DisViz: Visualizing real-world distributed system logs with space time diagrams
… debugging and learning tool for distributed systems that communicate by message passing. Understanding and debugging distributed systems can be challenging and slow to iterate on, so there is a need for tools that can speed up the time it takes to diagnose the root cause of a bug. There …

Towards trustworthy foundations for operating system Forensics
System logging is an essential component of building and maintaining secure systems. Unfortunately, attackers regularly engage in anti-forensic activities after a break-in, covering their tracks from system logs in order to frustrate the efforts of investigators. In response to this threat, a …

Troubleshooting interactive complexity bugs
… the term to describe the interacting tendency of systems with large number of components. He argued that, in systems with large number of components, multiple failures often interact in some unexpected way, leading to catastrophic failures in systems such as planes or nuclear power plants. He also …

Analysis of Gemini interconnect recovery mechanisms: methods and observations
… extreme-scale high-performance computing (HPC) systems, specifically petaflop-level supercomputers, aimed at solving complex science, engineering, and business problems that require high bandwidth, enhanced networking, and high compute capabilities. The resilience of the network is critical for …

Fault injections on mission-critical computer systems
… of fault injections on mission-critical computer systems with the goal of (1) understanding the impact of faults, errors and failures, and (2) evaluating fault-tolerance and resilience of the targeted systems in the presence of failures. Our first fault injection campaign studies the effects of …

Student use of networked computer workstations: a microeconomic view
… was involved in the initial development of the system. The investigation is founded on three theoretical research areas: the working methods and findings of previous authors are examined by literature review; microeconomic theory is deployed by explaining the operation of relevant models and …

Statistical Learning for Sequential Unstructured Data
… such as texts, human behavior status, and system logs, often presented in a sequential format with inherent dependencies. Probabilistic model are commonly used to capture these dependencies in the data generation process through latent parameters and can naturally extend into hierarchical …

Understanding and mitigating privacy risk in machine learning systems
… a rapid development in machine learning systems and a widespread increase of machine learning applications. However, with the widespread adoption of machine learning, privacy issues have emerged. This thesis studies the privacy risk in modern machine learning systems in two ways. First, …

Log-Driven Robust Anomaly Detection and Root Cause Localisation for Distributed Computing Systems
… services produce large volumes of operational logs that record what components did at the moment events occurred. These records are central during incident response, yet they are difficult to use at scale. Message wording changes across releases, timestamps are not always comparable across …

Distributed AI-defense for Cyber Threats on Edge Computing Systems
… issue, edge-level threat and attack detection systems require specialized solutions that leverage the local computing power of edge systems, take advantage of the close proximity to edge devices (e.g IoT devices and mobile devices), and make use of advanced infrastructure-level aggregation …
