Worked on enhancing network security by expanding the IP blocklist in the ZCSOC/az_zal_blocklist repository, focusing on threat prevention and reducing exposure to unauthorized access. Delivered a feature that updated the ip_list through eight targeted commits, ensuring a scalable and auditable approach to managing unwanted traffic. Emphasized data-driven security controls and maintained a clear, consistent commit history for traceability. Utilized system administration skills and plaintext configuration to implement these changes, enabling rapid iteration on defensive measures. No major bugs were reported during this period, reflecting a stable deployment and careful attention to detail in the ongoing maintenance of security infrastructure.
