Latest Patents

One of Zhixing Xu's latest patents is titled "Analyzing privilege escalation risks using a multi-layer reasoning framework." This patent describes techniques for analyzing privilege escalation risks within the accounts, roles, and policies that comprise an organization's cloud provider environment. Privilege escalation refers to scenarios where a principal, such as a person or application, gains access to resources or actions that exceed the intended level for that principal. The patent emphasizes the importance of identifying misconfigurations of policies and permissions attached to identities within an organization's environment. A multi-layer reasoning framework is utilized to build an ontology model of an organization's identities and their relationships, enabling the identification of specific privilege escalation risks.

Another notable patent by Xu is "Specification language for generating graph reachability-based analyses for cloud-based system resources." This patent outlines a domain-specific language and framework for implementing analyses of security, operational, or functional properties involving computing resources. The specification language allows users to define the semantics of cross-resource relations in a human-readable format. This flexibility enables users to modify existing analyses or create new ones, enhancing the overall security and functionality of cloud-based systems.
