PROFILE
Yacin Nadji
Over a two-month period, contributed two features to the zeek/zeek repository, focusing on network programming and protocol analysis using C++ and Zeek scripting. Developed a built-in function for validating IPv4 and IPv6 subnets in CIDR notation, mirroring existing IP validation logic and ensuring comprehensive unit test coverage. Later, implemented a new event to report RFB authentication outcomes with correct true/false semantics, deprecating the previous event to improve reliability for downstream analytics and alerting. Demonstrated careful deprecation management, event-driven design, and attention to backward compatibility, with all changes documented, reviewed, and aligned to enhance the project’s consistency and maintainability.

Oct 1, 2025October 2025: Implemented a correctness-focused update to RFB authentication reporting in zeek/zeek. Delivered a new event rfb_authentication_result to correctly report authentication outcomes, deprecating the inverted-logic rfb_auth_result. True now signifies success and false signifies failure, aligning with standard semantics. This change improves downstream security analytics, dashboards, and alerting reliability by providing consistent semantics across the authentication pipeline. The work is captured in commit 68be290d36b49e608da5471c744cd7b2d48c89f6. Skills demonstrated include Zeek scripting, event-driven design, deprecation strategy and backward compatibility, code review discipline, and cross-team communication.
