What is meant by "security by obscurity"?

The correct answer defines "security by obscurity" as a concept that relies on keeping information secret to protect it. This approach suggests that if the details of a system or its security measures are hidden, the system will be protected from attackers. However, this strategy is generally viewed as insufficient when used alone because it does not address the underlying vulnerabilities of the system.

Effective security involves multiple layers of protection, which include robust security practices and technologies. Relying solely on secrecy can give a false sense of security, as determined attackers may still discover the hidden information or vulnerabilities through various means, such as reverse engineering or social engineering. Thus, security by obscurity should be considered a minor aspect of a comprehensive security framework, rather than a standalone solution.

In contrast, a reliable security strategy suitable for all organizations, emphasizing transparency in security practices, and using encryption to hide access, represent approaches that complement rather than rely solely on obscurity. These methods focus on proactive measures and resilience against attacks, rather than simply hoping that certain details remain hidden.
