Security failures in web applications persist despite widespread adoption of secure frameworks and best practices. Many of these failures are not caused by isolated implementation bugs, but instead emerge from system-level design decisions, implicit trust assumptions, and misaligned abstractions.
This project investigates security failures in web applications as system-level failure modes, focusing on how architectural design choices, trust boundaries, and abstractions lead to authentication, input-handling, and access-control vulnerabilities under adversarial conditions.
Modern web applications are complex systems composed of interacting components, frameworks, and layers of abstraction. While individual components may appear secure in isolation, their composition often introduces subtle security failures that are difficult to detect through conventional testing or best-practice compliance.
By analysing security failures through a systems lens, this project aims to identify recurring failure patterns and root causes that explain why secure design intentions frequently fail in practice.
- How do architectural design choices influence security failure modes in web applications?
- Which security failures arise from implicit assumptions and abstraction boundaries rather than explicit bugs?
- Why do certain classes of security failures persist across different system architectures?
- How do adversaries exploit system-level inconsistencies and trust boundaries?
The project adopts a system-level experimental approach:
- Define a clear threat model and trust assumptions
- Construct a baseline web application architecture
- Implement architectural variants with identical functionality
- Introduce controlled adversarial interactions
- Analyse observed failures using a failure-mode taxonomy
Rather than cataloguing vulnerabilities, failures are analysed based on their underlying causes and architectural context.

- A taxonomy of system-level security failure modes in web applications
- Empirical observations linking architectural decisions to failure patterns
- Insights into why common security failures evade detection

This project is under active development. Initial focus is on research framing, system design, and experimental structure prior to implementation.
