Can you share one example of how you implemented security measures in a backend application? What aspect of security do you focus on most?

In one of our projects at Software House, we implemented OAuth 2.0 for secure authorization in a backend application. By using OAuth 2.0, we allowed users to authenticate with trusted third-party services like Google or Facebook, ensuring we never stored sensitive password data directly. The aspect of security I focus on most is data protection, especially safeguarding user information during transit. We use SSL/TLS encryption and token-based authentication to ensure that data is always encrypted and that only authorized users can access specific resources, minimizing the risk of data breaches.
