Alan Hernández enhanced network security in the Blu-Teams/Bloqueos repository by implementing an IP whitelist update, allowing two additional trusted IP addresses to access the system. Focusing on precise access control, Alan configured the network policy to reduce the attack surface and restrict entry to authorized networks only. The work was fully documented and traceable through version control, demonstrating disciplined repository management. Leveraging skills in network security and configuration management, Alan delivered a targeted feature that strengthened the security posture without introducing operational complexity. The update was implemented in plain text, reflecting a focused, single-feature contribution with clear, reviewable ownership.
