일반적인 결과

범위	영향	가능성
Authentication	Gain Privileges or Assume Identity 참고: If an authentication artifact is used across multiple applications or services, it allows an adversary who is able to compromise the authentication artifact to gain access to all applications or services that use that artifact.
Availability	Other 참고: In order to revoke access to an adversary who has compromised a shared authentication artifact, that artifact must be invalidated which would affect the availability of any user who has legitimately obtained the artifact to authenticate.

잠재적 완화 방법

Phases : Implementation
Enforce re-authentication per user device. This prevents another user from obtaining the singular authentication artifact and making authenticated requests without authenticating.
Phases : Implementation
Use unique authentication artifacts per user device that will only be accepted if used on that device.
Phases : Implementation
Ensure that unique authentication artifacts are used for each application or service within an organization to prevent potential reuse across applications.
