내부자 위협 (Insider threat)
Definition
Harm from insiders (malicious or careless); a hijacked account also behaves like one.
For executives (CEO·CISO)
Focusing on external defense, orgs overlook insiders who hold the most access — and a hijacked account ultimately behaves like a normal insider. Commonly missed: beyond least privilege and behavior monitoring, enforce immediate access revocation on departure/role-change (offboarding) — a frequent failure point.
