Introduction

Zhiyun Qian is a notable inventor based in Franklin Park, NJ (US), recognized for his contributions to cybersecurity technologies. He holds a total of 3 patents, showcasing his innovative approach to addressing complex challenges in the field.

Latest Patents

Zhiyun Qian's latest patents include "Differential dependency tracking for attack forensics" and "Discovering and constraining idle processes." The first patent focuses on methods and systems for intrusion attack recovery, which involve monitoring multiple hosts in a network to generate audit logs of system events. This process generates dependency graphs (DGraphs) based on the audit logs, allowing for the determination of a relevancy score for each edge of the DGraphs. Irrelevant events are pruned to create a condensed backtracking graph, which helps locate the origin of an attack by backtracking from an attack detection point. The second patent addresses process constraints by collecting system call information for a process. It detects whether the process is idle and uses autocorrelation to determine if the process issues system calls periodically. If the process is found to be idle or repeating, it is constrained to limit the attack surface.
