If an e-commerce site was put into a live environment and the programmers failed to remove the secret entry point that was used during the application development, what is this secret entry point know

SDLC (Software Development Life Cycle) is the overall process for planning, developing, testing, and deploying software, not a specific hidden entry point.

A honeypot is a deliberately exposed decoy system or resource designed to attract and monitor attackers, not a developer-created secret entry point.

SQL injection is an attack technique that exploits unvalidated input to manipulate database queries, not a hidden entry point left by a programmer.

A trap door (also called a backdoor) is a secret mechanism embedded in an application by programmers to bypass normal authentication or access controls during development. If left in a live environment, it provides an unauthorized pathway that attackers can discover and exploit to gain privileged access. This is a recognized secure SDLC risk and is distinct from externally introduced vulnerabilities.
