A security champion is a developer with a vested interest in security who helps to amplify the security message at the team level. Security champions don't need to be security experts; they just need to act as the security heartbeat of the team, keeping their eyes and ears open for potential problems. In turn, once the team is aware of these issues, it can then either fix the issues in development or call in your organization's security experts to provide guidance.
