To prioritize security, quality development practices, and robust governance controls is crucial for software engineering leaders given the increasing number of data beaches. The authentication system is a critical area that requires careful attention to ensure customer trust and minimize risks. Building an authentication system from scratch can introduce errors, while using third-party services can reduce risk and speed up development. It's essential to bake security controls into the software development process through automated code linting, static code analysis, periodic penetration testing, code review, coding standards, security training, senior developer coaching, and pair programming. Implementing these measures can significantly impact the overall security of the system.
