Context of use is the specific situation in which a response, rule, or instruction is meant to be interpreted and applied. In cyber security, the same statement can be safe in one environment and dangerous in another. A password-reset step, access-control rule, or incident-response procedure may be correct only for a certain team, system, time period, or approval level.
This matters because attackers and weak workflows both exploit context loss. A phishing email may quote a real policy fragment to sound legitimate, while an internal AI assistant may return a stale procedure that no longer matches current controls. Defenders reduce this risk by tagging knowledge with version, owner, scope, and approval status, then checking that any retrieved answer matches the user’s role and situation before it is used. Context of use turns information into actionable guidance only when its limits are known.
