Reality of the Homeland Security Enterprise Information Sharing Environment
From the thesis abstract: "Responding to recommendations from the 9/11 Commission, Congress created the Information Sharing Environment (ISE) with the passage of the 2004 Intelligence Reform and Terrorism Prevention Act. Linked to the creation of the Office of the Director of National Intelligence and championed by that office's program manager for the ISE, the ISE has contributed to national intelligence reform by attempting to improve information sharing across the federal, state, local, territorial, and tribal domains. Given the rise in domestic terrorist attacks and the progress of intelligence reform over the last 16 years, this thesis explores an analysis of the ISE's effectiveness and an examination of alternative means of information sharing to address the remaining information-sharing challenges brought to light in attacks carried out between 2014 and 2017. Alternative information-sharing techniques have been used by our nation's special operations forces and by our largest police force, the New York Police Department. The best practices of organizations such as these may be leveraged by the ISE to further future intelligencesharing reform."

Role of Mental Illness Identification and Screening in Firearm Background Checks
From the thesis abstract: "Highly publicized mass shootings, and often the corresponding commentary on the perpetrator's mental health, lead many to question how such a person could have acquired access to a firearm. Mental illness, broadly speaking, is a prohibiting criterion for individuals to purchase a firearm, yet there are several examples of individuals who have a history of mental illness and are able to legally pass a firearm background check. This thesis examines the tenuous relationship between mental illness and violence, and evaluates federal and state laws to assess the prohibited criteria. Individuals with mental illness who go untreated and have co-occurring disorders are at an increased risk of violence, yet may never enter into the courts or are not involuntarily committed to a mental institution. This research concluded, therefore, that statutes need to change by placing less emphasis on involuntary commitment to mental institutions and instead adopt a risk-based approach that restricts firearm access by individuals with a mental illness who may present a risk of violence once they are identified. Legal, procedural, and clinical implications are explored to ensure that individuals' Constitutional rights are protected while mitigating risk and maintaining a primary goal of ensuring effective treatment."

Proposed Cosmology of Identity in the Sociotechnical Ecosystem of Homeland Security
From the thesis abstract: "This thesis explores how identity and technology interact in the context of terrorism and conflict. This relationship is important to understand because technology can be designed to shape identity and drive behavior. This ability to manipulate identity through technological means has ethical implications for technological innovation and design and can lead to emerging threats in homeland security. This thesis uses the position of soldier as a template to develop an understanding of the most basic social functions, which are technologically dependent. Following the analysis, the thesis builds a framework called the sociotechnical ecosystem based on artifact, mobility, communications, information, and network structures. Finally, this thesis proposes a new conceptual model to provide a mechanism for analyzing the influence a technological environment can exert on social identity."

Insider Threat to Cybersecurity: How Group Process and Ignorance Affect Analyst Accuracy and Promptitude
From the dissertation abstract: "The recent increase in high-profile insider cyber exploits indicates that current insider threat analysis (ITA) is insufficient to handle the growing insider threat problem. Well-established academic literature agrees that information overload is a problem ITA must overcome because ITA remains a human-intensive task. Two conceptual strategies to overcome information overload include reducing information and distributing information among additional people to accommodate the load. This dissertation applies attribution theory and process loss theory to test two ITA factors: ignorance and teamwork. A laboratory experiment with a convenience sample of 48 ITA-trained, top secret-cleared participants supported the research. Participants performed ITA with National Insider Threat Task Force training scenarios and applied the adjudicative guidelines for access to classified information. Teamwork conditions resulted in slightly higher accuracy at a significant cost of time, indicating that ITA analysts are best organized in different structures per informational and temporal constraints. However, ignorance level had little effect on ITA analyst accuracy. ITA analysts were substantially more accurate at implication scenarios but slightly better than chance at exoneration scenarios. Lower decision confidence associated with exoneration scenarios indicated that ITA analysts are more likely to guess when presented with an exoneration scenario. Further research involving larger independent samples and temporal constraints is necessary to verify these findings."

Recruiting the Cyber Leader: An Evaluation of the Human Resource Model Used for Recruiting the Army's 'Cyber Operations Officer'
From the thesis abstract: "For the first time since the creation of the Special Forces branch in 1987, the Army authorized the creation of a new branch, the Cyber branch. With this, the Army joined the ranks of other organizations in this rapidly expanding arena. The Army found itself in a situation where it needed to quickly fill the positions required of this new branch. To accomplish this goal the Army developed a recruitment strategy based on the Army human resource management model. The purpose of our research is to evaluate the effectiveness of that model to recruit Cyber Operations Officers and to examine the effects of its continued use. To perform this evaluation we conduct an operational assessment that included identifying and assessing measures of performance (MOPs) and measures of effectiveness (MOEs) based on data collected from: Army institutions; a survey of the Cyber Branch population; and the Person-Event Data Environment database. Our research also examined recruitment strategies and practices in other selected organizations to identify practical recommendations for improvements to current Army practices. The results of this research suggest that while the Army was generally successful in accomplishing the identified tasks of its recruitment strategy, there were inconsistencies in its application. Additionally, through analysis of the survey data we were able to identify attributes that had the most impact on achieving desired effects. Finally, we found that the Army did not recruit in accordance with best practices for the cyber workforce and that it did not use available tools to measure aptitude in its recruitment and the selection process. We identify some practical implications and provide recommendations for further research in this fast-paced operational environment."

Engineered Resupply System for Humanitarian Assistance and Disaster Relief Operations
From the thesis abstract: "This research examines the effectiveness of resupply systems in humanitarian assistance and disaster relief (HADR) operations by exploring different permutations of operational energy (OE)-focused assets and policies that a Marine Expeditionary Unit (MEU) employs to improve its throughput of resources to disaster victims. The basis for the modeled scenario is the support provided by the 31st MEU to the city of Hachinohe as part of Operation TOMODACHI. This thesis focuses on OE and only considers the medium tactical vehicle replacement (MTVR) as the baseline capability. An agent-based simulation is then used to model the effectiveness of OE-focused resupply strategies and capabilities. These options include (1) efficient driving techniques, (2) reducing idling time, (3) hybrid technologies, and (4) follower vehicles. To investigate their effectiveness, this research uses a design of experiments approach to efficiently examine a set of design factors for specified operational plans. Statistical results indicate that the operational plans employing shorter and quicker vehicle convoys that communicate with one another are most effective in resupplying isolated victims. This research also confirms that the employment of OEfocused assets and policies is effective in increasing timeliness of resupply. Taken together, these factors contribute toward increasing the operational reach of a MEU conducting HADR resupply."

Threshold Shortest Path Interdiction Problem for Critical Infrastructure Resilience Analysis
From the thesis abstract: "We formulate and solve the threshold shortest path interdiction problem, which we define as follows: Find a finite set of arcs to attack within a network such that the resulting shortest path from a given source node to a given destination is longer than a specified threshold. Ultimately we are concerned with determining the number of such attacks and using it as a measure of resilience or lack thereof, in an instance of the shortest-path interdiction problem. We develop and implement algorithms to reduce the required computational effort to solve this counting problem exactly.We illustrate via test cases the impact of different interdiction combinations with regards to the threshold value. Whether these interdictions are random occurrences or intentional, this analysis provides decision makers a tool with which to more completely characterize the resilience of a system of interest."

Drone Defense System Architecture for U.S. Navy Strategic Facilities
From the thesis abstract: "Small, commercially available unmanned aerial systems (UAS) are an emergent threat to Navy continental U.S. (CONUS) military facilities. There are many counter unmanned aerial system (C-UAS) tools focused on neutralization, and many sensors in place. A system-of-systems, defense-in-depth approach to C-UAS requires a central system to connect these new and existing systems. The central system uses data fusion and threat evaluation and weapons assignment (TEWA) to properly address threats. This report follows a systems engineering process to develop a software architecture for that central system, beginning with a requirements analysis, a functional baseline, and the resulting module allocation. A series of simulations in ExtendSim derives the performance requirements by examining the overall C-UAS scenario with currently available technology. Through a sensitivity analysis, the simulation shows that effective engagement range (combination of initial target range, detection range and neutralization range) is the dominant factor driving response time. The architecture modeled in Innoslate provides a discrete event simulation for system performance expectations."

Mission Planning for Heterogeneous Uxvs Operating in a Post-Disaster Urban Environment
From the thesis abstract: "Time is critical during search and rescue operations, as human survival diminishes exponentially if survivors are not located and recovered efficiently. This thesis sought to integrate technologies into a solution that helps rescuers plan for a mission utilizing multiple autonomous unmanned systems (UxV) for search operations. It exploits methods of image analysis to fuse data into a common map and identify key areas of search interest. The key mission areas were developed by comparing edge detection techniques on images obtained from remote sensing platforms in the DigitalGlobe database. Together with close-up snapshots of the environment obtained from drones, three-dimensional maps were developed by stitching the images together into a comprehensive model for a mission commander's use. With the mission bubbles developed, a probabilistic road map was used to develop an optimal trajectory to the search area. It was found that by connecting to the 20 nearest neighboring points in the K-dimensional graph instead of all the points, and using the weighted heuristic method for the A* search, formed the most optimal means to obtain a solution. Together with a tool to generate search patterns for multiple drones, an experiment at Camp Roberts was conducted successfully. Technology was effectively used in the development of a mission-planning tool utilizing a set of heterogeneous unmanned systems for a search mission, which can be expanded for various types of military applications."

Decision Model for U.S.-Mexico Border Security Measures
From the thesis abstract: "The Department of Homeland Security (DHS) has invested billions of dollars to prevent illegal drugs, immigration, weapons, and currency from transiting across the U.S.-Mexico border. DHS has not created a sufficient standardized method to measure whether an investment in a security measure is cost-effective when combining assets. To take it one step further, DHS has not created a model that combines cost-effectiveness of a security asset while simultaneously determining how it will contribute to achieving operational control of the border. This study provides an in-depth look into the current risk-based model DHS uses, the administrative and physical infrastructure of U.S.-Mexico border security, and a critical view of DHS' annual budget. A decision model is presented that will give policymakers a process to choose a combination of border security investments that will achieve operational control of the border while remaining within budgeting constraints. A lot of work needs to be done for DHS to determine the correct security assets to be placed at the U.S.-Mexico Border to maintain operational control and cost-effectiveness. This study does not determine which security assets need to be put into place, but it provides a decision process that will be an asset for policymakers to save federal time and money assigned to border security investments."

Use of VR Technology and Passive Haptics for MANPADS Training System
From the thesis abstract: "Man portable air defense systems (MANPADS) are point-defense weapons that typically form the penultimate layer of defense against aerial threats. Deployed at close ranges to the installation being defended, MANPADS operators get little reaction time to engage attacking aircraft. The situation becomes more complex in a multi-threat scenario such as an airfield under attack. Dealing with such situations requires high proficiency and the capability to make tactical decisions quickly. Live training opportunities allow few operators to fire during live exercises. Simulation training is effective, but customized high-fidelity immersive training facilities are limited. Moreover, low trainee throughput from such high-end facilities is an ongoing obstacle. The main focus of this thesis research is a feasibility study for building a low-cost MANPADS training solution that uses commercial off-the-shelf components. The developed prototype leverages a fully immersive virtual reality system with head-mounted display, game engine, and passive haptics. It provides MANPADS operators with alternative training opportunities in target acquisition, tactical decision making, and situational awareness in a multi-threat scenario, and has the potential of addressing the current training gap. This development experience will provide valuable insights that can be employed to design and create a new generation of low-cost training solutions in other domains as well"

Police Self-Deployment at Critical Incidents: A Wicked Problem or a Part of the Solution?
From the thesis abstract: "incidents, is alternately condemned or hailed as heroism. Confined to response narratives in after-action reports, existing literature provides no comprehensive definition. Without clear principles, it is challenging to prevent the problems produced by self-deployment such as traffic congestion and diminished command and control; nevertheless, encouraging the ingenuity and initiative leading to heroic and lifesaving acts is equally difficult. Many of the descriptions of police self-deployment match characteristics of wicked problems, as proposed by Horst Rittel and Melvin Webber. Using a case study analysis of police responses to the 2013 Christopher Dorner manhunt and 2013 Boston Marathon bombings, this thesis explored police self-deployment through the lens of wicked problems. A better understanding of the definition resulted in policy and training recommendations, including the suggestions that law enforcement embrace, rather than prohibit, self-deployment and that federally mandated incident command policies incorporate the early minutes of a critical event known as the 'edge of chaos.'"

Fortress America: The Aesthetics of Homeland Security in the Public Realm
From the thesis abstract: "Architecture communicates a message about the purpose of a space, the prestige of those who use or own the space, and the values associated with both users and owners. The aesthetics of this architecture elicit specific emotions, communicate histories, and inform worldviews. In the United States, homeland security architecture is largely a physical representation of a perceived threat of a terrorist attack in public spaces. Architecture has sociological, psychological, and cultural effects, as well as security impacts, but there is little research or discourse on the physical manifestation of homeland security in the United States. What are the consequences--intended and unintended--of homeland security architecture? How does a democratic government protect itself and design buildings and public spaces that are open, attractive, and promote both physical and psychological security? This thesis is a starting point for broader awareness and discussion within the emerging discipline of security design about the importance of aesthetics in homeland security."

Preventing Firefighter Exposure Hazards
From the thesis abstract: "This thesis examines detrimental health exposures for firefighters and recommends fire service policy and equipment upgrades designed to slow or eliminate these harmful exposures. Because firefighters are exposed to numerous environmental dangers during their careers, this thesis focuses on eliminating three occupational exposures contributing to health issues: chemical flame retardants, diesel exhaust, and toxins in synthetic furniture. Existing studies written by scholars, consumer advocacy groups, and government agencies identify several exposure hazards and recommend preventive measures to address them. In addition to examining these studies, this thesis reviews a well-intentioned California state law--which allowed chemical flame retardants in home furniture and electronic products--that has caused an exposure hazard for both firefighters and the general public. The thesis also exposes necessary upgrades for firefighters' portable air-supply units to reduce respiratory exposures. Finally, because diesel exhaust emissions have adverse health effects and are abundant in fire stations, the thesis recommends making changes to fire stations to better contain the diesel by-products of the fire trucks, including the possibility of purchasing electric-powered fire trucks to eliminate the diesel engine. Rather than providing a clinical study, this thesis offers an examination of occupational health hazards and recommends mitigative equipment and policy upgrades."

Less is More: North American Case Studies on the Amalgamation of Policing
From the thesis abstract: "American policing is mired in a stratified model of inefficiency involving nearly 12,500 standalone municipal police agencies. The future of policing requires increased participation in cybercrime, transnational crime, terrorism, and infrastructure protection that cannot be accommodated by small standalone police agencies. Canada shares similar experiences in the origins, maturation, social conditions, and opportunities in policing with success in amalgamating police service. This thesis uses comparative case-study research of successful and failed attempts at amalgamating police services in Canada and America. Analysis and recommendations show that amalgamation can best be achieved through large agency contracting, sheriff services, and state policing. Amalgamation to state policing is recommended based on Canadian case studies and American case studies."

Department of Homeland Security's Role in Protecting the National Economy
From the thesis abstract: "The national economy and the vital commercial flows that feed it are the sine quibus non of national influence, power, and security. However, new characteristics of the modern trade environment have the potential to undermine U.S. economic prosperity. The Department of Homeland Security (DHS) claims that homeland security is inseparable from economic security and, as such, that the department has a role to play in supporting national economic security goals. However, DHS has yet to fully reconcile the tension between its trade enforcement and facilitation missions and clarify its role in supporting national economic competitiveness goals. After identifying and assessing several policy alternatives, this paper concludes that DHS should aggressively leverage its unique border authorities to influence a shift toward a more centralized model of government controls of imports, one informed by economy-wide strategic objectives and reliant upon standard performance measures, shared funding schemes, common information technology infrastructures, and delegated decision making on the admissibility of goods. Such an effort could provide commercially meaningful benefits to public and private stakeholders alike while maintaining security and safety requirements."

Inclusion of Disaster Resiliency in City/Neighborhood Comprehensive Plans
From the thesis abstract: "Once hazard mitigation is included in a city's comprehensive plan, the region and its citizens are more prepared to respond to a potential natural disaster. The purpose of this thesis was to illuminate factors that encourage cities to include hazard mitigation within their comprehensive plans. The research used geographic information system (GIS) and census data to locate urban, suburban, and rural areas at risk of flooding and analyzed these regions' comprehensive plans. The research results suggest that previous major flooding events often lead to the inclusion of flood-related hazard mitigation into cities' comprehensive plans. This finding suggests that policy alone does not influence hazard mitigation; other methods should be practiced to ensure hazard mitigation is included within neighborhood/city comprehensive plans."

Leveraging Gamification Techniques and Strategies as a Means of Improving Border Security Data Collection
From the thesis abstract: "Gamification has served as an emerging trend toward engagement and data collection. This thesis seeks to apply the methods and procedures of gamification systems toward the data gathering processes utilized by U.S. Customs and Border Protection (CBP) as part of its maritime border security strategy. It focuses on what makes gamification work, as well as how it can be applied in the e-government sphere toward improving the interaction between the trade and shipping communities with CBP. A review of existing CBP data collection systems and requirements, as well as a study of the organizational strategies, psychologies, and application techniques, point to the feasibility of gamification features toward solutions to concerns regarding motivation, accuracy, and efficiency of persons providing cargo and supply-chain data to CBP. It recommends the implementation of these features into existing CBP maritime data collection programs used by trade entities."

Searching for Effective Training Solutions for Firefighting: The Analysis of Emergency Responses and Line of Duty Death Reports for Low Frequency, High Risk Events
From the thesis abstract: "Since 9/11, the fire service has experienced a shift and an expansion in the nature of threats and hazards that it faces. Despite advances in the field, firefighters are still losing their lives inside of burning buildings, and they must find new ways of identifying training gaps and improving current training practices. This thesis explores whether emergency incidents connected to low frequency and high risk events contain sufficient warning signs or indicators of imminent catastrophic events, if firefighters could identify them, and if there was a potential of changing decision making and averting a tragedy. In order to create a firm basis for this discovery, this research effort included a detailed analysis of the National Institute for Occupational Safety and Health's line of duty death reports from the years 2013- 2015. The work provided an opportunity to learn from past events and practices and identify successes and failures in the firefighting domain without the bias of being closely involved with the cases or having a specific agenda. Quantitative analysis performed on this data set and the knowledge gleaned from looking at the events after the fact provide a foundation for advising novel training approaches and scenarios that can be used to train both individuals and teams of fire fighters."

Strategic Communications: The State Department Versus the Islamic State
From the thesis abstract: "As the battle against the Islamic State unfolds on the battleground and in cyberspace, the U.S. government has declared its commitment to disrupt--and ultimately defeat--the terrorist group. The Islamic State, also known as the Islamic State in Iraq and the Levant and ISIS, has become one of the most deadly and influential terrorist groups in the Middle East. Strategic communications cannot be underestimated. The unit tasked with countering the terrorist group's propaganda and recruitment efforts, the State Department's Center for Strategic Counterterrorism Communications (CSCC), has recently restructured to improve its efforts. This thesis examines the Center's mission, strategy, and communications to assess the efficacy of its efforts to counter the Islamic State terrorist group and degrade its ability to recruit foreign fighters. It analyzes the Islamic State and introduces the CSCC's successor, the Global Engagement Center. Finally, it offers research findings and provides recommendations for future consideration."

Problem-Solving in Homeland Security and Creating Policy Conditions for Enhanced Civic Engagement: An Examination of Crowdsourcing Models
"This thesis examines crowdsourcing experiments and engagement models, the leveraging of technology in these pursuits, and their potential utility for solving problems in the homeland security enterprise. Rather than identifying a gap or seeking to fix something that is 'broken,' the research evaluates the potential benefits of employing crowdsourcing models in homeland security and its related disciplines. It uses appreciative inquiry to evaluate how existing successful models might open new pathways between government and citizens for the generation of knowledge, the exchange of information, or for innovation in approaches to problem solving. This thesis advances the hypothesis that, within the body of crowdsourcing and engagement models, a combination of ideas, examples, approaches, and successes exists that demonstrates potential utility for the homeland security field. The research findings exhibited this potential, manifesting in new partnerships and the creation of new knowledge. Participants, aided only by personal technology, self-organized some initiatives; in other cases, participants simply needed a platform to enable their motivation to contribute. These platforms for engagement and pathways to them were a consistent part of the narrative across the literature. Contributions by the non-professional was also a consistent theme, as was a need for a balanced approach that provides a safe framework within which to operate."

Transparency, Accountability and Engagement: A Recipe for Building Trust in Policing
"Police departments across the nation are challenged to reduce crime, improve quality of life, and, with diminished resources, face the increased threats to homeland security. Many have struggled to find the right balance between keeping communities safe, while at the same time having transparent and effective counterterrorism strategies. This thesis examines the role race plays in policing and the criminal justice system. A comparative analysis was conducted of the New York Police Department's [NYPD] community policing and counterterrorism strategies and that of the United Kingdom's counterpart, the Metropolitan Police Service. The research focuses on how important police legitimacy and transparency are to gaining the trust of the community at large. It also examines how technology and social media can assist in building trust and enhancing accountability. The research concludes with four recommendations, which, if implemented, will move the NYPD toward a more balanced counterterrorism strategy that actively engages with the community it serves."

Cyber Situational Awareness Model for Network Administrators
From the thesis abstract: "Although there are many well-established cyber security tools and techniques available to network administrators for managing and defining their systems, attackers still succeed in penetrating their systems. Defending these systems' confidentiality, integrity, and availability is the responsibility of network administrators; however, protecting these systems becomes more difficult when one considers the volume and velocity of data provided by many of these cyber security tools. Often this data may actually indicate a cyber-attack, but is hard to discern among the bulk of data provided. The purpose of this research is to propose a cyber situational awareness (CSA) model to provide network administrators with better situational awareness of cyber security threats to their systems. This research examines an established situational awareness model and surveys cyber security practices and tools to extend this knowledge to actual cyber situational awareness. This research further develops a model for CSA in three hierarchical levels: configurational awareness, operational awareness, and special conditions awareness. The research concludes that if network administrators manage their systems with awareness of these three levels, they would be able to decrease the amount of unnecessary data and focus on the most important information that can help them better guarantee cyber security of their systems."

Enduring Poverty: Explanations for the Persistence of Minority Poverty in Vietnam
From the thesis abstract: "This thesis examines the persistence of poverty among ethnic minorities in Vietnam. Ethnic minorities are consistently poorer than the Kinh-Hoa majority in Vietnam, having benefitted less from the country's economic growth and targeted government poverty alleviation programs. Why does poverty persist among ethnic minorities despite Vietnam's efforts to improve the wealth and living standards of poor minorities in mountainous and rural areas? This thesis argues that ethnic discrimination and cultural differences between ethnic groups contribute more to the persistence of minority poverty than geography and agricultural livelihoods. When prosperity levels are compared between the ethnic majority and minority groups, between ethnic groups in similar geographic regions, and between ethnic groups with agricultural livelihoods, the result is that minorities are typically poorer than the majority even when both groups live in the same areas and work in the same job sectors. Thus, ethnicity has a greater impact on interethnic inequality and poverty than geography or livelihood. This thesis finds that cultural differences between minority and majority ways of life, social factors of ethnic discrimination, and ethnocentric poverty alleviation programs are the main limiters of the returns to assets and inputs of ethnic minorities in Vietnam."

Lessons Learned from the Development and Implementation of a Knowledge Management Program for the Naval Sea Systems Command
From the thesis abstract: "This study applied knowledge management (KM) theories and principles to develop and implement a KM program for the Naval Sea Systems Command (NAVSEA) that strengthens the workforce's understanding of the technical business processes led by the NAVSEA Chief Engineer. This was accomplished by enabling the transfer of explicit and tacit knowledge that is resident within the NAVSEA enterprise through knowledge flow processes. Research methods employed include a literature review of theoretical knowledge concepts; observation of end-user reactions to developed products and methods of delivery; and continuous evaluation and adjustment in response to demand signals from the workforce. The KM program was designed to accelerate knowledge transfer between personnel of all experience levels, while also encouraging collaboration and facilitating social learning for NAVSEA's Engineering Competency and its stakeholders. Lessons learned throughout this study were applied to shaping the KM program into a diverse set of communication tools that have improved the knowledge base and employee engagement with respect to engineering and technical authority concepts across the NAVSEA enterprise. Although the focal organization supports a military mission, the fundamental elements of this KM program can be replicated and tailored to suit the needs of any organization."

Improving SPAWAR PEP C4I Organizational Alignment to Better Enable Enterprise Technical Risk Management
"This thesis examined how the Navy's Program Executive Office Command, Control, Communications, Computers and Intelligence (PEO C4I) has performed enterprise risk management (ERM). Based on ERM literature, the study developed an analytical framework to assess PEO C4I's ERM practices against documented ERM best practices, including evaluating a new risk in terms of its impact on existing risks and ensuring risks are managed at the most detailed level possible. The thesis also utilized organizational alignment literature to include organizational alignment principles in the evaluation. Key principles include 1) every employee has the responsibility to manage risk and 2) multiple teams are able to manage a single risk. The resultant analytical framework was applied to PEO C4I and documented for application to other organizations. PEO C4I performed well in the areas of 1) evaluating risks in areas other than the originating program office and 2) providing the framework to elevate risks to leadership. PEO C4I could use improvement in cross-team risk coordination and development of enterprise models to provide context for enterprise risks. Recommended interventions focus on having more functional areas involved in risk mitigation and developing a common enterprise architecture to improve understanding of potential areas of risk."

High-Frequency Mapping of the IPv6 Internet Using Yarrp
"Both the number of hosts using Internet Protocol version 6 (IPv6), and the volume of IPv6 traffic, has increased exponentially since 2012. With this adoption, the IPv6 routed infrastructure becomes an increasingly important component of global critical infrastructure and network policy. Unfortunately, the tools and techniques used to perform active network topology discovery were designed for Internet Protocol version 4 (IPv4), leading to a potentially opaque view of the IPv6 Internet. In this thesis, we extend nascent work on stateless high-speed IPv4 active topology probing to develop a new IPv6 traceroute method 'Yelling At Random Routers Progressively version 6' (Yarrp6). Yarrp6 randomly permutes the set of IPv6 targets and hop counts to distribute load, thereby helping to avoid IPv6 response rate limiting. Further, we encode state in the IPv6 payload to permit Yarrp6 to both match responses with probes and use different probe transport protocols. Via active experimentation on the public IPv6 Internet, we compare the results obtained from Yarrp6 against the current state-of-the-art IPv6 topology mapping tool. We show that Yarrp6 can discover topology at more than an order of magnitude faster than previously possible. Finally, we conduct a study of the effect of transport layer protocol on forward Internet Protocol (IP) path inference to determine what protocol is best used for active IPv6 topology discovery."

Detecting Target Data in Network Traffic
From the thesis abstract: "Data exfiltration over a network poses a threat to confidential information. Due to the possibility of malicious insiders, this threat is especially difficult to mitigate. Our goal is to contribute to the development of a method to detect exfiltration of m any targeted files without incurring the full cost of reassembling flows. One strategy for accomplishing this would be to implement an approximate matching scheme that attempts to determine whether a file is being transmitted over the network by analyzing the quantity of payload data that matches fragments of the targeted file. Our work establishes the basic feasibility of such an approach by matching Transmission Control Protocol (TCP) payloads of traffic containing exfiltrated data against a database of MD5 [message-digest algorithm] hashes, each representing a fragment of our target data. We tested against a database of 415 million fragment hashes, where the length of the fragments was chosen to be smaller than the payload size expected for most common Maximum Transmission Units (MTUs), and we simulated exfiltration by sending a sample of our targeted data across the network along with other non-target files representing 'noise.' We demonstrate that under these conditions, we are able to detect the targeted content with a recall of 98.3% and precision of 99.1%."

Multipath Transport for Virtual Private Networks
"Virtual Private Networks (VPNs) are designed to use the Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) to establish secure communication tunnels over public Internet. Multipath TCP (MPTCP) extends TCP to allow data to be delivered over multiple network paths simultaneously. This thesis first builds a testbed and investigates the potential of using MPTCP tunnels to increase the goodput of VPN communications and support seamless mobility. Based on the empirical results and an analysis of the MPTCP design in Linux kernels, we further introduce a full-multipath kernel, implementing a basic Multipath UDP (MPUDP) protocol into an existing Linux MPTCP kernel. We demonstrate the MPUDP protocol provides performance improvements over single path UDP tunnels and in some cases MPTCP tunnels. The MPUDP kernel should be further developed to include more efficient scheduling algorithms and path managers to allow better performance and mobility benefits seen with MPTCP."
