Strengthening Machine Learning-based Intrusion Detection Systems in Adversarial Environments

Machine learning has seen significant advancements in recent years and has proven to be highly effective in a wide array of applications, including intrusion detection systems (IDS). However, while working in adversarial environments, machine learning-based systems are known to be vulnerable to a range of attacks. In this talk, we will discuss techniques aimed at strengthening machine learning-based IDS. On the one hand, we explore techniques for enhancing the performance and robustness of IDS in adversarial environments, where we propose a contrastive learning-based approach that builds highly differentiating IDS. On the other hand, we develop efficient security mechanisms to thwart common attacks, including an adversarial example (AE) detector that filters out suspicious inputs at the model testing time, and a robust model evaluation method that leverages latent space representations to build resiliency in model aggregation against model poisoning attacks in federated learning. This talk will report our research results along this line of research.

Enhancing Security in Software and AI

Cybersecurity has emerged as one of the foremost priorities on the global research and development agenda today. The urgent need for new and innovative cybersecurity technologies capable of effectively addressing this pressing danger cannot be overstated. Software security is paramount to maintaining the integrity of modern software applications. Given the broad spectrum of real-world applications, different security challenges are evaluated based on the specific use case. In this presentation, we will dissect a variety of security issues that have arisen in diverse applications, examining both the associated challenges and effective strategies in software security. We will delve into the technique of fuzzing, an efficient and effective automated process vital for software testing. Additionally, we will explore strategies for detecting security vulnerabilities in software. We will also scrutinize security considerations in binary code applications, including those in IoT devices and Windows low-level components. By viewing AI models as software, we will further address the significant security problems present within deep learning models.
