Timeliness, Relevancy, Accuracy

Timeliness (Recent or current data)

Intelligence sources must be up to date. Threats diminish, change, and evolve. Adversary groups adopt different tactics. You must assess whether an intelligence source can research and disseminate updates in a timely manner.

Relevancy (Does it pertain to your objective)

Intelligence sources must match their use case. Example: a threat intelligence source that focuses on Windows security is of limited use if your systems are primarily cloud applications accessed via Chrome OS workstations.

Accuracy (Is the intelligence correct?)

Intelligence sources must produce effective results. Accuracy can also refer to whether the intelligence is of a general or specific nature.
