In the context of abuse case scenarios, the 'Threatens Relationship' is used to describe the interaction between an abuse case and the use case it threatens. This relationship helps to identify potential security threats and the ways in which they can exploit the functionalities of a system. By mapping out these relationships, developers and security engineers can better understand the attack vectors and design appropriate security measures to mitigate them.
