Improving Cybersecurity Posture with an AI Security Assistant
summary
An AI security assistant that automates mapping of CVE-style vulnerability descriptions to MITRE ATT&CK’s 14 tactics and 600+ techniques, enriching each finding with related threat groups, mitigations and detection notes. Core stack: sentence-transformers for semantic embeddings, vectors stored as Parquet/ChromaDB and indexed with FAISS, LangChain for orchestration and RAG, and OpenAI embeddings for Q&A. Deployed inside an EU Cyber4D CRRT toolbox, supports chat and voice, and demonstrably returns relevant ATT&CK mappings to help prioritize and mitigate risks.
