Why is relying solely on 'security by being open' not always effective?

Understand the Problem

The question asks why relying solely on the principle of "security by being open" (i.e., open-source security) isn't always effective. It implies that while open source can contribute to security, it's not a foolproof or complete solution. We need to identify the reason from the provided options.

Answer

It creates a false sense of security and becomes vulnerable once the obscurity is breached.

Relying solely on 'security by being open' is not always effective because it can lead to a false sense of security, neglecting other essential security measures. Once the obscurity is breached, the system becomes vulnerable since its protection was based on secrecy rather than robust security practices.

More Information

Security by being open, also known as security through obscurity, is the practice of relying on the secrecy of design or implementation to provide security. It assumes that if attackers don't know how a system works, they can't exploit it.

Tips

A common mistake is assuming that obscurity alone is sufficient for security. Always implement security in layers.
