Security by Obscurity
When building an application, if the security you have is based on the fact that people will not figure it out, what you see in this picture is exactly your reality. It is called security by obscurity and it is NO security. In no time, someone will soon stumble on it and exploit it.
Whenever you think about security, you need to think of critical ways to implement it. No application is bug proof but don’t make it too cheap to detect.
It is better to be over prepared than to underestimate a threat.
