penetratable

Penetratable is an adjective used to describe something that can be passed through or pierced. It implies a lack of resistance to entry or penetration. The term is often used in contexts where the ease or difficulty of passing through a material or object is relevant.

For example, a soft material like fabric is penetratable by a needle, while a hard material like steel is not easily penetratable. In cybersecurity, a system's penetratability refers to how easily it can be breached by unauthorized access. The concept also applies to physical barriers, where a penetratable wall might be easily broken down. The degree of penetratability can vary greatly depending on the nature of the object and the force or agent attempting to penetrate it. Understanding penetratability is important in fields ranging from materials science and engineering to security and military strategy.
