Security Profiles
A Knowledge Extraction Framework on Cyber Threat Reports with Enhanced Security Profiles
Yongxin Cai · Jing Qiu · Fan Zhang · Qiang Li · Lei Chen
This work presents a unified framework for extracting structured threat knowledge from unstructured cyber threat reports and constructing enhanced security profiles to support downstream analysis, correlation, and automated defense.
- Fine-grained entity and relation extraction from CTI narratives
- Security-profile construction across multiple threat dimensions
- Knowledge reuse for detection and defense automation

Sigma Rule Generation
From Texts to Rules: Generating Sigma Rules with Large Language Models from Cyber Threat Reports
Yongxin Cai · Jing Qiu · Qingming Li · Du Cheng · Lei Chen
An end-to-end framework that converts cyber threat reports into executable Sigma detection rules by bridging semantic gaps across extraction, attack description generation, and rule synthesis.
- Multi-stage semantic descent from CTI to Sigma
- Parameter-cached RAG for robust rule generation
- Executable command–rule alignment
