Systems and methods for securing a keyed fiber optic network assembly are provided. A typical network system includes an assembly having a security feature and adapted to facilitate fiber optic communication between two mating fiber optic connectors. The security feature is uniquely keyed to disengaged when mated with a corresponding uniquely keyed connector. The security feature includes at least an inner door and a spring and is adapted to prevent optical communication and mating with a receiving connector during illegitimate connector insertion. A typical network includes a plurality of assemblies each having a uniquely keyed security feature. Each of the plurality of assemblies is color coded to match with a legitimate color coded connector to provide guidance to a network user. The connector and the security feature are uniquely keyed through unique positioning of protruding bosses.
