Hi, I'm Ronan!
Cybersecurity Professional,
MS Student @ Northeastern
-
Access-Governed RAG Console (LLM Access Control + Entra ID SSO)
- Built a RAG assistant that enforces role-based access control at the retrieval layer, so restricted documents are excluded from a non-authorized user's candidate set before the model ever sees them
- Integrated real Microsoft Entra ID (OAuth2) sign-in with app-role claims mapped to backend RBAC, plus a demo-login fallback so the repo runs with zero external setup
- Added a prompt-injection scanner (validated by a 10-case attack battery, 10/10 resisted) and full audit logging of every access decision; deployed to Azure App Service

-
NIST 800-171 / CMMC Compliance Baseline Lab
- Configured Active Directory, Group Policy, Microsoft Intune device compliance, and Entra ID Conditional Access requiring device compliance for cloud app access
- Hardened Windows Defender Firewall rules and authored a System Security Plan mapping every control to its NIST 800-171 requirement
- Built a CMMC Level 2 self-assessment scorecard scoring 12 of 15 practices met, with remaining gaps documented as next steps
