During December 2024, Kor Zijl enhanced the microsoft/ARI repository by implementing certificate-based authentication for Azure Resource Inventory, focusing on secure automation for service principals. Leveraging PowerShell scripting and Azure CLI, Kor introduced a certificate path parameter and updated the login flow, accompanied by revised documentation to align with best practices in authentication and security. Additionally, Kor addressed a credential leakage issue by modifying Connect-AzAccount output handling, ensuring sensitive information is no longer exposed in the console. The work demonstrated a strong understanding of authentication mechanisms and security posture, delivering both functional improvements and risk mitigation within a short development period.
