuals for occupations in the ever-growing cyber security field is critically important, the need for improved cyber security hygiene from the average everyday person is of equal importance. This paper discusses the approach used, curriculum developed, results from two runs of the course, and frames the overall structure of …

Malware Analysis And Privacy Policy Enforcement Techniques For Android Applications, Aisha Ibrahim Ali-Gombe

University of New Orleans Theses and Dissertations

The rapid increase in mobile malware and deployment of over-privileged applications over the years has been of great concern to the security community. Encroaching on user’s privacy, mobile applications (apps) increasingly exploit various sensitive data on mobile devices. The information gathered by these applications is sufficient to uniquely and accurately profile users and can cause tremendous personal and financial damage.

On Android specifically, the security and privacy holes in the operating system and framework code has created a whole new dynamic for malware and privacy exploitation. This research work seeks to develop novel analysis techniques that monitor Android applications for …

Lightweight Three-Factor Authentication And Key Agreement Protocol For Internet-Integrated Wireless Sensor Networks, Qi Jiang, Sherali Zeadally, Jianfeng Ma, Debiao He

Information Science Faculty Publications

Wireless sensor networks (WSNs) will be integrated into the future Internet as one of the components of the Internet of Things, and will become globally addressable by any entity connected to the Internet. Despite the great potential of this integration, it also brings new threats, such as the exposure of sensor nodes to attacks originating from the Internet. In this context, lightweight authentication and key agreement protocols must be in place to enable end-to-end secure communication. Recently, Amin et al. proposed a three-factor mutual authentication protocol for WSNs. However, we identified several flaws in their protocol. We found that their …

Are The Trade-Offs For Reducing Cross-Border Cybercrime Manageable?, Steven Mark Miller, Qiu-Hong Wang, Robert John Kauffman

Research Collection School Of Computing and Information Systems

Without increased government intervention andgovernment-industry collaboration, the advantages inherent in the next wave ofInternet-enabled digital transformation will increasingly tilt towardcyber criminals, and their influence will disproportionately increase. The dilemma that immediately presents itself in such ascenario, however, is that an increased level of government involvement canalso lead to undesirable consequences. Increasing security always comes withtrade-offs that must be managed. The obvious concerns relate to the erosion ofprivacy, illegal or extralegal persecution, the abuse of Internet censorshipand the impediment to or stifling of innovation.

Ancient Worries And Modern Fears: Different Roots And Common Effects Of U.S. And Eu Privacy Regulation, David Thaw, Pierluigi Perri

Articles

Much legal and technical scholarship discusses the differing views of the United States and European Union toward privacy concepts and regulation. A substantial amount of effort in recent years, in both research and policy, focuses on attempting to reconcile these viewpoints searching for a common framework with a common level of protection for citizens from both sides of Atlantic. Reconciliation, we argue, misunderstands the nature of the challenge facing effective cross-border data flows. No such reconciliation can occur without abdication of some sovereign authority of nations, that would require the adoption of an international agreement with typical tools of international …

Assessment Of Security Vulnerabilities In Wearable Devices, Brian Cusack, Bryce Antony, Gerard Ward, Shaunak Mody

Australian Information Security Management Conference

Wearable devices have proliferated in usage and human experience, and they provide convenience for personal information requirements. These devices are both sensory and immersive for the diverse global network that is generally termed the Internet of things (IoT). The immediacy of the two-way communication created in the IoT has made vulnerable human behaviour and raised debate around information ownership and privacy expectations. The legitimacy of ownership of information and its reuse are prevalent problems. In this research, we tested four wearable devices that share 44% of the current market, for security vulnerabilities. We found serious weaknesses that could result in …

Cybersecurity Stovepiping, David Thaw

Articles

Most readers of this Article probably have encountered – and been frustrated by – password complexity requirements. Such requirements have become a mainstream part of contemporary culture: "the more complex your password is, the more secure you are, right?" So the cybersecurity experts tell us… and policymakers have accepted this "expertise" and even adopted such requirements into law and regulation.

This Article asks two questions. First, do complex passwords actually achieve the goals many experts claim? Does using the password "Tr0ub4dor&3" or the passphrase "correcthorsebatterystaple" actually protect your account? Second, if not, then why did such requirements become so widespread? …
