Title: Innovations by Yu Fu in Cybersecurity

Introduction

Yu Fu is an accomplished inventor based in Campbell, CA (US), known for his significant contributions to the field of cybersecurity. With a total of 7 patents, he has developed innovative solutions aimed at enhancing the detection and prevention of malicious network activities.

Latest Patents

One of Yu Fu's latest patents is titled "Adversarial training for malicious protocol data unit detection with field value perturbations." This invention involves a modular adversarial training data generator that creates adversarial training data for machine learning models. The goal is to detect malicious protocol data units (PDUs) by simulating high-volume cyberattacks through perturbations that can bypass detection systems. For Hypertext Transfer Protocol (HTTP) PDUs, the generator rearranges, replaces, and grid searches values of HTTP header fields to produce this adversarial training data. It also biases the grid search based on metrics that quantify the impact of value replacements on the malicious verdicts generated by machine learning models trained on this data.

Another notable patent is "Inline detection of encrypted malicious network sessions." This invention features an inline malicious traffic detector that captures handshake messages within a session secured by a security protocol. The detector includes a classifier that assesses the session and determines whether it is malicious or benign. The classifier is trained on labeled sessions using custom features derived from handshake messages. If the session is identified as malicious, the inline malicious traffic detector takes action to block it.
