Trusted CI webinar: Identifying Vulnerable GitHub Repositories in Scientific Cyberinfrastructure: An Artificial Intelligence Approach
No full textThe scientific cyberinfrastructure community heavily relies on public internet-based systems (e.g., GitHub) to share resources and collaborate. GitHub is one of the most powerful and popular systems for open source collaboration that allows users to share and work on projects in a public space for accelerated development and deployment. Monitoring GitHub for exposed vulnerabilities can save financial cost and prevent misuse and attacks of cyberinfrastructure. Vulnerability scanners that can interface with GitHub directly can be leveraged to conduct such monitoring. This research aims to proactively identify vulnerable communities within scientific cyberinfrastructure. We use social network analysis to construct graphs representing the relationships amongst users and repositories. We leverage prevailing unsupervised graph embedding algorithms to generate graph embeddings that capture the network attributes and nodal features of our repository and user graphs. This enables the clustering of public cyberinfrastructure repositories and users that have similar network attributes and vulnerabilities. Results of this research find that major scientific cyberinfrastructures have vulnerabilities pertaining to secret leakage and insecure coding practices for high-impact genomics research. These results can help organizations address their vulnerable repositories and users in a targeted manner.

Developing Proactive Cyber Threat Intelligence from the Online Hacker Community: A Computational Design Science Approach
No full textThe proliferation of information systems (IS) has afforded modern society with unprecedented benefits. Unfortunately, malicious hackers often exploit these technologies for cyberwarfare, hacktivism, espionage, or financial purposes, costing the global economy over $450 billion annually. To combat this issue, many organizations develop Cyber Threat Intelligence, or knowledge about key hackers and emerging threats. Despite CTI’s value experts note that existing approaches are reactive in nature. Thus, cyber-attacks remain on an unfortunate uptick. CTI experts have suggested studying the international and ever-evolving online hacker community to address these concerns. However, online hacker community platforms, specifically forums, contain tens of thousands of unstructured, un-sanitized text records. Existing CTI analytics and behavioral and economic methodologies employed in extant IS cybersecurity inquiries were not designed for such data characteristics.
This dissertation presents four essays that adopt the design science approach to develop a series of novel CTI computational IT artifacts to solve a salient CTI issues. Essay I sets the foundation by developing a novel data and text mining framework to automatically extract and categorize malicious hacker exploits. Essay II expands upon this by automatically linking exploits and vulnerabilities detected by modern vulnerability scanners with a novel algorithm, the Exploit-Vulnerability Deep Structured Semantic Model. Essay III leverages graph convolutional networks and autoencoders to develop a novel deep learning architecture to identify the hackers and communities. Essay IV extends the model presented in essay III to identify emerging hacker exploits. Beyond the practical contributions provided by the presented IT artifacts, this dissertation offers numerous design principles to guide future computational cybersecurity IS research and other analytics related research inquiries
SAGAR (Security and Growth for All in the Region) and IPOI (Indo-Pacific Oceans Initiative): Shaping India's Security Through Regional Development
No full textThe world system is undergoing a period of transformation and refragmentation, the disintegration of a single political space into spheres of infl uence formed by the great powers. India, which forms such a sphere around itself, is faced with the problem: a serious economic and military lag behind China, trying, following the ideasof the Indian elites, to achieve hegemony in Southeast and South Asia and the Indian Ocean region. To fend off these attempts, India has put forward two concepts: Security and Growth for All in the Region (SAGAR) and the Indo-Pacifi c Oceans Initiative (IPOI). The article is devoted to the analysis of the problems that New Delhi is trying to solve with the help of these concepts, and the consideration of the very process of their implementation. The author notes that both SAGAR and IPOI are not developed strategic documents, but a type of ‘vision’ typical for Indian foreign policy discourse. At the same time, the active assistance provided by India to the countries of the Indian Ocean region within the framework of SAGAR demonstrates that Indiaperceives these countries as part of its sphere of infl uence and is trying to tie them to itself both politically and economically. On the contrary, the concept of ITOI aims to form partnerships and informal alliances with ASEAN countries and Australia. The author believes that Indian regional concepts are of interest to Russia, allowing it to use the Indian experience and to participate in Indian initiatives
Manufacturing of glass-fiber-reinforced dicyclopentadiene-matrix composites via frontal polymerization
No full textThe student, Sagar Ketan Vyas, accepted the attached license on 2020-03-05 at 10:28.A homogenized reaction-diffusion model is used to study the mechanism of frontal polymerization in glass-fiber-reinforced dicyclopentadiene-matrix composites by studying the effects of the material properties of the reinforcing phase on the velocity, temperature, and width of the reaction front. This model is also nondimensionalized and expressed in a general form in terms of two nondimensional parameters dependent on the material properties and cure kinetics of the composite system. The general nature of this formulation is exploited to generate a large dataset of reaction front velocities for resin chemistries that are similar to dicyclopentadiene (DCPD), which serves as the reference resin in this work. Finally, the homogenized reaction-diffusion model is used to investigate the temperature spike that occurs when two reaction fronts merge. A method to estimate the energy associated with the thermal spike is developed and applied to size a metal heat sink introduced to eliminate the thermal spike.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2022-05-01The student, Sagar Ketan Vyas, submitted this Thesis for approval on 2020-03-05 at 11:12.This Thesis was approved for publication on 2020-03-09 at 16:11.DSpace SAF Submission Ingestion Package generated from Vireo submission #14886 on 2020-08-25 at 17:26:55Made available in DSpace on 2020-08-26T23:51:24Z (GMT).
