A leak is the unintended release of a substance, such as a gas, liquid, or other material, from a container, pipe, or other enclosed structure. In a broader sense, it can also refer to the unauthorized disclosure of sensitive or confidential information. The term is derived from the verb "to leak," which means to escape or flow out through a hole or crack. In Hebrew, "leak" can be translated as דליפה (dilifa). In other languages, it is known as fuga in Spanish, fuite in French, and Leck in German. Leaks can occur in various contexts, including industrial settings, plumbing systems, and digital data storage. In industrial and plumbing contexts, leaks can lead to significant losses, environmental damage, and safety hazards. In the realm of information security, leaks can compromise sensitive data, leading to legal, financial, and reputational consequences. Effective leak detection and prevention measures are crucial in mitigating these risks.
