About this interactive
The attack surface is every way in, and the lesson splits those ways into four. Physical means the attacker reaches the equipment: plugging into a port, dropping a rigged USB stick, carrying removable media in. Digital means reaching in over a connection without being present: an open wireless network, a scanned-open port, malware or a booby-trapped file. Social engineering means working through a person: a phishing email, a pretext phone call, a message that impersonates a coworker — the target is the human, not the machine. Third party means coming in through an outside entity the organization trusts: a partner connection, a managed provider, a tampered supplier update. Ask what the attacker actually used — a wire, a connection, a person, or the trust of another organization — and the category follows.
