PROFILE
Kathir2434
Kathir Krishnan worked on the ZCSOC/az_zal_blocklist repository, delivering a series of configuration-driven updates to refine network access control and strengthen security posture. Over six months, Kathir managed IP allowlist and blocklist entries through precise, auditable changes, focusing on data management and system administration without altering application logic. Using Git for version control and leveraging skills in configuration management and network security, Kathir maintained operational stability while reducing exposure to unauthorized traffic. The work emphasized small, well-documented commits, enabling clear traceability and efficient policy enforcement, and demonstrated a disciplined approach to repository governance and security-focused configuration updates.
