SUMMARY:Durga Suresh PhD Proposal Review
DESCRIPTION:Title: Network Security Management and Threat Mitigation in the Open Cloud\n \nCommittee Members:\nProf. Miriam Leeser (Advisor)\nProf. Michael Zink\nProf. Xiaolin Xu \nAbstract:\nCloud computing and advanced cyberinfrastructures are increasingly vital to the functioning of Internet systems. Every day\, more devices are added to the cloud\, to provide greater resource utilization\, availability\, and scalability. Due to the expanding reliance on cloud computing\, securing the cloud is paramount. Tackling the issue of securing the cloud is crucial not only for preserving the functionality and reliability of cloud-based systems but also for protecting the critical data and services that depend on these platforms. \nCloud computing models include public clouds\, private clouds\, community clouds\, and hybrid clouds. Private\, community\, and hybrid clouds provide security\, but with an important trade-off; namely\, user access restriction in the cloud. The proposed research uses the Open Cloud Testbed (OCT) which is part of the National Science Foundation’s (NSF) Computer and Information Systems Engineering(CISE) Community Research Infrastructure(CRI) program. OCT is an example of a public cloud that allows users two things: 1) an isolated set of nodes to perform experiments with bare metal access\, which can potentially lead to security issues\, and 2) the ability to test out the solutions for both using the cloud and adding security to it. The proposed research aims to target a system like the OCT\, specifically targeting a public cloud environment. \nThis system will be designed to allow access to the switch\, enabling control and management of traffic within the cloud network. This research aims to mitigate network security threats in the public cloud network. The aim of this research is multifold. First\, we identify and classify the behavior of users in the cloud. We then provide an approach to creating a network security management policy that will deal with 1)detecting network intruders that scan the cloud network and remove their access to the network\, and  2) managing heavy hitters that can cause Denial of Service (DOS) and Distributed Denial of Service (DDOS) attacks in the cloud network by using the heavy hitter detection system and prevent them from putting more traffic on the network. Both network intruder detection and heavy hitter management systems use Access Control Lists (ACL)as a means to prevent the user from putting traffic on the cloud network. Lastly\, we perform experiments to handle these threats and measure the success of the experimental setup concerning network attacks. The proposed approach will ensure network security by creating a framework for network security management policy to minimize threats in the cloud network and other resources directly attached to the network. The proposed research aims to enhance cybersecurity by employing network intruder detection techniques to identify potential threats\, implementing heavy hitter management to mitigate threats effectively\, and developing and enforcing a network security management policy to prevent future threats.

SUMMARY:Deepak Prabhala MS Thesis Defense
DESCRIPTION:Title: “Smart Microwave Devices with Programable Printed Circuit Board (PPCB): Design with Liquid Crystal Elastomer Polymers in Transmission Lines and Circulators” \nCommittee Members:\n1) Professor Nian X. Sun (Advisor)\n2) Professor Marvin Onabajo\n3) Professor Yongmin Liu \nAbstract:\nThis study explores the innovative application of liquid crystal elastomer (LCE) polymers in the design and implementation of microwave transmission lines and circulators. Liquid crystal elastomers\, known for their unique combination of liquid crystalline and elastomeric properties\, offer a unique approach to developing flexible and tunable microwave devices. The research focuses on a thorough study of the electro-mechanical properties of LCEs to achieve novel functionalities in the design of transmission lines and circulators for microwave communication systems in HFSS simulations. The first part of the study delves into the characterization of the dielectric and mechanical properties of the chosen LCE polymer. Subsequently\, the design and fabrication of a flexible and tunable transmission line using LCE are discussed. The LCE-based transmission line aims to measure the insertion loss and return loss with different widths\, lengths\, and thicknesses of the LCE polymer. The study investigates the impact of temperature on the transmission line’s performance\, offering insights into potential applications in reconfigurable microwave systems. The second phase of the research explores the utilization of LCE in the development of a microwave circulator\, a vital component in microwave communication networks. The circulator design incorporates the unique properties of LCE by using a stepped dielectric variation approach for broadband isolation. This innovation holds promise for enhancing the efficiency and adaptability of microwave systems in communication and radar applications. The findings of this research contribute to offering a pathway for integrating liquid crystal elastomers into flexible and reconfigurable microwave devices. This thesis aims to advance the understanding of smart microwave devices and inspire further exploration into the application of liquid crystal elastomer polymers in cutting-edge technologies.
