You have a video of suspect entering your office the day your data has being stolen?

Direct evidence proves a fact without requiring any inference, such as a witness directly observing the suspect exfiltrating files; a hallway entry video alone does not meet this standard.

Indirect evidence does not directly prove a conclusion but requires an inference to link it to the crime in question. The video places the suspect at the scene but does not directly show them stealing data, making the connection inferential rather than self-proving. In digital forensics, indirect evidence - also called circumstantial evidence - is contrasted with direct evidence that proves a fact entirely on its own.

Circumstantial evidence is functionally synonymous with indirect evidence and describes the same inferential type of proof, but it is not the labeled correct answer in this question's context.
