China's policy towards US adversaries
… why does China diplomatically support adversaries of the US such as Iran, Sudan, Libya, and Syria? This thesis shows that soft balancing against the US in concert with Russia best explains China's foreign policy towards these states. Economic interest and a number of other alternative …

Robust Computer Vision beyond Lₚ Adversaries
Deep learning computer vision systems, integral to technologies such as self-driving cars, facial recognition, and content moderation, require robustness against diverse perturbations to ensure reliability and safety. Examples of such perturbations include variations in lighting conditions, …

Revealing Molecular Adversaries of Human Health Using Advanced Imaging Technology
Single particle electron microscopy (EM) allows us to examine the molecular world and gain insights into protein structures implicated in human disease. Visualizing the 3D architecture of the macromolecules can inform drug design and preventative care. While X-ray crystallography and NMR are able …

Coevolving Cybersecurity Adversaries for Industrial Control Systems in Failure-Prone Environments
As industrial control systems become universally integrated with software and connected to the internet, they have become targets for cyberattacks and sabotage. Detecting cyberattacks on these networks is difficult because existing datasets on attacks is minimal and the bulk of intrusion detection …

Protecting anonymity in the presence of autonomous system and internet exchange level adversaries
… system (AS) and Internet exchange (IX) level adversaries on Tor, currently the most widely deployed and used anonymity overlay network. Of particular interest is the possibility of a single AS or IX point observing both the path from the client to the entry node and the path from the exit node …

Quantifying Trust and Reputation for Defense against Adversaries in Multi-Channel Dynamic Spectrum Access Networks
… attack strategies are more effective from the adversaries* perspective. Through extensive simulation experiments we show that the trust models are effective in identifying malicious nodes with a high degree of certainty under variety of network and radio conditions. We show high true negative …

A model for real-time data reputation via cyber telemetry
… (HVA) as defined by information sets that our adversaries most typically target. The Continuous Diagnostic and Mitigation (CDM) initiative aims to establish a unified security posture across the federal space with a specific focus on HVAs. This work examines federal cybersecurity initiatives …

Investigating Security Threats of Resource Mismanagement in Networked Systems
… systems have been exploited or compromised by adversaries, due to misconfiguration and mismanagement of human errors. In this dissertation, we explore different network systems to identify security vulnerabilities that adversaries could exploit for malicious purposes. First, we investigate the …

Building practical systems that compute on encrypted data
… Thus, existing systems naturally try to prevent adversaries from compromising these servers. However, experience has shown that adversaries still find a way to break in and steal the data. This dissertation shows how to protect data confidentiality even when attackers get access to all the data …

Game-Theoretic Learning and Control for Resilience of Complex Adaptive Systems
… rendering them vulnerable to malicious adversaries who seek to create damage. It also leads to a lot of uncertainty, which traditional model-based control methods are unable to handle effectively. Drawing motivation from this reality of things, in this dissertation, we focus on two …

Nuclear bargaining : using carrots and sticks in nuclear counter-proliferation
… the two is more pronounced when dealing with adversaries than it is with allies. With allies, both sanctions and inducements can be effective, but inducements are more likely to secure long-term cooperation. With adversaries, negative sanctions are not only much less effective than …

What causes credibility? : reputation, power, and assessments of credibility during crises
… Is the reputation hypothesis true? Will our adversaries predict our future actions by looking at today's decisions? More generally, do decision makers predict their adversaries' actions in a crisis by looking at the adversaries' previous actions? I test the reputation hypothesis against a …

The PCF and the question of intellectual workers : the crisis of social ideology
… proper distinctions between potential allies and adversaries. The thesis posits the view that the PCF has failed to make correct distinctions between its potential allies and adversaries and has thus pursued unsuccessful alliance strategies. The thesis contributes towards a scientifically-based …

Protecting critical infrastructure systems using cyber, physical, and socio-technical models
… countermeasures can mitigate attacks by outsider adversaries, attacks by insider adversaries would still succeed. Reapplication of our security analysis with the addition of the cyber-attack vectors that we discovered shows that adversaries prefer to use physical and social means to gain access to …

Mind the Gap: The Failure of the Central Intelligence Agency to Support U.S. National Interests
… covert action and accurate assessments of its adversaries have proved problematic. This has manifested itself in areas such as the soviet threat during the Cold War and towards the rogue nation of Iraq. Covert activities tended to supplant U.S. policy, and often failed to advance U.S. interests …
